"Best" powders for 77 grain sierra hpbt?

[Maverick1911]

I am sure this has been posted somewhere...but, I am interested in hearing powder choices for the 77 grain sierra hpbt. I am going to be shooting out of a 20 inch hart barrel with 1:7 twist, if that matters.. I have used H335 because it meters very well in my hornady LNL but have heard that some don't prefer that powder? Any preferences?

I cant help you anyway but you didnt say what caliber. Assuming .223.

AA2520 is awesome for heavier bullets in .223. Ramshot Tac is a second choice. Both are ball powders that meter extremely well in progressives. The AA2520 provides sub minute accuracy with the 77 SMK in my White Oak barreled AR.

Tac and Varget are my favorites

Has anyone worked with CFE 223 with the 69g or 77g Sierra Matchkings?
