Re: .260 and RL 22.. Anyone made it work
Sorry to bump an old thread, but I've been looking for info on RL-22, how it works with the 260, and I've read a lot of conflicting reports about its temperature sensitivity. I tried H4831sc under 129gr SSTs in my 20" Model Seven and wasn't thrilled with the velocity. RL-22 gave me 350 fps faster velocity and a 3-shot group at 100 shrank to 0.174". I know this wasn't with 140 gr pills and it's a walking around hunting rifle, but I was surprised that I got a 2,897 fps average out of that tube.
