brass getting stuck in chamber...

[dcnyli]

So this has happened twice recently where the extractor rips off a pc of the rim and the brass needs to be tapped out of the chamber. This is 4-5X fired federal .308win brass, and it's been FL sized(bumped back .004 +.-).. The chamber is clean, and the rounds fire dead nuts where they are supposed to. The bolt closes with some resistance but when opening the r700 bolt, the last part of the lift where it cams is difficult and takes some banging here and there, but now we are getting stuck rounds....

what can I do to fix this? I was going to get a "bump die" from forster prior to this issue to help keep my brass in check without FL sizing, but not sure what to do at this point. I do get some runout with the FL sizing, or inconsistent bumping, everything is very tight but every now and then some brass just doesn't move enough I think in the die and isn't bumping much at all

any help to the newbie reloader?

load is a mild 42.6gr varget, 175gr VLD, WLR primer

The bolt shouldn't be resisting closing. Are the cases trimmed to trim length? Sounds like an issue with brass length or coal or both.

 

[dcnyli]

COAL is well under magazine(it's short throated/tight chamber to begin with), and the brass length is 2.008 & 2.0065 after firing(i trim regularly). Only measurement that looks odd to me(and possibly first time i'm seeing it but could have always existed) is the neck diameter towards the top is .341" whereas it's usually .340"

I've put about 2500-2700 rds thru this rifle

Are you crimping the case mouth?

Could also be a neck thickness issue. With a tight chamber, you may need to neck turn.

No sir

I will mic it, but not sure about having to turn necks... Eek

No sir

Can you chamber and extract a live round (your reload)?

 

[dcnyli]

yes

Winchester brand 308win brass is a cheep investment.
New brass full length resized and trimmed.

Load it,shoot and repeat

 

[918v]

yes

I'm suspecting your sizing die isn't sizing. Maybe you should compare your fireformed case dimensions to your sized case dimensions. You might need a small base die.

Look at Sheridan Engineering minimum SAAMI spec gauges: http://www.sheridanengineering.com/images/SG308WIN_2.jpg

I bought the 308 first. Then a few weeks later I bought the 223. If they made a 300 WinMag and 25-06 I would get those too.
