Good groups bad numbers

Hows the ignition working on that savage? How does each dry fire sound- does 10 in a row sound exactly the same snap?

It does. Never an issue. I backed the bullet up to .020 off the lands. Thing are better and tried big game powder. .1 grp and single digit es. Im good with it now

New 6XC giving me a bit of a fit. Been testing different powders with Sierra 85 gr BTHP for varmint hunting. Ive been getting groups as small as .1" but my ES/SD aren't that great, ES varying from 15 fps to 100. I have not played with seating depth yet. Brass is twice fired Peterson. Testing 3 other powders today and then decide which powder and then seating depth tests. Bumping shoulders .0015 and necks over a mandrel, scope is a viper pst, rifle is a savage 110 sa with preferred barrel blanks 10T 5R barrel. scope and action screws good. I have several great groups but the numbers aren't great. Tighter neck tension? Seating depth? I've always been told that good numbers and bad groups can be corrected with seating depth and the reverse fixed with a powder change. I've tried 10 powders in this rifle. Dropping back and rethinking this. Frustrating

I’d put it on paper at distance. If vertical spread is tight at 500 or so, the chronograph numbers don’t really matter.
