I re-read some articles on the .280 and discovered that Boddington likes either 4350 powder and same for Barsness.
So I rustled up 6 loads of 160gr Accubonds with 51gr. H4350 as published max. Oh, oh, the velocity was 2646fps but two consecutive three shot groups were very much less than an inch.
I will creep up to a 2800fps type threshold and see what the paper looks like.
