trying to find a barrel

[eseabee1]

Ok Now that you all really got me confused on inletting the tang and breech ( just kidding very helpful infromation was given ) I am looking at barrels I know what I want but is it out there and I am just missing it ..My build I am planning on doing is a Southern mountain just a plain stock nothing fancy but I want a 40cal 44" long with a 1-60 twist all I seem to find is 1-48 as I will be doing nothing but patch and round ball I perefr a lot slower twist rate any suggestions ?

  Hi eseabee, I'm just curious, and interested to know why the slower twist? Just thinking out loud here so forgive me. Now won't a slow twist take a larger charge to get it to shoot the most accurately? Therefore you should get awesome velocities, but I think you may need deep grooves also, round bottomed and narrower lands then grooves. My experience is with a 48" twist in a forty. Gosh,it shot good! 7/8 by 38"rb'd  Rice. It shot better then I could hold.That was with a 50gr charge of 2f. So my curiosity is perked with your inquiry. I once thought a 1 in 56" would be a nice twist in the 36 to 45's, but have never had one. I haven't seen that twist offered much, but that may just be me.

I had one yrs ago that had a 1-60 twist and it was great to shoot very accurate I shot 40grs 3f and Well couldn`t find a better rifle but I outgrew it and then my mother was shooting it then when I went to the military it was sold ..I don`t know to much about twist`s and such I just know what I had and liked if a 1-48 will do the job then great that is why I am asking questions ..I had a 54 with the new gain twist in and it shot great just wasn`t happy with the gun itself spent alot of money and didn`t get what I asked for ..so this time around if I can`t make it I will get the parts and such and have someone make it for me ..

Rice will do a slower twist, just have to wait longer.  Call them and ask.  You may get lucky and find them running in the near future.   They are pushing hard to get a head before they move this winter.

Esseebee...........why not a 1/48" twist, it works.   My favorite shooting gun is a 40 and it has a 48" twist, won a lot of stuff with it.   I had a friend who shot cross-sticks at frindship.    He wanted a 40 with a 72" twist.   We did make him a
barrel as he requested, and it did work.    He shot 80 grains of FFF in it.   I just wanted to show you that a slow twist will
work OK, but, it will require more powder to get the potential accuracy out of it................Don

Wondering what size barrel that long?  13/16   7/8   15/16?  Careful you don't get her tooo muzzle heavy.  Been there!

My .40 has a 48" twist and it loves 65 3F or 75gr. 2F. Taylor's .40 has a 48" twist and he's shooting 65gr. 3F in it.  48" IS a proper RB twist in .40 cal.

A 48 twist works fine to at least 50-54 caliber.
Current Green Mountain 40s are a 56 twist I think. Though why they thought it necessary to change it from 48 I will never know.
There is a lot of BS and myth around about round ball twists. Most of it stemming from 48 twist barrels made with shallow "naked bullet" rifling and peoples attempts to shoot PRBs in them. This experienceh as no bearing on a rifle with .008 to .012 grooves and a 48 twist.  
All original Hawkens were 48 so far as anyone knows.
But people have the notion that 48 is too fast. It is not and in fact for most calibers in use by moderns it may well be the best twist.
In calibers over 54 a 66 or 72 might be better and over 58 I would not want  48.
But then the old Douglas 66 twist worked fine in everything they made....
But a 40 would likely shoot good with a 36 twist.
Basically in barrels rifled properly for a cloth patched bullet almost any reasonable twist is as good as another only the extreme ends of the spectrum would be problematical. A 96" twist 69 caliber is OK but a 96" 32 might be too slow.
