I tried 70 gr. VLDs in a 14 twist, not expecting much and they were all over the place. Should have known better.
I killed a 200+ hog with a VMax 55gr, head shot, stone dead. But Nosler 55 Ballistic Tips are a bit more solidly constructed than most and that would be a safe bet in a 22-250. I don't know about the 60 grain requirement, seems a little bogus, if you ask me? The Sierra 63 gr. semi pointed is a very good, reliable bullet and one I am currently using in a 220Swift that has some throat erosion, on coyotes, primarily, but I am quite sure it will work well on mule deer, if you do your part.....lol.
Berger has discontinued the 62 gr. target but you can still get the 64 gr. that I have use extensively on bobcat and coyote. On a side presentation they usually exit without expanding, but kill bang/flop, no runners. Honestly, have not tried the 64 on deer, but if that's all I had, I would use it with a fair degree of confidence. Full disclosure, my 22-250 is an Ackley, considerably faster than the plain vanilla Remington. BB
