Went out and shot my 338-06 AI again this morning. I was happy with the accuracy of my loads with RL 15, but felt the velocity was lacking a little bit. Today I tried out H4350 and IMR 4895. The target on the left is from 2 loads of the H4350 and the one on the right is from the top load of 4895. I used CCI 200 large rifle primers, R-P reformed 30-06 brass, and Hornady 200 gr flat base bullet. Seating depth measured with Hornady bullet comparator off of ogive at 3.655. All 3 shot groups.
62.0 gr-2771,2745,2752 fps group size-.780 inches
63.0 gr-2821,2788,2783 fps group size-.800 inches only 2 holes from 3 shots
64.0 gr-2816,2809,2786 fps grous size-.480 inches just starting to compress load
max in my rifle
57.5 gr-2856,2865,2858 fps group size-.400 inches
58.5 gr-2898,2928,2904 fps group size-.810 inches
59.5 gr-2961,2944,2950 fps group size-.520 inches avg fps 2951, only pressure sign was primer not all of the way rounded, but not flattened. This is the target on the right.
I will use this as my hunting load, I think it will cleanly kill deer and elk out to 300 yds.
