Stuck case in TC Venture

Was your ammo laying in the sun?

I'm guessing the Venture doesn't have a whole lot of primary extraction power, and your reloads may have been a little hot, or you've got a rusty/dirty chamber.
you check your chamber for in issues first, to remove that possibly.

then pull the components on a few of the ones from the new batch, andake sure everything checks out. Also did you open any new powder or bullets for this lot?

A few things we don’t know;

Are you well versed in loading?
To what length did you trim?
Did you clean the rifle before its initial range outing (remove preservative)?
How often do you clean?
Have you measured the brass that stuck?

If those that didn’t stick still don’t stick, and those that did still do, I’d say the ammo was the problem. A Wilson Case Gage is a great way to check case dimensions quickly.

hrrmmmm, maybe check your oal measurements again. I've never seen it, but I've been told that it's possible to get a different ogive taper between lots, and if your near the land it mighta stuck.

brass its self might be an issue. Is it old? like 4-5shots? more often than not you'll lose the primer pocket, or crack a neck, before they will stop popping back off the chamber walls, but I've had cases stick with no other explanation.

I’m no expert but have been loading rifle rounds for over a decade. I’m pretty anal about the process.

I trimmed to 2.025”

I did clean the rifle when new and clean after every twenty rounds.

The problem brass measured 2.025” and 2.031”.

how bout just infront of case head, as compared to your good brass, or new brass.

PPUs pretty decent brass in my experience. Hopefully one of the loading gurus will come along and have a better idea.

If you still have loaded rounds, check neck diameter vs the fired cases that stuck and report back. If the necks are too thick they may not be expanding properly which might explain easy bolt lift but difficulty extracting. If you aren’t neck turning your brass you probably don’t have the correct tools to measure neck wall thickness but if the fired cases are a few thousandths in diameter larger than one with a seated bullet you’re probably ok. Figure .003” would be good.

Yeah myself and a friend of mine both have had issues with PPU brass getting stuck in the chamber after firing. It was in all likelihood just a bad batch of brass, because we used PPU before and I've used PPU since and no issues. We just scrapped it and we assumed it was case head or case web expansion.

PPU has had some brass issues I had some 30-30 that would stick in a marlin 336 but was ok in a winchester 94 and did same when reloaded.

If it works OK with factory loaded ammo, its a problem with your reloads. Also, when cleaning, don't neglect to thoroughly clean the chamber area.

I believe the brass absolutely is the issue but that doesn’t make it bad brass. Neck wall thickness is vastly different from brand to brand; one reason any load recipe will include the brand used. The problem is two fold: first, if it’s thick, you’re running it into your die after expansion to seat a bullet and some people crimp which forces the outside diameter to be the same for all brass. You’ve just crushed your bullet.

So you don’t crimp for fear of losing accuracy? Ok. You run the round into your rifle’s chamber and fire it. There’s not enough room for the neck to expand properly and you’ve got excess tension on the bullet, increased pressure, and finally a stuck case that couldn’t spring back. If you trim after each firing but don’t chamfer...even worse.

I wouldn’t toss brass at this point. Instead I’d figure out a supply list to start turning necks and measuring. In the end you’ll be rewarded with more complete information on your brass and better accuracy potential. If you go the other way, you’ll be buying a lot more brass and getting fewer loadings with it.

None of this goes without saying double check that chamber for build up. I’ve gotten a number of recent notices from Amazon on micro cameras that can bore scope starting at $40 or so and using your Smartphone as a monitor.
