 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

The squabble to ditch the 5.56mm has gone on for decades and it seems that changes may come to pass in the near future. While the 5.56mm gave more fire power and less weight for the solider to carry during combat, I never felt that is was an effective alternative to the 30 cal. It didn't help that all the bugs had not been worked out when the 5.56 was first issued, and to date, some problems are still experienced within the platform. This "Army Times" publication gives some details. Do you think its time for a change?

Handguns / Hollywood's Movie Star/The 45 Colt 1911 an impostor?
« on: June 05, 2017, 09:25:18 AM »
Found a bit of Hollywood history on the use of the 1911 Colt 45 that may only be interesting to handgun movie buffs and Colt 45 aficionados, but thought I'd post it just the same.(It's a bit winded)

A day of remembrance and to give thanks to all the Veterans who have died while serving in the country's armed forces, and also to those who bravely serve now or have served with honor to protect our country. John 15:13 No one has greater love than this, to lay down one's life for one's friends. The Greatest Generation chose to serve knowing the consequences, so that unknown generations might continue to be blessed with the the Rights and Freedoms given to us by our Lord. Lest we forget those who have made the ultimate sacrifice, those who have served and those who currently serve and carry the torch of freedom in their hearts. God bless each and every one. A special acknowledgement.

Wondering if any of you handloaders have ever used the Birchwood Casey "Brass Cartridge Case Cleaner"? Down side comments or positive feedback welcome. Are liquid cleaners in general not considered to be in the the same class as the long accepted tumbler style Cleaners? Heres the Birchwood Casey link:

Reputable mfg's blemished bullets, and overruns, not damaged or that have been withdrawn from current production, (possibly and old style) is there a reason or should hand loaders not trust them to use for their hunting use. Should they only be used to work up loads, and for practice, or are they completely reliable and safe?

Ammo / Improve your ammo with great bullets!
« on: April 17, 2017, 02:32:24 PM »
The bullets listed in this link aren't the only great bullets around, but they are impressive for their intended use. I haven't used any of them in loaded ammo or re-loading yet, but I'm planning on it. If you've hunted with any of these bullets, how did they perform, and if you've hand-loaded any of them, were any quirkier then others? Enjoy

Reloading / Reloading Basics?
« on: April 17, 2017, 08:29:14 AM »
I found this article over the weekend and thought it would be interesting to get other hand loaders opinions on primer applications across the board. John Barsness wrote it about 12 years ago.

Primers and Pressures by John Barsness
Many handloaders think a
primer is a primer, or differentiate
only between
�standard� and �magnum� primers.
But primer choice can make a big
difference in load performance�
and a REALLY big difference in
safety.
This has been known among
shotgun handloaders for years, but
too many rifle handloaders rarely
consider the side-effects of
primers. Various experiments (including
some I�ve performed myself
) have shown that the choice of
rifle primer can change the pressure
of the same load over 12,000
pounds per square inch (psi). This
means a load that produces a very
safe 58,000 psi with one primer
can produce an unsafe 70,000 psi
with another�and often there�s no
way for the home handloader to
tell the difference.
According to handloading lore, a
basement loader should be able to
tell when pressures get too high by
such signs as hard bolt lift, or marks
from the ejector slot of the bolt face
on the head of the brass. But such
�pressure signs� (in actuality signs of
excessive pressure) were relied on
long before present-day piezo-electric
testing equipment became standard.
Older methods of pressure
gauging were relatively inaccurate,
older rifles weren�t as precisely made
as today�s, and some older brass not
as hard. Recent testing has shown
that pressure signs such as hard bolt
lift and, in particular, brass flow
into the ejector slot indicate pressures
ABOVE 70,000 psi. Modern
bolt-actioned rifles can withstand
pressures of 65,000 or less almost
indefinitely, but if subjected to
70,000+ psi loads continually they
will eventually fail�the reason even
the hottest American magnum
rounds have a maximum factory
pressure rating of 65,000 psi.
If you�re lucky, continued firing of
over-warm handloads will result
only in certain parts stretching,
rather than breaking. Headspace,
for instance, might grow because
the bolt lugs are stressed. If you�re
unlucky, the rifle�s action can come
apart all at once. This happened a
few years ago to a friend who was
fond of loading rounds beyond normal
velocities�and hence pressures.
He got lucky. The right side
of the action blew, sending the
heavy scope over his left shoulder
and into the side of a building over
30 feet away�instead of into his
face. HE OBSERVED NO �PRESSURE
SIGNS� BEFORE THE RIFLE CAME APART but had
been shooting hot loads in the same
varmint rifle for over a year.
What all this means is that we
should be very, very careful about
which primers we use. The safest
technique is to use the exact same
primer listed in the loading manual
for any load. Unfortunately, this
means stocking almost every primer
made, an expensive proposition.
Instead I generally start with either
CCI 200 (standard) or Federal 215
(magnum) primers in rifle loads.
Both of these primers are among
the mildest of their type so should
produce safe pressures. (No, Federal
215�s are not the hottest magnum
primers around. They were the original
�magnum� rifle primers, so
many handloaders still regard them
as the hottest. But recent tests indicate
both CCI and Winchester
make hotter magnum primers.)

Only if the loading manual lists
another primer do I try it if the
CCI 200 or Federal 215 doesn�t
produce the desired results. For instance,
many loads list either the
Winchester WLR or Federal 210 as
a standard primer. The Winchester
is definitely hotter than the CCI
200, so I use it only in loads where
it�s suggested.

I learned this lesson after some experiments
with pressure-testing. I�d
worked up a load in a .270
Winchester rifle that showed no traditional
pressure signs but had substituted
a Federal 215 when the
Federal 210 listed for the load hadn�t
produced the accuracy desired.
Then I had this load tested in a
piezo-electric lab. The average pressure
was almost 68,000 psi, well
over the limit for the .270.
Substituting either the Federal 210
or CCI 200 dropped pressures into
the low 60,000 range.
This is why most loading manuals
advise you to stick to the recipe.
Modern bullets can create far different
pressures than the fairly standardized
bullets of 40 years ago�but
switching primers can make even
more difference. Be careful!
