PS the gun was free and came with NO paper work as far as cleaning and fireing. I know i need shotgun primiers(of think i know) to be able to fire it.
Call Thompson Center Arms on the telephone 1-603-332-2333 and tell them you need a manual for the Renegade. They will send you a small book filled with load data, step by step instructions on loading, shooting, cleaning, etc. Also it gives you some excellent loads to try in the rifle.
Also you do not need shotgun primers.
You need #11 caps. Unless that rifle is sporting some fancy nipple it should have a #11 nipple on it. Look for RWS Dynamite Noble 1075 or CCI Magnum #11 caps. I have had terrible luck with Remington (although they claim they have made them hotter now) and the CCI #11 (non magnum).
No pellets with that rifle. Shoot loose powder only. The rifle will shoot any band of loose powder you might want to use. For now, I would get some 2f grade powder and start with that. Further down the road if you want, you can shoot some 3f grade powder. Also if you shoot loose Triple Se7en 2f powder, it is 15% stronger then normal powder so adjust your load accordingly. Black Mag is another strong powder. Some one said to cut that at 20%. I am sure a dedicated Black Mag shooter can tell you more.
So you will need some supplies to get yourself started. I own four of the .54 Caliber Renegade (one of my favorite model rifles) and all of them are great roundball shooters. I shoot a .530 roundball. Hornady or Speer are good. Also Buffalo Bullet Co. makes a good roundball. You can also cast your own if you have lead and molds.
The roundball normally shoot well with about 90 grains of 2f grade powder, a .015-.018 thick patch and ball. I lube and cut my own patches but you can purchase pre lubed Ox Yoke .015 patches for the rifle and they will work real good for you.
The rifle also shoots conicals very well. R.E.A.L. 300 grain conicals will shoot real good out of them. So will ball-et, and maxiball. If you would like a list of the things you might need to get started, there was a post covering that back a ways, or PM me and I can send you a list...
Good luck with your rifle. You have a GREAT RIFLE...
