Thank you I obviously didnt read my hurried reply. I was trying to say that the HBWC normally have the sharper edges and are cast. SWC should have never made the post.Originally Posted by willie
By definition, the shoulder is part of the swc design. Swc's are not hollow. Some wadcutter bullets are. The purpose of being hollow is that the base will expand upon firing and form a better gas seal and at the sake time conform to the bore more completely. Supposedly, they are claimed to be more accurate. A downside to hbwc's is that past a certain velocity level, a piece of a base may break off and remain in the barrel.
Richiecotite, my observation has been that cast wadcutters have sharp shoulders. This fact is a function of mold shape. Swaged bullets will have less sharp shoulders because they are pressed into a die under tons of pressure. Whether or not they are hbwc's or dewc's is not relevant. It depends on the particular die shape used in the forming process.
Cast bullets can be made extremely hard depending on alloy. If dropped from the mold into water, then they become even harder. If cast and then heat treated and then dropped into water, they become harder than a preacher's dick, which is much harder than Chinese arithmetic. So, it's now clear that a cast wc made under selected circumstances can penetrate with zero deformation.
Some may not know that wc's were popular with bullseye shooters primarily because they created a perfectly round(easily scored)bullet hole. Another reason is that with charges like 2.7 grains of Bullseye powder, the 148 grain wadcutter was cheap to reload and also was accurate out to 50 yards. Recoil with this load is low. My opinion is that other bullet shapes can be loaded to be just as accurate or even more accurate than wc's. One reason is that one can experiment with a greater powder range. Because the wc takes up so much case capacity, using slower powders is not an option. Past 50 yards the wc fails.
