Im in the process of working up a load for deer this year using my savage model 10 predator 22-250. It has a 24" 1 in 12 twist barrel. I have 4 loads Im going to test. The first is one Ive had for a couple years now. Its a 60 grain sierra tmk over Cfe 223. The next three bullets are the 62 and 65 grain sierra gamekings and the last is the 70 grain speer round nose. Im gonna try the heavier three with Superformance and then do a video of all the accuracy and speeds and hopefully take a deer with each this season to see how the perform. Cant wait to try them all out.
I've killed 14 deer with my 18" SPR AR using a 65gr SGK right under 3000fps with a max load of AA2520 from 40yd to 170yd- several were large for our NC deer. About half of them were bang, flops... a few kicks and that was it. The others were bang, flop, get up and stumble 20 yd and expire, and only 1 was what you'd expect when you shoot a deer w./ a high powered rifle- bang, Thwaappp, buck, take off running whatever direction they were pointed leaving a very nice blood trail and dead in 50-60 yd.
Something about that little bullet- I discovered it was designed with a thicker jacket for hunting Kangaroo's in Australia I believe I read. Anyways, I cannot believe the impact that that load/ bullet combo has on deer. The biggest one was a nice 7 pt and about 170 lb at about 80 yd as he was rubbing a tree- tree was moving, no wind and it took a while till he moved in an opening thru the trees so I could thread the needle so to speak, shot right at dusk and I heard very loud crashing around, By the time I climbed down out of the stand it was dark , I didn't have a flashlite- my bad- so I used my cell phones lite. When I found him it was amazing what that little bullet did- perfect shot behind front shoulder- bullet must have hit part of the shoulder as it was all "jacked up" front legs cross in a very weird way, both shoulders broken, a piece of the bullet went up and broke the spine and the rest of it exited with a pretty amazing exit hole. That was one of the Bang Flops for sure.
Its not my "go to hunting rifle" i usually use a 7-08 w/ 140 gr ballistic tips, but when Im just filling doe tags at the end of the season, I grab my ar.
Just my experience over about 5 yr of using it for that purpose.
