Just use what ever you can find the cheapest.
Pete,
The longer I am involved in this traditional B/P thing, the more I believe
your right. At least for myself, unless you really want to split hairs I find very little difference
as far as accuracy, from one brand to the other. If there is a somewhat advantage
it would be in cleanup from one to the other. For the last 12+years I have stayed with
3fff Goex exclusively because it is available,about as cheap as anything else around.
Oh,and one other thing when I mailed a letter asking for promotional items for my
local gun club,hats,patches, decals etc.....They were kind enough to send
a box of items.
