Every rifle is different, but several do not respond well to pure lead conicals in the fast twist barrels of inlines. Sometimes acceptable accuracy can be had by putting a felt wad between the powder and lead conical. I just chose to shoot a heavy for caliber sabot load (300 grain .430 or .452 pistol bullets) in my inline. I used to cast 350 grain T/C Maxi Hunters for my Renegade, but couldn't get them to group no matter what I tried in my inline.
