Messed up sizing on 500 rounds

[evan the cdn]

Bullet not seated straight, or heavy crimp buckling case. My guess.

They all seem straight. Are there any signs to look for that would indicate the crimp is to tight?

It's mostly once fired Winchester brass and Aim 147gr bullets if that matters. OAL is 1.15".

Thanks Kim. I'll give that a shot.

Would a Lee Factory Crimp die size the loaded case for you? I think it might.

I have used a Lee Factory Crimp die for exactly the same situation. Ran 1000 through, problem solved.

It was commercially reloaded 9mm that was on the large size, and one gun that had a tight chamber.

Hello Evan.
In my CZ Shadow, I have to seat to 1.080 to get the 147"s to chamber, The throat is short on the CZ's and you have to seat the bullet shorter to make them fit.

They do look a bit long in the picture and this would be an excellent next step to explore.

The nose profile is different from one manufacturer to the next. This applies to bullet moulds as well.

Cartridge length should be measured from the orgive or tangent. The overall length may be determined by magazine depth.

That won't work the bullet is larger in diameter than the case body and won't pass through the die. A Lee Factory Crimp Die is the answer, and an inexpensive answer at that.

It's worked for me in the past with rifle.
Beat's the hell out of having to pull down 500 rds.

Yep.

Notice how the bullet bulges the case above the base of the bullet in the picture?

The case was previously sized to the smaller diameter by the sizing die. You might be able to get it to work by backing off the sizer, but it might not size the base enough.

The "coke-bottle" look of those cartridges is common and has nothing to do with chambering. If the case fits to the base before the bullet is seated, it should fit after. If the bullet is the proper diameter, the only other variable is seating depth.

Joe, I believe SandRoad was referring to the problem of attempting to run a loaded round through a sizing die with the decapping rod removed, rather than chambering it in a firearm.

No expert here, but I've loaded upwards of 500 rds of 9 X 23 Steyr through 9 X 19 dies with running them through a .357 magnum sizing die ( with the decapping rod removed)as a final step to make them work in the pistol.
It's a PITA but do-able.

Ahhh, gotcha.

Yes, thanks

The bulge at the top will stop the sizing die going lower (tapered case) before the base of the sizing die can fully size the base. If you force the die all the way down, the bullet inside the case will also be swayed.
