I'll preface this by I'm new to reloading and I like think I did my research but I just don't know where to go next. My rifle is a stock Ruger Precision Rifle, 24" 1-8 Barrel. I am using Hornady brass for these tests that was originally factory that I fired in this rifle only. As far as brass prep, I clean, Deprime, FL size with a .002 shoulder bump (from a fired case using a redding non bushing die), trim to 1.910, and chamfer/debur.
I did follow Erik Cortina's method for finding jam and measured that at 2.905, so I seated the bullets .02 off of that for 2.885 COL. I made this change after the first two rounds of load development. So I'm sure that could have some effect on my group size, but I was out for more details on MV, SD, ES on that third test because I didn't track those in the first two like an idiot.
The 39.4 load seems pretty promising it was very flat just a bit wide, same with the 40.1. The 41, I highlighted in red because I feel like I just shot terrible. The third test was also 5 shot groups instead of 3.
The ultimate goal for this load is 1000+ Yards. I'm not really sure where to go next. I have zero signs of pressure and the brass has been fired 4 times. I was contemplating between trying seating depths on some of the low SD nodes or seeing about going higher in charge to get closer to 2750 MV. I'm concerned about the velocities knowing I want to go out to 1000 or more. From my ballistics app the 39.4 should still be 1300fps at 1000 but it makes me nervous with my limited knowledge. Hornady has 41.5 listed as the max for this bullet and their cases.
Appreciate any insight you all have. I also have 100 factory new Hornady brass that i could load up and completely restart if you all think its a good idea.
