H4831sc in 6x47 Lapua?

[JustinP]

Gents

Seeking some technical advice. I've been shooting a 6x47 Lapua through a 1 in 7.5" Krieger tube with a .272" no-turn neck chamber. Loads of 39.2 to 40gr of H4350 with a 105 scenar on top and a 450 small mag primer are netting me groups of about 0.5 moa at 100m, reasonably consistently - but I just don't buy that I can't do better.

I''m thinking of trying H4831SC, which will fill the case more (can't be a bad thing) than the 4350. Has anyone out there tried this powder in the 6x47L?

All advice welcomed

Cheers, Justin

First I would try a different bullet and then some reloader 17.

I would be going the other way toward faster burning powder...Varget, Reloader 15, H4895...

I know this is not apples to apples but H4831SC in my 243AI gives better accuracy than H4350. H4350 gives more fps but H4831SC and 105AMax has proven the best.

I tried Viti 150 today with 115 bergers. The velocity was 3022 with under 1/2, 5 shot group. The spread was only 3fps. The reloader 17 was 3080 with about the same size group with 105's.
