Other Big Game / The Effects of Hog Hunting on Wild Pig Behavior
« on: April 13, 2018, 07:12:02 AM »
The following is the latest information from the Texas A&M Newsletter Spring 2018 feral hog studies.
Unfortunately I was unable to transfer it as a link of any kind, and had to copy it best I could.
For anyone who hunts hogs, its well worth the read.

Hunting Can Accelerate Wild Pig Birth Rates
It is generally accepted that sport hunting wild pigs will
not significantly reduce populations. Perhaps less
apparent is that human activities such as hunting can
induce evolutionary ramifications at both the population
and species level (Darimont et al. 2009). A good
example of this has been observed in deer species
(Odocoileus sp.); whereas high rates of trophy harvest
were shown to lead to smaller overall horn size and body
mass over time (Coltman et al. 2003). In wild pig
populations, though, high hunting pressure doesn’t
necessarily lead to reduced body sizes or smaller tusks.
Extensive monitoring of wild pig populations over 22
years found that high hunting pressure can actually cause
wild pigs to advance offspring birth rates by as much as
12 days per gestation cycle (Gamelon et al. 2011). This
acceleration in birth rate is further compounded by
increased conception rates of sows within their first year
of life when populations experience increased adult
mortality from hunting or other abatement efforts
(Gamelon et al. 2011). Essentially, wild pigs may breed
earlier and produce offspring more quickly when
subjected to hunting pressure. Given this novel survival
strategy, it becomes more understandable why a state like
Missouri banned completely the sport hunting of wild
pigs on conservation lands.
Instead of flushing, some wild pigs have adapted to evade helicopters
by holding within dense cover.
2
Wild Pig Adaptations to Aerial Gunning
Aerial gunning is an effective population reduction
strategy unless limited by topography or dense canopy
cover (Campbell et al. 2010). However, previous research
has shown that wild pigs can intelligently adapt their
behavior to avoid detection and flushing by helicopters
(Saunders and Bryant 1988). It might be assumed that
these animals would simply disperse from their home
range in response to aerial gunning efforts. In fact,
research indicated the opposite in that core area and home
range sizes did not alter either before or after enacting
aerial control (Campbell et al. 2010). Instead, wild pigs
can adapt to aerial gunning by seeking dense cover and
refusing to flush from it despite concerted efforts by the
pilot and crew.
Research indicated that wild pig sows subjected to high hunting
pressure had higher conception rates in their first year and
produced offspring up to 12 days sooner than normal gestation.
What is significant about this behavior is that until
relatively recently wild pig populations had not
encountered significant predation from above their line of
sight. Despite this, they have quickly adapted to be
capable of intelligently evading a formidable 5000 pound
“aerial predator” that otherwise would seem to have every
advantage. The intelligence and adaptability of wild pigs
are key factors that compound effective control (Sweeney
et al. 2003), and this is again evidenced by their potential
to learn to evade aerial gunning efforts.
Trap Aversion
Research has long documented trapping as an effective
population reduction technique, with 70-80% reductions in
populations having been reported using this technique
alone (Saunders et al. 1990, Vernes et al. 1999). However

