Guys--A friend is contemplating the purchase of a Lever gun in one of the following calibers, .357, .44 Mag, or the .45 Colt. He asked me of the 3 cartridges was there any accuracy advantge of one over the other in the Lever platform. The gun is going to be used primarily for local metallic silhouette shooting and occasional deer hunting. The metallic silhouette is only to 100 yds on the NRA pistol targets and any of the calibers is capable of knocking over the rams ( I shoot .38 /158 rn/1100 fps in my single shot with good results). He is looking hard at the Marlin lever guns but again accuracy is his prime concern with cast bullets. Your thoughts?? Thanks Nick
