Brass not fitting a gun of the same caliber
« on: September 02, 2016, 11:45:51 AM »
My uncle does all of the reloading for our family.  To make his life easier my brother and I switched from shooting 30.06 to .300 win mag, now my uncle, dad, brother and I all shoot the same caliber gun.  When trying out some of the previous reloads that he did, they didn't fit in my brothers gun.  (dad and uncle have a ruger, brother has a sendero).  Then we tried some empty brass that we already fired, that didn't fit either.  The factory ammo we had fit just fine in my brothers gun, but any brass that was shot from my uncle or dads gun wouldn't fit in my brothers.  We took two factory shells and fired one out of my brothers gun, one out of my uncles, the round fired out of my brothers gun fit back in his gun just fine, even after it was resized; however the round my uncle fired wouldn't fit into my brothers gun once it had been fired.  Anyone had this same experience?

Do you know if he's full length resizing? If not, it would make sense that they're not fitting in your brother's gun, it apparently has a tighter chamber.

 :yeah:

If you are going to use ammo in multiple guns, full-length resizing is probably the best bet..

he is resizing full length, it is the belted part at the bottom that does not fit.

Hmm... well in that case I guess your brother will need to keep his brass separate, and only reload his brass for his rifle.   :dunno:

that is what we decided as well.... it apparently has something to do with the bulge magnum calibers get just about the belt.

The belt's not expanding.  You'd blow a gun up first.  You need to get some brass fired from your brothers gun and adjust the dies until they just size the brass and then test with getting some brass from the other guns and seeing if the dies size that to where it will fit your brother's gun.  You may need to keep adjusting the dies to size more until the other brass fits your brothers gun.

Only thing that would be an issue is if your brother's gun is a semi and needed a small base die set to load for that gun.

I would send a link, but i cant since i am at work, but check out larrywillis.com and his belted magnum collet resizing die.  I think this is the die that addresses the problem.  that is where i got the expansion above the belt wording from.

It's always a good idea for brass life to keep the brass separate. Each gun may not like the same load anyways. I always even use different dies for each rifle. Even if same caliber.

have had this issue in a pair of wby 340's I have. on "sticks" brass if fired from the other.. full size pressed or not. only answer I have that works was to separate brass for the separate rifles, start with new for the sticky rifle and never swap out..

Same issue for my dad and I with our 7mm Mags. We just keep our brass separate, no issues.

If a properly full length sized case won't chamber in the gun, then the chamber is out of spec. If you're getting enough expansion above the belt (or at the belt itself) to cause problems then the pressures are most likely too high. If the chamber in the problem rifle is cut slightly off the centerline of the bore or a bit oval shaped it could have this problem as well. I've had 2 factory guns with mis aligned chambers and I know of many others that have been that way.
