[QUOTE="acloco, post: 226026, member: 6137"] Odd part here, the 32 and 39 BK's tumble in my 12FV. In the 20 caliber bullets from Hornady and Sierra, the physical shape of the two bullet weights are nearly identical (if not identical) within the brands. You will notice a difference in the length of the shank of the bullet that comes into contact with the lands, I call this the "bullet/barrel contact area", which helps determine if the bullets will like the twist rate and groove diameter of the barrel you are shooting. Look in the end of your barrel, is there ANY copper coloring? If so, copper buildup will also cause bullets to tumble. [/QUOTE]
