im looking to get into the world of BP and was looking at two budget guns. i was wondering which would yeild the greatest accuracy : one has a 34.5 inch barrel with 1 in 66, and the other is 28 inch with a 1 in 48. whats more important with these things? length or twist :-M

I'm no expert, but I believe it depends on if You plan on shooting patched balls or some of the more modern type of Bullets. Bob

It depends on several things, caliber for one and what you plan to shoot the other.
Smaller calibers tend to like 1 in 48 or less. I have a .40 with a Green Mountain barrel that is 1 in 48 and will shoot a cloverleaf with patched balls at 50 yards even with my old eyes that can't see the sights. It will not shoot a bullet type projectile worth a hoot.
TC guns .45 and up are 1 in 48 and will shoot patched balls and bullets well, they also have shallow rifling. The TC pennsylvania hunter guns are made for patched balls and are 1 in 66.
For .45 and up 1 in 66 will handle patched balls well but not bullets.
-
It also depends on how deep the rifling is groove to groove. The deeper rifling is probably a flintlock and will do rather poorly with bullets. Also consider which rifle you are comfortable handling.

Eric,
Do you know of any Green Mountain .40 cal drop in barrels that might be available?
-
Barrel manufacturers make all their barrels the same as far as lands a grooves go, same for rifling depth. If you chose to use the barrel on a flintlock or percussion gun the barrel will be the same.
A .40 drop in is pretty rare, I saw one on ebay a while back and the guy wanted somewhere around $350 for it.
I understand Rice Barrels has been talking about making a drop in but don't know if they have or not at this point.

Barrel length is not going to matter unless you are looking for a longer burning charge. Like using 2F over 3f and the amount of powder
1:66 is a round ball only twist and does it well. Sabots can get unstable as they don't spin enough
1:48 is a modified and can shoot slugs, sabots and round balls fairly well
1:36 or there about is what inlines use as the faster spin is better for sabots and slugs

I did a search and found a year old listing for a .40 drop in.
Green Mountain .40 drop in barrel, 1-48 twist, percussion, blued, 1" across flats, modern 'primitive' sights, 29" long, fits TC Hawken and Renegade with 1" barrel channel. Purchased it as unfired, never have used it, looks new. $250 shipped in the US.
