With H4198 I'd suggest a powder positioner. A small tuft of Dacron fluffed out is all it takes. Just enough to hold the powder against the flash hole - about 1gr. I'd try it with 20gr and 25gr powder. Don't underestimate the pressure being developed by 26grs. It may be enough to distort the bullet which would kill accuracy - depends on alloy strength.

I should mention that I use H4227 with 205gr plain based bullets (paper patched). I use wheat bran as a filler and get very good accuracy. It's a pain to get into the case but several others have reported accuracy improvements when all else has failed. Do you get leading in your bore?
