I'm glad this thread got revived. I recently switched to 869 in my 300 rum, I was seeing pressure signs before I got to the velocity that I thought I should be getting. My load is almost the same as yours varmint hunter, it's 101.5 gr and fed 215 primer 210gr smk, velocity is 3175 with es in single digits. It has no pressure signs at all after first firing the primer pockets were as tight as the virgin brass. Shoots a hair over 1/2" at 250 yds. I can't wait to stretch it out a little. Right now all I've got is 250 there is a range not far from here that has 600 but I'm not a member yet so that's on my to do list here in the next couple of weeks.
