6BR Short Barrel Powder

[Old Navy]

I am in the process of building a 6BR specialty pistol. I cut a barrel back to 16.5" and ran my favorite 107 SMK load across my Magneto Speed. I was using 30 grains of Varget and 450s. This load clocks 2913 out of my 28" Critorian 1 in 8 barrel. The same load does 2693 out of the 16.5". I would like to stay with the 105 class bullets. Is there a better choice of powder for the short barrel or should I just leave well enough alone?

H335 might get you a bit more speed out of a short barrel.

H-322 and H-4895 both work very well in short B-R barrels, and are the powders I use in mine.

Accuracy first. I got lucky my 6BR rifle and pistol both liked the same loads, as did my 308.

It has been my experience that the powders that work well in my rifle barrels work in my 14 to 17 inch barrels the best. I will usually try 3 to 4 different powders before I choose one.
