reshaping gaschecks

Several years ago I came into a bunch of gas checks, from an estate sale, part of which is about 5000 .32/8mm checks. I'm sizing a run of the NOE 314-115, half PB and half GC. The only .32 cal. bullets I'm casting or loading, all use a .30 cal. check, which I'm making from aluminum. When sizing the PB bullets I got to thinking about those .32/8mm gas checks. I just recently bought the GC flaring tool Brad came up with from NOE. So decided to see if they would fit on the bullets I just cast. Of course they were too big, but after running them through the GC flaring tool, they fit as well as any check I've ever used, in fact probably better. Of the 5000, about 4000 are the Hornady crimp on, and 1000 of the old Ideal checks. The Ideals form well but come off real easy after being run through a .313 sizer. The Hornady crimp on fit beautifully, and can't be pried off. The flaring tool appears to square the bottom and displace the "crimp on rim " to the outside, when flared, and is just visible upon close examination. When the Hornady's are seated there is a consistent and fine gap left just about to the bottom band. I shot a few today and they appear to shoot nice tight groups. Can anybody think of a reason not to use these?

They fit, they stay on, they shoot well . . . What's not to like. The Lyman's I've never been too fond of and haven't used them in probably 30 years.

That is the purpose of Brad's check sizer after all. To make them fit correctly.
