I fooled with a lot of Trailboss when it first came out...it was always adequate but never the best. One mans's opinion. 4198's or RL 7, but most of my experience is with .30-40, '06, 8x57, 32-40,38-55, 45-70.
You might keep an open mind on 'fast' powders, sometimes if your bullet is a tad small for your throat/groove, you can save yourself the heartache of leading with a swift kick in the ass with fast powders and perky primers.
Again, one man's opinion.
