why wouldn't this work?

instead of full length resizing or partial (shoulder bump) just put the brass without a bullet in it into your chamber then close the bolt. In other words use your rifles chamber and bolt to bump the shoulder back if needed. Do this on every reload so if the shoulder needs to be bumped back it will only be a small distance.

Wont work!After firing the should has been pushed forward to match the chamber.The best one can do given the ops idea is to necksize.

[Gringo Bandito]

Try it. My bet it that the neck will not be sized correctly enough to firmly seat the bullet.

Well leme see??


Isn't that were the spent shell came from? What's putting it back in and closing the bolt again gonna do that didn't already happen after u fired it...???

If the shoulder is already at the proper spot, it will work fine. After a few full power loads, the bolt will be harder and harder to close on the case and you may get a stuck bolt where you'll need a mallot to open it back up.

For fireformed cases that were shot in that gun before, all you need to do is neck size the cases and you are good to go for around 3 more reloads before you need to bump the shoulder back with a "partial full length resizing". With powder puff loads (10g Unique). You can go many more reloads just neck sizing.

Your chamber is cut larger than the case's dimensions so it won't work. Just get a neck sizing die and use that so you can extend the life of your brass.

I'll try it for a while and see how it works, will report back.

the idea is to bump the shoulder not neck size, use the chamber itself instead of a die to bump the shoulder. I am not talking about neck sizing.

And they are saying that the brass expanded to fit the chamber. So how is putting the brass back into the chamber going to bump the shoulder back? For it to bump it back the chamber would have to be smaller, it's not.

You don't need to bump the shoulder if the bolt closes. You will have to neck size to be able to seat the bullet though, or it may just fall in.

The cam system on the bolt of your gun has nowhere near the mechanical advantage of even a Lee hand press much less a bench mounted press. Plus the bolt is not designed to squish a big case into a chamber Since the brass (hopefully) still has some springback, if you put a case that is too big for the headspace of your chamber, it will be incredibly hard to close and then open the bolt, plus the springback of the brass will still make it really tough to close the bolt again the next time you try to chamber that same case. Believe me, I've tried it and you cannot effectively bump the shoulder back of an oversized case with the bolt of a gun.

So the easiest solution to the question is to go ahead and try it out. You migh have issues with the neck not holding the bullets, but they only way to find out is to try it.

I think I would prefer to use my big old press to size than my sweet old 700 Remington .

Are we talking about a production rifle from RemChesVage or a custom rifle with a minimum dimension chamber? My Interarms MK-X in 270 Winnie has a tight neck and the brass I shoot out of it will seat 270 bullets without neck sizing. Probably why it shoots in the .3s with 110 grain varmint bullets if I don't heat up the light weight barrel.

Resizing the brass is so that it'll take on a proper shape to hold a bullet and chamber (from shoulder bump) properly. You're resizing the brass that came out of that chamber, how would the chamber be able to resize any part of the brass to make it smaller?

And if you're only shoulder bumping, you're going to neck size it in a different step? why bother with 2 steps when you can do 1?! what's the thinking here?

Brass springs back a little either by firing or sizing. It's already slightly smaller than the chamber it came out of. otherwise you won't be able to extract it or chamber it. When you size in a die, you're actually squeezing it shorter (shoulder bumping) than the die cavity and the spring back shape is shorter than the rifle chamber which is what you'd want. Even if you're using a different rifle with chamber shorter than the one you're sizing, the body diameter may or may not fit the other gun.

No need to report back, it will never work thru the same gun.
