How important is neck Tension on pistol ammo? I know is extremely important for rifle ammo and accuracy.

Reason I ask, was loading some 44 magnum for my DE, and noticed the Privi Partisan(PPU) brass keeps next no neck Tension at all when seating, even sized multiple times just to make sure. All other brass was fine. Reading up on it it sounds like it's a problem with PPU brass as the case wall is actually a little bit thinner than most.

Either way I loaded the ones that were coming through in the pile. The crimp is enough to hold the bullet snuggly, but If I use all my thumb pressure or or push the bullet nose down on the bench I can get them further into the case.

I won't be using these in my autoloading pistol obviously, but wondered if they would be safe in a revolver. Or if I should just go ahead and pull any in the Privi brass.

Just curious of any safety concerns there might be with minimal neck Tension.

Loads are stout at 24gr of h110 behind a 240gr Campro.

Any advice is appreciated
 
You can't set them in place with a roll crimp or FCD? If it goes in that easy it will likely walk out as you shoot, possibly leading to a locked up cylinder.
 
I’ve been having the same problem with Remington brass
Going to try and anneal them and see if it fixes the issue, if not they will get tossed

There is enough tension the bullet wouldn't drop passed where I was seating before I crimped, it is a decent crimp, not sure if they would walk out or not. But recoil and what it can do will surprise a person sometimes. Just did my count, 224 mixed good brass rounds and 32, PPU. Wouldn't be too hard to pull them, but would definitely be easier to shoot. I could load them as single into the revolver as well

I did notice the RP brass didn't have as much Tension as the federal or Winchester as well. But it wasn't loose enough that I was concerned about it.

Pretty hard to get in trouble feeding them one by one. If that preferred over pulling them I think you have found a good solution.

I'll do that then, just wanted to make sure it wouldn't be an issue, Ive read h110 can be problematic with pressures, mainly if it's not a full case.
 
My experience is that it varies with:
brass thickness,
sizing dies which are all over the place, and sometimes won't deal with thin cases, which I prefer to wasp sizing,
then your expander comes to play,
and actual bullet diameter.

I solved my issues by mostly shooting unsized cast bullets (cast are not to be used in DE's).

As you pointed out, autoloaders will often set bullets back in cases, even with factory ammo.
 
If you're able to push the bullet further into the case with just finger pressure, they will definitely start "walking out" in your revolver - maybe even more so than a pistol, as the slide of a pistol will absorb a bit of the recoil energy. I had loaded up a bunch of .44 Mag for my Super Blackhawk, using a 240 gn bullet and a moderately healthy dose of W296 - but not max. Crimped them too - but apparently, not enough. I couldn't get through 6 chambered rounds, - maybe two or three - before the bullets started walking out and preventing the cylinder from rotating. Back to the bench and dialed in a more substantial crimp (tapered, not rolled) and the problem was solved.
