Flattened primers on .32 S&W Long. What'd I do wrong?

Yes, but it doesn't make sense that the .32 H&R Mag loads with the same everything (powder, charge, primer, bullet) are not flattening and producing less felt recoil. Given the increased powder/air gap due to the longer case the pressure should be even less.

Is it possible I was blowing the skirt off the bullets in .32 SWL and I didn't know it? I don't believe they were hot, Idk what the signs are of a blown skirt.

Have you checked the rim thickness of the brass?

In my experience the .32 Long gives very little leeway. A tenth of a grain can be the difference between good looking primers and flattened ones. High-level competitors will discuss hundredths of a grain when testing and comparing loads.

I have no experience with Titegroup in the .32 and don't want any. For my money, Bullseye is the go-to powder for the cartridge, though I have no doubt AA #2 is also a great choice. 231 also sees a share of use in competition guns. VV rules the roost in Europe and if you can get any where you live it is worth the effort.

It's important to note that many modern guns - especially the Euro target autos - thrive on higher pressures. Competitors often are willing to overlook pressure signs that more casual users are not, so some of the published data can be a bit warm.

In the OP's shoes I would load the Speer WC flush with 1.5 Bullseye. If that load isn't safe and accurate then there is something wrong with the gun.
