Bean Man, Fred, I am going to find out the answer to your question very soon. Yesterday, I purchased a new CVA Accura V2 M.L. rifle in .50 caliber. open sights with the new nitrite finish/coating and a regular camo stock/forearm. I plan on using Black Horn powder; the Federal 209 hot primer; and the Federal sort of new copper bullets. the Federal bullets come in 350 grain and all I have here at present is 270 grain and I will do some target practicing with the lighter weight Federals then switch to the 350's. I like the feel to the Accura. Will read the instructions about adjusting the trigger pull after I do a little practicing with the weapon. Will keep you informed as to my progress.
