Well Grouse I don't know how many shots you plan on taking while hunting. My Accura V2 has the CVA Blackhorn BP and I haven't had any issues with it. You may have read my latest thread on my hog/deer hunt. My rifle performed flawlessly taking 3 heads of game with 3 shots (one shot each).
Yeah there is some blowback from the primers but who gives a rat's butt? Ignition is reliable and the rifle is accurate. Who could ask for more?
