If the barrel is 24" long and your ramrod turns more than a third of a revolution, you probably have a 1:48 twist. As far as I know, they came in 2 twists, 1:48 and 1:twentysomething. It's hard to judge exactly.

If you get the ramrod in the barrel some short distance, then measure up the ramrod say 12 inches and wrap some tape at that point, you may get a more accurate reading on the amount of twist you can observe as you push the ramrod in for that measured 12 inches. Then multiply by 4 to get the twist for 48 inches. My guess is you will come out to a number close to 1. If you do, its 1:48. If your number is close to 2, then its a 1:21, or 24, or 28 or whatever other rate they used.

1:20 is what it says for the White Mountain. That seems fast twist to me. Chap

RE: tc white mtn carbine
 

I think during their rein, the rifles came in 1-20, 1-32, and finally in the late models 1-48 twist. I have noticed that chart is not 100% accurate.

The dealer told me it had a fast twist too. I guess he didn't bother to check it either. I currently have an email in to the folks at T/C to confirm it butI believe that it is 1:48 as I checked again this morning using UncleNorby's more precise method. That being the case I am curious. As a newby to the sport what I am hearing is that a slow twist is more conducive to prb accuracy whereas a fast twist favors the conicals & sabots. If that is correct then where does 1:48 fit into the picture. Is it middle of the road as in jack of all trades / master of none? I think I see a fair bit of "homework" on the horizon.

RE: tc white mtn carbine
 

The 1-48 twist is a "do all twist." Some claim they do all, but none of them very good. That is far from the truth. Normally they are excellent roundball shooters, and very good conical shooters as well. Some are even shooting sabots with some exceptional accuracy from them. The biggest thing is you have to try different things and play with powder charges, etc. But once you find what the rifle likes, they are good shooters.

My 1-48 twist when shooting roundball normally tune in around 80-90 grains of powder with a .490 ball and a .018 patch. When I shoot conicals I find a bit lighter charge of 70-80 grains gets better results. Also the addition of a bore button or wonder wad seems to help in some cases. There are some projectiles you will discover that your rifle just will not shoot, no matter what you do. All you can do is remember that and not load those again. And never underestimate the power of a roundball. They make an excellent medium to short range projectile for large game. Place that ball in the right spot and you have made a 1/2 in hole through vital organs. It don't take a doctor to know what that means...

I bought one of these guns for my wife years back. It's a lot lighter and shorter than my Renegade. I think it has a 1:48 twist. It shoots 370 gr maxiballs over 90 gr Pyrodex RS very well. I put a peep sight on it and 2" at 50 yds is the average. The only other bullet I shot out of it were Lyman REALs, and they shot acceptably with a little less recoil. Never shot a round ball or sabot.

If the Renegade were out of commission during the season for some reason, I'd grab that gun and hit the woods without hesitation.

Thanks UncleNorby. If It ever gets warm or just quits snowing every weekend I would like to have a long getting acquainted session with my new toy. I tried it out 3 weeks ago but it was so cold that after 3 shots my fingers wouldn't cooperate anymore. I may just have to go to the local indoor range and stink the place up a bit.

My White Mountain Carbine has the 1:28 twist. They probably made a few different barrels.
