So I just got a box of 30 cal berger 215 hybrids and started messing with them. I put one in a fired case to see where they would hit the lands. In any case I couldn't get the bullet in the case. I had to use my seating die to get it in. It fits like the case was neck sized which it was not. The last bullet that case fired was a 180gr accubond.
I'm a little concerned that the bullets are going to fit tighter in the barrel and up the pressures. Anyone got any experience with this sort of problem?
 
Maybe mislabeled by Berger. Happens...
Try a set of calipers and see what is says.
Try a few pieces of brass as well. Could it have been a piece that you already prepped? I always have to slightly neck size to get a piece to chck for lands.
 
Checked and the bergers all measure just a hair over .308 and the accubonds all measure a hair under .308. Maybe that was the difference. I know I didn't prep the case because it's still got the dented primer in it and usually a bullet will just sort of slip into the shell.

Maybe it's nothing maybe I'm being to cautious.
 
Brass is a naturally springy metal, it expands and contracts. And after firing a round, it will contract back again close to the original neck diameter that it was formed to. Once brass loses its elasticity you can anneal them to help remove any work-hardening caused by pressures from constant re-sizing and shooting. But, brass will eventually wear out, and if they're too far gone, you just chunk them in the trash and get some more.
 
One rifle I had the neck of the chamber cut so I never sized the brass; except to push the shoulder back when closing the bolt was not easy. The bullets fit like the 215s you're talking about. Of course this required turned necks.
 
Work your load up as normal watching for pressure.
I would anneal often and as precise as possible to keep neck tension consistent.
 
What happens when you try to place a 180 accubond in the fired case neck? Is it also a tight fit?

IMHO If you cannot get any 308" bullet into the case mouth with little effort I would suggest that the chamber neck dimension is too tight for your unturned brass. I would want to know the exact dimension of the chamber neck if for nothing else just peace of mind.
 
Yes i have experienced it. Fired cases dont necessarily provide a clearance fit with a new bullet. Buy the hornady overall length case and use the hornady tool to determine your distance to the lands.
 
I would be more concerned that you CAN push a bullet into a fired case. I can't with my .260 (142 smk's, 143 eld-x), 300 wm (180 ab) or 25-06(115 berger, 110 ab).

I used to be able to do it with 50g vmax's in my .220 swift and once fired Hornady headstanped custom competition brass. I tossed them. None of the frontier headstamped brass allowed this to happen.

I have had this conversation hundreds of times. We are all aware of the pressure signs. But the average reloader isn't measuring case head expansion and doesn't have a pressure trace.
So most of us work up watching for pressure.
The fact lots do it doesn't make it a good idea, nor does it change what I stated.

The "signs" are saying there's way too much pressure.
 
Thanks for all the input. Looks like it'll probably be ok. To be honest I'm looking at a rebarrel job on this rifle pretty soon. And i got some brand new nosler brass so I'm feeling ok about it after measuring a bunch on the bergers to make sure they really are .308. The brass I used had been fired 5 times and was Winchester brass.
