I have a traditions Lightning with a scope that shoots very well out of the fast twist barrel.

But heck I think any of the 45 caliber rifles are good.

You can keep the load low with an inline as well as a sidelock, the rifle I mentioned I shoot with 80gr 3F or 80gr 2F loose and recoil is very light. I have not even tried the rifle with pellets. To be honest on the sidelock in 45 I have been away from what is on the market to know what is out there. My daughter who is recoil sensitive shoots a Traditions Deer Hunter Scout in 50 cal, with either a 490 round ball, or 300 grain conical pushed with 80 grains 3F.
