I buy good inlines and use Blackhorn in them since it came out with out a problem.
I use GOEX in some guns I like Swiss better but find it very difficult to come by.
I use Pyrodex in my Traditional Hawken and Renegade rifles tried every thing available and for these guns I like it best, I use it in my pistols also.
What a person uses is a personal choice and is often dictated by circumstances.
