Any big bore shooters?

I can't give you an answer on practical range because I've only shot it at paper out to 100 yards so far. I only shoot my 458s out to 150 yards and I suspect you could gain another 100 yards with the 375. My primary interest is building the rifles and setting at the reloading bench and shooting bench doing load development. Normally when I come up with what I feel is the best accuracy I can get out of a gun, I get bored with it and move on to another gun project. I just happen to like doing it with big bore guns. I do hunt with them but that is secondary to my interest in load development. As far as the question of expense, it will be cheaper to shoot the 375 than the 458 due to the cost of bullets. The brass and primers are the same. You will use more powder but that cost is fairly insignificant to me. Coyotes are the only thing I hunt on a regular basis any more but I am planning on doing a hog hunt at some point in the near future so I can see how my 458s and 375 work out on them.

Buddy of mine just put together a 50 Beowulf with Anderson parts. I believe it has an 18" Barrel. We have shot factory loads with it and it shoots well. He got dies and brass and we have been tinkering with loads right now.

So far we have tried H110 and Lil'Gun with 325 Speers and 335 Rayners. I have not ran it across chrono yet, or really shot paper but just tinkering around shooting some AR500 plates it seems to be effective with just the EOtech and factory trigger at 100 yds.

I did have a question (Not to hi-jack thread). I found a bunch of brass and set of LEE dies for him. I initially did the reloading for him, as he did not have a press yet. I was having a BEAR of a time re-sizing this stuff. I would lube them and everything and still it was a night mare. Majority of the brass was new (I like to resize and new brass minus Lapua just in case). The once fired brass I receive was impossible to resize. I actually stuck 8 cases in die. Now I have not tried resizing brass fired out of his gun yet to give a good comparison, but I was just wondering if this is a common issue or if I have something out of wack? I know these cases only have a slight taper on them for feed, which is why I was some surprised. I have never had straight wall cartridges be such a pain.

Also, with this round being so new, there isn't much load data out there. I have just been going off the Anderson recommended loads so far. Everything has been good. Just wondering if anyone had any recommended loads.

Thanks
 
what kind of lube are you using? i resized a bunch with hornady one shot - easy peasy. this was all once fired stuff straight from alexander arms.
 
If you haven't already tried it, do yourself a huge favor and buy a tin of Imperial Sizing Wax. That is the only lube I will use on my big bore cases.

That's true, but you gain 3000ft/lbs + muzzle energy in exchange for your limited range. Sometimes you just need to make a big ragged hole through something, not pick off gnats at 600 yards.

I just find my 260 Remington AR10 does what I want it to do with a 140 grain bullet at any range that is needed to shoot pigs/deer/yotes/etc.. I don't have to wait for them to get into a certain range to be able to shoot them. If I can see them,I can kill them with it.

I was using Lyman spray lube. Same stuff I use for everything. I did just run out and picked up some one shot.
 
with one shot, i find it really pays to make sure you let it dry competely before use or you'll get some that feel tough going into the dies. this applies for all calibers FWIW.

i spray them in a plastic shoebox (the $0.98 walmart delux jobs) shake around, spray some more, etc.

its nearly impossible to over lube with the stuff, so dont try to be cheap with it. if they're feeling sticky in your die, spray them again and wait a few mins.

you should get several thousand cases lubed out of a can, even when using it fairly heavily. i typically see 2500-3500 cases per can on average.
