It's 9:25AM on June 17, 2021, and I just got off the phone talking with Jason at Rice Muzzleloading Barrel Company.
Drop-in barrels for Thompson/Center rifles with 15/16" octagon & 1" octagon barrel channels are as follows......
Fast Twist.....
15/16"--.45 caliber, 1:20" twist
1"--.45 caliber, 1:20" twist & .50 caliber, 1:24" twist
Round Ball Twist.....
15/16" & 1"---.32 caliber, .36 caliber, .40 caliber--1:48" twist
Rates of twist can be changed upon request, most likely for the fast twist barrels. The round ball calibers are OK at a 1:48" twist.
There are NO calibers larger than .40 in round ball twist. Due to the depth of the screw holes used to anchor the underrib & underlug to the barrel. Jason got short tempered with me when I questioned him on why no .50, .54, or .58 calibers in the round ball twist in the 1" barrel.
Rice is currently using the flint breech plugs, such as Track of the Wolf sells for breeching a barrel to fit a Thompson/Center tang if someone wants a flint barrel, instead of a percussion one.
Plans for an in house, CNC machined, flint breech plug are in the works, but no idea how long before it will be available.
Because of the recent upswing in steel prices, the cost of the drop-in barrels has gone up.
Fast Twist = $475.00
Round Ball Twist= $395.00
Sorry about the incorrect info on prices that I posted recently, but I was unaware of the price increases.
Edit: I was really disappointed at the lack of the larger calibers in the round ball twist barrels, which was my reason for the phone call this morning. I was hoping against hope for a Rice 1" octagon, .58 caliber barrel with a 1:48' twist. Not to be. Then, accidentally, the flint breech plugs got introduced into the conversation, and I was REALLY disappointed. Then, Jason mentioned that they were going to be CNC machining their own flint breech plugs eventually, and I was REALLY, REALLY disappointed.
Edit 2: I forgot that the depth of the rifling for the Round Ball Twist barrels is 0.010"-0.012"
For the Fast Twist barrels it is 0.004" deep.
