Quirks to Gas Checked Bullets?

[Oic0]

I had a set amount I was belling the case mouths for my straight lead bullets. When I started trying to load gas checked bullet (which I am new to) they shaved lead like crazy. I think one even went in a bit crooked. I can't tell but im not firing it. After one or two I went back and progresively opened em up more and more until they went in clean but in took a lot. I swear they look a lil bulged.

Is this all alright? Good and safe to shoot? Yes they do all chamber.

There are no more 'quirks' to GC bullets than any others.

Too small cases will get bulged by the bullets, matters not what kind. What you see is the effect of a case that has been sized down to a much smaller internal diameter than the bullet.

Bullet side wall shaving is due to insufficent chamfering of the case mouths AND/OR insufficent mouth belling. The same things increase the likelyhood of a canted bullet.

Neither the bulging cases or the shaved bullets have any safety impact.

Gas checked projectiles have to are supposed to have an area to receive the gas check?? Do yours?

Most of my .40 reloads look about like that with a .401 lead bullet. Exact same thing with 9x18 makarov rounds with .365 lead bullets.

Haven't had any functional, safety, or brass re-usability issues with any of them.

Ok, I just wanted to check before I shot em. Didn't know if having the bullet held so tight would increase pressure.
I assume the canted bullet isn't safe and ill need a kinetic puller to reclaim the over priced brass later?

Are these home cast? Double check for roundness and size. The shaving comes from insufficient belling. If they're round, even a bullet that goes in a little offset, should right itself upon being seated to the correct OAL. When I seat one goofy, the case mouth will bite into the bullet and you can't seat normally. As long as your load is within safe parameters, and your seating depth os good, shoot'em up.

Well, we still don't know what cartridge we're talking about, or who made those bullets.

But, that ghost image of the base of the bullet is entirely normal. As for the one that is crooked, it too will shoot without a problem. It may be a flyer on target, but safe to shoot non the less.

New Winchester .500 S&W brass with a Matts Bullets 460 grain .501 LFN-GC (Ranger Rick Bullet).

Unrelated but working up a load starting at 33 grains of W296 up to 36 grains in half grain increments. Magnum primers.

That's normal looking.
Your resizing die is sizing the brass smaller than the width of the bullet & gas check.

My 38Specials look like that too.
It's no big deal.

I know little about cast bullets, but I have heard an interesting anecdote from Randy Ketchum of Lynnwood Guns. He had fliers on his target and traced it back to the gas check coming off the bullet in flight.

Gas checks coming off in flight are caused by insufficient sizing when applying the GC in the lube die. I've fired .357 Mag bullets @ 1895 fps (in a rifle) and recovered the bullets afterward with the gas check still intact.
