I gone and got a CVA Optima.

[YZ-80]

I got in the Bull at 100 after sight in with a clean bore and for fun, tried at 200, just one shot. The scope is calibrated for a .35 Rem w/ 200 grain bullet so I held on the bottom subtention and was off 2" on the windage and 1" low. I'll take it!

What powder are you using? With black powder and pyrodex I used
hot soapy water. Dried it out and put a coat of bore butter in the barrel.

I still use bore butter with anything corrosive. My old TC Hawkin has never had anything but dawn,water,and bore butter and it goes back to late 70's.
