So, working with my Colt.
First up I wanted to retry the 53gr VMax load. to see if it was consistent. It turned out to not be so impressive:
Next up I started working with 55gr Ballistic Tips. Expectations were that I might find better accuracy at somewhat lower velocities & that proved to be the case.
My typical shooting pattern is center, top left, top right, bottom left, bottom right.
This target was W748 / Federal 205 primers, starting at 24.0 grains to a max of 26.0. The first load (center) at 0.418" got my attention, I'll be shooting more of that to see if it repeats:
N140, 205 primers, from 25.3g to 26.9. I'd hunt with any of this, so will be revisiting it again to see how it holds up:
Benchmark, 205 primers, from 24.0g to 25.6. Looks like 24.0 - 24.5 works well with this bullet, so will be revisiting it again:
Last, I tried H4198. Not only was it not as accurate, I had feeding failures with all 3 charges:
