In the .45 ACP I use the 200 gr. H&G 68 style bevel base semi wadcutter. Probably the most accurate bullet I have ever seen in .45. Others I tend to stick to gas checks so I guess that would eliminate the question.
I THINK it depends entirely upon the bullet being shot, the gun it is being shot in, and the load pushing it out the barrel. BOTH designs can work and there are plenty of the others that are flunkies. ACTUALLY, I am amazed at how well those commercial MAGMA bevel base bullets shoot, like the 44-240SWCor the 45-255SWC
I normally use bevel based in the 45acp. but in the 38spec, and 45colt I use whatever I have on hand. Just seems in my revolvers the plain based are a little more consistent accuracy wise. Although the bevel based sure are faster and easier to reload.
Seating plain base lead bullets can be a challenge for many reloaders because of the amount of case belling. Too much flaring of the case mouth is bad, but most pistol cases shrink thereby making the amount of bevel ever increasing. The easy way around this problem is to have a bevel base. Bevel base bullets are easier to load and seat, especially the first action of taking the bullet from the pile and setting on top of the case.
Essentially, plain base and bevel base lead bullets shoot the same. The bevel just facilitates reloading...
I know with some of my old Revolvers, I stopped re-sizing the Cartridge Cases, because the Standard re-sizing Dies anticipated the Cartridge Cases to be holding Bullets for a slightly smaller Cylinder Bore and Barrel Bore than my Revolvers actually have...so, not resizing the Cases then aids in fitting the Bullet into the Case, without undue hardship or over-belling and or stretching them out so much with the Bullet. And, the Bullet still fits tight-enough, and, gets a good Crimp...so, I'm happy.
