I had a 700 VLS tuned up by a local gunsmith who put a Hart 5 grove 10 twist and a Bushnell 6500 mil dot. My fireforming loads were lite and pushing 85g Sierra boattails. They shot inside 1 MOA @ 200, I was impressed. I tried 87vmax, 90 Siroccos, 95 SST, and 105amax with a variety of different powders. The 105 were all over the place and the 95 were not a whole lot better. The 90 shot really well as did the 87's. The load I settled on last year was 44.5g H414 pushing the 90 Siroccos. They shot inside 1/2 MOA @ 400 with this load off the bench. I plan on running them through a chrono this week, but am finding myself wondering if it's worth trying to improve a load that shoots pretty good already? Any advice, tips, or pointers would be appreciated.
