I'm fairly new to the black powder scene. I bought a Remington 700ML about 6 months ago. It was my first black powder rifle. I've hunted for many years with smokless but not yet with black powder. I like the Remington modle I have but its just a 24 inch barrel. I'm using 110 grain of Hodgdon Tripple Seven. I'm shooting 348 grain Powerbelt Aero Tip bullets. I'm pretty sure the twist rate is 1:28. I have talked to people about twist rates and everybody has something to say. I've only shot a 1:28 twist 24 inch barrel. But what people have told me that with that twist rate I should shoot the higher grain bullets. I've shot 348 Gr Powerbelt and 240 Gr TC Sabots. The 348 Gr bullets seem to have a 3 inch MOA. The 240 Gr aren't that tight. I'm just trying to gather any information about black powder. I really like it much better than smokless. I like the controll over your shot you get with plack powder. I was looking at a CVA Optima Pro rifle. It has a 29 inch barrel and is fairly priced. Any of you guys/gals have had any problems with CVA rifles? I look forward to any of your information.
