Howdy Fellas!
I am a long time lurker and appreciate all the information you guys have here. Yes I am from the hated lands. I know I have a big hurdle to overcome LOL!
Anyways, I haven't seen much on this so figured I would throw it out for anyone in my predicament. Components for 300 PRC are somewhat hard to come by at least for me. I finally scored some Lapua 300 prc brass and I have some Hornady 225 ELD Match projectiles. The only powder remotely possible I can find is US 869(I cannot find any data on the forums from people trying this powder with 300 PRC). So I started my load workup today. It was 103 here today so the barrel heated up really fast and started to wander on a couple but I think I found a few good spots to look. This is from a Christensen Arms 300PRC Long Range Mesa shooting at 100 yards using sand bags (I have my flame suit on for the group sizes so bring it). I went in .5 grain increments just to look for pressure signs and I did NOT have any yet. The max charge listed by hornady is 88.1gr for 230gr projectiles and I was using 225's.
Again, it was hot and I feel a few of the third shots wandered if I went too fast. I think I have a few good velocity nodes to explore. At the very least this proves US 869 will work decently for 300 PRC. The 4 shot string is really a 3 shot but the SD and ES is amazing and I had 2 shots in 1 hole with the third shot wide right. I think it was because of the heat. by that time it was easily 100 and the barrel after 2 shots was hard to hold onto. Anyway I am going to start here at 84ish and see what I can find.
I hope this helps somebody. Please feel free to reply and provide feedback, good or bad I am by no means an expert and can use the help!
