The simple version,  just like bigger tuna fishing on a cattle boat west coast style   heavier leaders tied to 100 lb to 200 lb quality braid main lines depending on how far south  you are,   best quality heavy gauge sharp ass hooks / big lively bait = big fish, even fishing the kite  using dead flying fish as bait slapping the water for old mr. tuna.   Same with guns.  big heavy bullets =  bigger game with roughly similar powder / case capacity, running at roughly same pressures.  Couple months ago we were fishing for larger Ca bluefin tuna ,  broke off 400# test mono leaders the local tackle shop crimped for some guys,  I rig & crimp my own I don't trust others to do my rigging,   only one 180 lb caught by another guy on the boat, the rest were much smaller fish,  guys broke off some large ones because most were rent rods,   got to be rigged correctly and the right gear for the big stuff when you are fishing on a big cattle boat that can't chase the fish,  basically these big boats are stationary and can have  multiple hook ups at the same time.  Same can be said about choosing the right caliber.  the 338 win mag gives you a little more extra margin of error for those big animals especially under less than ideal conditions.

I've harped on this for I don't know how long .  manufacturers need to think outside the box.  Don't get me wrong innovation and new ideas spark my interest far faster than a new twist on an old platform / subject or has already been done before in the past,  people just may have never heard of it that's why we have some many wildcat cartridges out there that fell by the wayside.  Granted we do have improvements in bullets and powders along with ballistic & optical equipment that extends the shooting ranges.  In this day and economy it better be far far better than what's already available for me to lay down the cash on something I more than likely don't have a need for or already have something similar that does basically the same thing.  Manufacturers are peeing in the wind as far as I'm concerned along with throwing valuable assets and money into products especially on the gun/ammo side that hold little to no real super advantage over what has already been made or has been done in the past, and in todays world components and hardware may or may not be readily available to the public in any great amounts.   Timing is everything I think in a crowded market.  Just my opinion companies need to do what they do best in a very good quality product in the short term and  continuing,  but in the  long term  get idea people in there and start thinking, inventing new better more efficient ways of launching projectiles.  then I might be interested.

I don't think Weatherby Mark V's are niche guns,  it's a gun it's a tool to be used like most other guns,  it's just going to take the right person at the right time just like anything else for someone to buy it. 

Dino you can try e-mail again had it turned off.   I'm pretty sure the problem is on my computer allowing access to pictures.  I need to take it into a computer person so they can correct problem.  thanks

If it were me and didn't want to blow it to pieces I agree a good 22 mag with a heavier bullet would be my choice,  our season is just sky of 8 months long and we do call them although some people trap them for their pelts.  Every one I have shot with a centerfire has been ugly, the other way some of my friends have been doing is with a shotgun / rifle over under along the lines of the old savage 24's or Baikal's  12 ga / 223 or what ever you can find, scoped for longer ranges and just sight down the barrel for in your lap calling distances,  saves carrying 2 rifles when calling in varing vegetations, mostly in our area for fox.  Yes they will come to a call if you are patient and sit there for longer periods without getting winded or moving.  I had an old wooden Lohman wounded rabbit hand  call that works, gave to my son,  still have a small old cassette player that I recorded myself using different calls ,  they both work.   Guys trap them and more successful.   shots guns are great for closer in shots and won't tear them up so bad to where the hide can't be repaired as long as you use the right shot size and don't shoot them too close.  that's assuming you can legally use a weapon / caliber/ ammo / shotgun for bobcats or whatever animals in your area.     hope you get a few. 

Looks like a wonderful hunt, congratulations

Unfortunately there are a lot of a-holes out there,   we are not allowed any geme cams used for hunting public lands in my state that electronically transmit back pictures to another location,  new law here.  we could go to any of bunch of different G&F trick tanks and find a dozen or more games cameras set up on the fence's,  it got stupid so G&F and hunters got tired of it and disallow games cams for hunting, now you can still use them for photography and be legal,  yea like that is going to stop people from using them for hunting.  Anyway if it were me I would set up multiple hidden cams and catch the sucker and turn them into the authorities.
