In the past I have cast a lot of gas check bullets for my revolvers. They shoot pretty good and I have had no problems. I am in the process of deciding on molds for my .45's. I can't decide on plain base vs. bevel base. It seems like somewhwere I have read that as a rule plain base causes less leading (?gas cutting) than bevel base bullets. Makes sense to me because of a better seal. Also, I have read that plain base bullets give better accuracy than bevel base- better seal = better accuracy/less fouling. What are yall's experiences?

The plain base have always given me less leading though not always the best groups. The pistols I cast for now like the plain base. Bevel base sure drop from a mould easier than the plain base do. I vote plain base.

bevel bases make the bullets easier to start in the brass and really help with lead shaving. can't say they are more prone to lead than a flat base but they don't shoot as well in my guns as a plain base. i've never heard any of my friends, that cast, say they prefer bevel bases.

I vote for plain base. I've never gotten the accuracy from the bevel base designs that I can from the plain base ones. Even tried using a BB mould and cut the bevel out of it. Groups tightened up and leading was reduced. For the home caster I'd go with PB every time.

I've been shooting cast bullets for over 35 years. Agree with Nobade 100+%. Have run tests of Plain base vs bevel base numerous times with handguns and rifles. The plain base always come out ahead.

I like bevel base for my 45's shooting a low velocity load for IPSC. They're easier to load...and I load a lot of 'em, but for accuracy plain base can't be beat

As per this post, I did basically the same thing. I already had the RCBS 2-cavity mold but I recently bought a 4 cavity Saeco 69 which is a flat base number 68. I have cast several hundred but haven't lubed or shot them yet- waiting on the new old Star sizer from California. Got a feeling it is gonna be the best money ever spent.
