RE: Looking for some help...
As far as a Maximum load for that rifle..............it might be best to contact CVA by phone or e-mail to find out what the rifle's charge limit is..........................I'm "GUESSING" 120gr - but PLEASE verify that.
Those conicals should work pretty well in that rifle................in fact, I'd expect accuracy to approach being twice as good as your ball load. I've shot the heavier 385gr Great Plains out of my 1:28" in-line Knight and got groups 2" or less out to 75yds - perfect for hunting.
If you use the RS powder, your most accurate load will probably be found somewhere between 85 and 100gr.
