Brass sticking in chamber

[DLT]

My uncles rifle (model 12 with a shilen select match barrel ) in 6.5 creedmoor sticks brass after a couple firings on new brass both lapua and alpha. He doesn’t have clickers just hard to extract when the bolt is all the way up. He does anneal but that shouldnt matter only after a couple firings. He is bumping brass back a couple thousandths. The load is near max by hodgdons data. The brass that sticks in his rifle does not stick in a factory savage he also owns. Is it the dies ? Thanks for any advice

Dirty chamber?

IMO there ^^^ is your answer.
Different chambers, different rifles so all bets are off.

The brass that sticks in his rifle does not stick in a factory savage he also owns.

But the load could be too hot for that particular rifle even though Hodgdon says it's NEAR max load. Tame the load down a bit and see if it helps in my opinion.

Rough chamber. Any radial grooves on the brass?

Would that cause it even on second firing ??

Going to clean it tonight and make sure. Not many rounds down it

Not a rough chamber. Brass looks fine. I have seen some that looks sand blasted so I know what to look for

I didn’t know if his chamber was tighter and the dies wasn’t squeezing it enough but was sizing plenty for the factory rifle. Same die used for both

It could.

 

[jds holler]

Time to get out the ol sharpie and see where it's tight. jd

If the die was not sizing the brass adequately it seems you would notice it with placing the round in the chamber ?

On a fired piece ? Just insert and close bolt right see where contact is being made

Or fire another one after marking it up.

 

[jds holler]

I think I'd try both before and after. AND just for kicks, I'd keep track of the head stamp and insert the same way. You may find out a little more-- or not. jd

His load is 41.8gr of H4350 with a 147 eldm

Be nice to see a picture of the brass but if you say it looks fine ….

 

[Bill Norris]

Not real sure how close to max I was but I was loading 42.0 gr. of H-4350 under the Berger 144 gr. for a friend of mine recently and it seemed fine but there again we are talking about two different barrels. We stopped there because accuracy was jam up.

If the bolt is not hard to lift, but is hard to pull back and extract, you should be able to see some radial mark on the body of the brass, or possibly a swipe on the case head.

On the body of the case if the bolt is able to twist the fired case in the chamber. On the case head if the bolt rotates but not the brass. Slight out of round in the chamber can do one or both of those.

What happens trying to rechamber a sticky piece of brass?

First thought when reading “match chamber” always comes through as tighter than factory. Therefore higher pressure than normal with published data.

As someone who loads rimfire cartridges, the first and sometimes only indicator of pressure is hard extraction.

But as also shooting a lot of antiques, an out of round chamber or one with a defect, will do the same thing.
