I'm using the 25 gr Berger Varmint HPs, part 70308? It's whatever one they still make. Everyone says the discontinued match 25 gr were the best, but these work just fine for me. I'm pushing them around 3900fps under 24gr of IMR 4320 from a 24inch barrel. I hunt almost exclusively at night with thermal so my shots are almost always under 200. Most of the fox are inside 75. I almost never get any kind of exit on the fox and if I do it's tiny shrapnel, not a blow out.
