Excessive flames out of REAR of revolver cylinder-Normal?

It's just time to either anneal your brass or throw it out. The cases have work hardened from multiple firings and they just aren't expanding to fit the cylinder walls as tight any more. The black soot on the case is just like getting "smoked" case necks on well used rifle brass. Fresh brass will expand and seal off the chamber and limit the blow by gas/soot.

I'd be willing to bet that those cases don't size as smoothly as they did on the first pass through a resizing or expanding die. It probably feels like it's grabbing more than it used to. I'd expect to start seeing cracked cases after a couple more loads on that brass.

Thanks for the input. Im going to toss this brass, lower the powder charge, and see what i get from there.

Lowering the powder charge may actually make it worse. Win 296 (or H110) doesn't do well with reduced loads. You're right in the middle of the charge spectrum so I'd probably try going up to either 23.5 or 23.6gr. Win 296 burns cleaner and more efficiently towards the top loads.

Too much crimp? This is a little bit more then I had when the bullets were backing out a tiny bit after about 4 to 5 shots.

Back of cases.

I should have clarified to try this in either new or at least different brass. Otherwise it won't change anything.

Yeah, I'm going to get better brass. Also, these were from factory loads and even on the first loading the primers were very tight going in. I had a couple cases from another brand and the primers went in easy and smooth.

Exactly what I thought when I read 3X loading.
Work hardened brass that doesn't swell/seal the chamber as it should.
