Rate of twist
« on: June 16, 2015, 03:22:28 AM »
Measured twist in my 48 inch .45 barrel for my current build and it looks like 1 in 54. Any one have any experience with that combination?

I am getting anxious to see what it will do. I don't get much time in shop so it is taking forever on this one.

In most calibres, twist is not critical - 40" to 60" to even 80" - all will shoot just fine in a .45 - IF, you take the time to find out what shoots well in it.  Usually the slower the twist, the more powder it will demand. Much depends on the ball and patch combination you use.

This fellow speaks with authority, I try to learn from him as I can.  His observations here echo everything I have experienced and choose to believe about ROT's.  

Work up a good load, forget the rate of twist, enjoy.  ;)

I agree with Daryl, at least in a 45. Years ago I had a percussion 45 with a 72 inch twist barrel. I am ashamed (and concerned about safety) to tell you the max load I loaded for hunting, it was in excess of 100 Gr of 3F, wonder I didn't blow the drum off! But the hotter you loaded it the better it shot. Contrary to many telling me it wouldn't shoot light loads it shot 40 grains of 3F very well.

Patching, anything I could get my hands on and still get the ball seated ;D