wild pigs can adapt to avoid traps altogether for a variety
of reasons. This can occur due to the size and type of
trap used, but also can be attributed to inadvertently
“educating” wild pigs through incomplete captures. With
the exception of solitary adult males (boars), wild pigs
travel in social groups called sounders. When trapping
these animals, it is important to target and remove the
entire sounder in a single trapping effort. This is
generally accomplished through a process of pre-baiting
and conditioning the group over time to routinely enter a
trap large enough to contain the entire sounder. Corral
style traps are often best suited for this, and research
indicated this type of trap to be four times more effective
than conventional box traps (Williams et al. 2010). Box
traps, while valued for their portability, usually
only capture 1-3 animals at a time. No matter what type
of trap is used, incomplete captures can divide sounders
and cause remaining pigs to avoid traps in the future.
Wild pigs will attempt to escape traps if given the opportunity. Ensure
that traps are constructed properly and check traps at first light to
help minimize trap escape attempts. (Image Credit: Andy James)
In order to minimize learned trap aversion due to incomplete
captures, the goal of any trapping effort should be to target and
remove the entire sounder of wild pigs.
Trap Escape
Wild pigs can also adapt to escape traps, and individuals
that learn to do so often exhibit this behavior repeatedly.
Trap escapes can be accomplished through climbing,
rooting, exploiting trap design flaws and even jumping
considerable heights in excess of 4 feet. It is important
to construct and implement sound trap designs, and it is
equally important to check traps as soon as possible
following each trap night. Many experienced trappers
check their traps at first light and bring a firearm in order
to harvest any residual pigs that may be near the trap site
due to incomplete capture or escape. The Texas A&M
Natural Resources Institute recommends that corral traps
be constructed with four to six 16’ cattle panels that have
5’ panel height and 4” mesh in order to minimize trap
escapes. It is generally not necessary to bury or trench
paneling underground, but it is important not to leave any
gaps at ground level or near the head gate. Game cameras
can be integral in monitoring wild pig activity at traps
sites, and can also help to identify any modifications
necessary in order to minimize the potential for trap
escape.
Conclusion
Wild pigs exhibit a variety of behavioral responses to
abatement pressure. Their intelligence and adaptability can
complicate effective control, factors that are only
compounded by their extreme fecundity. It is important to
select appropriate strategies as well as to adapt control
techniques as necessary in order to minimize any potential
issues which can reduce the success of abatement efforts.
This can undoubtedly be easier said than done, as is
evidenced by the numerous and often remarkable ways in
which wild pigs can evade control efforts despite the best
technologies available to man. However, best management
practices including trapping, aerial gunning, strategic
shooting, snaring, and the use of trained dogs remain
proven tools that, when implemented in a combined
approach, can successfully abate the damages associated
with wild pigs.

Rifles / Weatherby Calibers
« on: April 11, 2018, 06:05:30 PM »
Its been approx. 73 years since Roy Weatherby designed the first of his great calibers. It took all of the money he could scrape together, a lot of outside the box thinking, and countless hours were invested to try and prove his theory that velocity conveyed hydrostatic shock. All with the basic tooling of the day. If he had been content to be a rifle maker and never invented these calibers, how long do you suppose before someone else would have developed them? Was his case, bolt, and rifle design radical enough that it would have been 10, 20, or more years (from 1945) before these calibers may have been developed? Just hypothetical. Anyone's thoughts?

Whitetail Deer / Processing your own deer
« on: April 08, 2018, 07:01:11 AM »
I came across a Realtree hunting article that I thought might benefit young hunters, first time hunters, and might even serve as a refresher for the rest of us. Its basically a DIY guide to field dressing, skinning, quartering, and even a few cooking tips. It includes videos which serve as a good visual for first timers. How many of us have taken young kids to the hunting camp for their first time hunting experience? When the processing starts the first thing out of their mouths is "Gross" and some are squeamish. Exposing them through these videos may help lessen the Shock of seeing blood and guts for the first time.  My granddaughter was pretty upset her first time. If you think theres a better way of doing any of these things, you can let the kids know at the time how you do it.

Around the Campfire (General Discussion) / Happy Easter/ Passover
« on: March 30, 2018, 11:58:44 AM »
Happy Easter and Happy Passover to all the Weatherby Nation and their families. Its a good time to reflect on life in general, keeping the Faith and knowing that in Forgiveness there is Hope. Special Prayers and Gratitude to all in the Military and Law Enforcement, past and present, who risk, an put their lives on the line for us everyday. Its also another chance for our kids and grandkids to have a fun time with the Easter Bunny, and maybe learn something too. God is good, all the time. Happy Easter and God Bless everyone.

