I have a NEF 45-70 that I have been shooting 300g Hornady HP's at 2000fps with 48g of IMR-4198. Accuracy is surprisingly good, about 1.5" at 100 yards. I figure this is a good load for plinking, coyotes, deer, and maybe black bears?? Anyways, from what I gather, you need at least a 350g bullet for elk. I was going to go out on a limb here and try something like some 500g TSX bullets or something. I just want them for elk mainly. Would certainly put the big hurt on both ends, lol!! I tried getting the bulk Remington 405g SP's but everywhere is back ordered. I dont know of any other 400-500g lead bullets, besides Swift A Frames, or the all copper Barnes X bullet, both of which are about $1 bullet or more.
Anyways, I'm not real familiar with the big bores, just kinda always wanted one for the fun of it mainly. Slinging a big chunk of lead is actually quite fun. Can I use those big 500g Barnes TSX bullets in the 45-70? I dont think there would be a problem, but then again, i'm not 100% positive. What would you guys use for up close elk out of the big Govt?? Thanks for any help and or advice.
If your throat is really long, maybe. Those 500 grain TSX's are loooong, and you don't really need that for elk. Don't the 45-70 would have enough velocity to expand it well, but I may be wrong. Why not a lighter TSX, or a 300 grain Partition? Or a hard cast bullet.
The guy that turned me on to 45-70s has killed two elk with his.Both with 300 gr. rem, hollow points and 52 grains of 3031 and it flattens em,also many deer and they die in their tracks.Bi-Mart used to stock Speer 400 gr fps here in lebanon Orygun but the last time I was there they did not have them so I bought Hornaday 350 gr fps.57 grains of IMR 4198 gets me 2137 fps out of a 20 inch barreled ruger #1.H4198 is supposed to be a little faster according to Hodgdons website.I think you can safely push a 300 grain pill at 2500 fps out of a modern single shot with it.I,m not sure where your NEF rifle is as far as strength is concerned.Anyway those kind of loads will at, reasonable ranges, will knock the sap out of mister blue mountain bull elk.I hope you get to find out!Take care,GRPB from oregon.
I used to have a Marlin 45-70 that shot fairly well (for a lever . I was able to push a 400gr cast bullet to 17-1800fps with acceptable accuracy- definitely kills on both ends though!
I would say any reasonably tough bullet from a 45-70 will do just fine on Elk. I would not fool with the Barnes bullets in that caliber because they are so darn long you lose too much case capacity. I had to give up a lot of velocity to be able to shoot them and I didn't think it was worth it. Accuracy was nothing special, and the big carp mouth hollowpoint kills the BC.
I cast my own lead bullets and they performed very well on game. My second choice was the 350gr Hornady JFP. They shot well too.
