Re: Rem 5r 300WM - 215 Berger Hybrid Velocity??
Listen to what Broz says, he helped me get started with my load. I'm using Redding dies. I full length size everything I shoot. Odd thing is that everyone of my rifles (.260, 7RM, 300WM, Edge) all shoot better when I take the expander ball out. I'm not going to over think it. I also tried 74.5 and 75.5 grains, but 75 seems to be my sweet spot. Kirby Allen had a post on here some time ago about load development. He advised to work up until you see pressure then back it off two grains and that will probably be where you're sweet spot is. I loaded up 3 of each load from 74-78 grains. I then shot one each of 74, 75, 76, 77 letting the barrel cool between each shot. 74-76 grouped in 1/2 MOA and 77 jumped out of the group and had a slight ejector mark. Didn't shoot 78 grains. Repeated this 3 times and had same result each time. I took 74-76 out to 750yds. to see how they grouped. 75 was best with some vertical. Loaded up 74.5, 75, 75.5 and took them out to 750 yds and 75 was by far the best . All three were within 1/2MOA vertical of each other. Figured 75 would work. So in this case Kirby's theory worked. I've never worked loads up this way before. Not sure what my ES is and don't really care. I will see what it does at 1000yds. and hopefully won't have to tweak much. I'm really only looking at this rifle to go to 800, any further and I'll just grab my Edge.
