I see a faint line that goes around the case below the shoulder after full-length sizing, is that a problem? Two: I bought some Winchester brass and after full-length sizing, the case oal was .09 shorter than the max trim lgth, ever run into that? Also, I had a case that the flash hole had brass there, it hadn't been cut out. Probably not going to use Winchester brass anymore

.009 under the Max is okay. In fact, most manuals reccomend to trim to .010 under max. The case will grow with each loading. When it reaches max, trim.

Nothing wrong with brass being .009 too short, just means that you have more firings before you have to trim.

The only problem you may run into, is when crimping. I'm not sure if you are using a bolt or an auto, but I never crimp any bolt gun ammo, it just causes problems that are not needed. I only have one auto and I do not crimp for it either.

The non punched flash hole is probably caused by the rush to provide components for the wild demand on ammo. Lack of quality control, I'm sure it is happening to all makers as they push their machines to meet the demand.

The faint line is likely caused by the lack of finish on the die interior, do you see it on other brands when sizing them or just Winchester?

Okay, thanks for the input, I usually use Remington brass and never have those variances so I was concerned. The brass is being use in a TC Encore so I'm not crimping.
