Brass sticking in chamber

[DLT]

I

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

I can get some next chance in there which won’t be long. The times I have looked it over nothing stuck out to me that could cause it.

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.

I don’t know if it’s a “ match chamber “ it was ordered as saami spec but it was shilens better barrel offering I think they classify their barrels as match and select match

Mic the case head. I had some alpha brass stick at max pressure due to case head expansion and tight chamber. Backed the load down and all was fine. Maybe I got a batch of softer than normal brass but a lighter load stopped the sticking

chamber cut for a certain neck size?

Sounds like a mis-timed bolt handle to me.
Like he is running out of extraction cam

No sir should be saami spec

Since it’s a savage we can shim the baffle to fix that potential problem correct ?

First thing I would check is the length of the brass in that rifle compared to the chambers in both rifles.
Could be a shorter chamber in the one, so the brass is sticking for that reason.
If that check out okay, then that load is just too hot for that rifle, back it off at least 2-4 grain and see if stops the issue.

OP didn't mention if he is full lentgh sizing. But I would suspect the sizing of the base of the case is the issue.

May be the case is enlarged in the web area.? It happened to me on cases that measured .4705" and above on the web

 

[Firearmsunlimited]

Heavy throat carbon build up.

He is off work today due to the rain, uses a standard full length hornady sizing die. His case head measures the same as new ones. Where it’s scuffed up it measures .004 bigger than a new piece

 

[RustyInBend]

How do the primers look? Any primer cratering?

He uses a hornady brand full length sizer every firing and anneals

A larger measurement there may or may not be a big deal.

Need to measure on both sides of the mark.
Check If it measures smaller on the case below the mark, like there’s a step in the chamber, or both sides like a bulge.

If you have a straight edge against the body, you might be able to see it.

He says it’s tapered can’t feel a bulge. I’ll get him to straight edge it

I’ve seen it both ways. Or maybe all three.

A dual taper in the chamber

A ring in the chamber that appears as a bulge in the brass.

A bulge in the chamber that appears ring in the brass.

Most important thing is, do not cast the chamber without a good idea of what it is. The brass will collapse if you have to drive the case out, a casting he may have to beat the thing to death to get it out of there is a ring in the chamber.

Going to scope it next

Looks to me like there was a ring in the chamber that was polished out leaving a bulge. Give it back to who chambered it and request they fix it.

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

You never thought to back off on the load. Common sense.

The Hogden website give a max load of 41.8 gr. of H4350 at 60,000 PSI
The Berger website has 40.7 H4350 with a 140 gr bullet.
From your post it sounds like you always push the limits.
It's so easy to back off the load and see if the problem goes away. You are looking for all kinds of measurement issues which will drive you nuts. You know you have hot loads and you refuse to deal with it.