Democrats have introduced an assault weapons ban again and use the same lame arguments. Florida's Congressman Ted Deutch the Parkland representative also got behind the bill.
Of importance is Florida's 18th congressional district rep, Brian Mast's stand against the weapons ban on MSNBC and his views as a combat veteran and double amputee. Someone who fought for our country. Article below:

 My son-in-law called to tell me about something that happened yesterday. Said his friends wife took their seven year old son hunting and had an accident in the blind. Seems the Mom and boy saw a deer, so they put in their ear plugs while she got ready to load and shoot. She loaded her 270 Remington and pointed the rifle out of the blind. She squeezed the trigger and there was a huge explosion. The stock broke in half and the action got blown out. Turns out she loaded a 308 cartridge into the 270 by mistake. She sustained a few scratches on the face, but her face got completely swollen. Her right hand got badly cut. The little boy wasn't injured at all, but I'll bet he remembers that experience the rest of his life. The lady said she unknowingly took shells from the wrong box(they were new original boxes, but she took ammo from the wrong box)and put the loose shells in her jacket pocket. Pretty much the end of the story.
I told my son-in-law that I didn't think it was possible to load a 308 into a 270 chamber, but he said thats what happened.( Pretty sure the 308 WSM would not have fit and I do know that there are other combinations like shooting 556 ammo in a 223 that might cause bodily injury ) I’m not familiar with all makes and models of 308’s and 270’s, or their chambering, much less chamber dimensions, but at this point, I will assume Murphy’s Law applies. Anyway, after we hung up, I started doing some research. I read many different accounts from other forums about this same kind of thing happening, but only found one printed article from “GUNS MAGAZINE” that actually discussed this type of accident at length. Disclaimer: I don’t know how accurate or factual this article is, and it could use some editing help:

 The following excerpt is from the article and the link is below this excerpt:

”The .270 Win and .308 Win have the same case-head diameter and similar body dimensions. If the shorter .308 cartridge is fired in a .270 chamber it isn’t big enough to seal the chamber, and high pressure (as in, 65,000 psi) will get loose in the action causing the rifle’s destruction.”

Rifles / Barrett Firearms(the 50BMG guys) develop a bolt action
« on: October 25, 2017, 05:04:14 AM »
Read an article in the latest issue of American Hunter on Barrett's latest offering and thought I'd share it, but couldn't find the digital version. Since their not known for bolt actions, I wonder which markets they will try to infiltrate to get recognition. I felt the rifle had a few features that were suspect, not bad just suspect, its offered in std. calibers and comes in at 5 lbs. total weight.(real ultra light weight) The link is pretty thorough:

The Glock 46 is essentially a Gen 19 with ergonomic changes and a new twist for Glock. They have gone to a cam-actuated rotating barrel action for the German pistol only, instead of the tilting barrel locking system which is currently used by most mfg’s. Its not a new concept, but it is a prototype for Glock. This pistol is not going to be available to the American market, at least not for now. Currently several mfg’s offer pistols that use a rotating barrel action, and claim that it reduces barrel flip and perceived recoil. If anyone in the Nation has a pistol with the rotating barrel action, I’d like to hear their opinion on it verses the tilting barrel action. Glock also has a patent pending on their new rotating barrel system. I’ve added a link with details on the Glock 46, and also added a video I found on youtube on the Beretta PX 4 rotating barrel system and how it works.

Whitetail Deer / Scoring Whitetails
« on: July 07, 2017, 12:30:55 PM »
Found a link where you can challenge your skills at scoring whitetails. There are a couple of hundred  photos to look at, in which you try to determine the score of the deer in the photo within 45 seconds. It even has a "How To Field Score" as a quick refresher course. Click on the "How to Play", its real easy and fun ;) Some of the photos are tricky, and you won't agree with all of them. I know I didn't.  As long as you don't close the page out, you can keep coming back to it as often as you have time. Its self explanatory, easy, and logging in doesn't commit you to anything. Have fun on sleepless nights. ;D
