Gents and Madams,

Any recommendations from personal experience as to most desirable twist rates that can be used in rifles chambered for .45-100 (Sharps 2.6").

Any reason why an existing 1-18" twist (rechamber) will NOT be appropriate?

Objective is distance shooting out to 1000 yards/meters.

Bullet most likely will weigh 535 to 550 grains.


Thanks for sharing.........

Barrel Twist

Windcutter--The 1-18 twist is the way to go in a 45. I have a 45-90 in 1-20, and a couple in 1-18. Beyond 800 yards the 1-18 consistently groups noticeably better than the 1-20. Out to 600 yards the difference is there, but it doesn't seem to be as pronounced.

Rechambering an existing 1-18 to a longer cartridge is the easiest route to take. Shoot straight, rdnck.
