Actually, a lot of Bullseye shooters really liked the Star 185 grain swaged Lead HPSWC. Star just went out of business, so they have been scrambling to find a replacement. Other Bullseye shooters sware by bullets made from straight linotype. I never had any luck with swaged bullets for 45ACP compared to Commercial Hard Cast and Cast-My-Own SWCs, but that's me.
I think shooters find something that works really well for them, then they start developing theorys why its better than anything else. The result is a proliferation of "Old Wives Tales" recipes for the best loads. The truth is, there are many solutions to the problem and if you find one that works for you, use it.
