What are some of the reasons shells stick in the reciever even with minimum loaded shells?

[jim147]

Things that come to mind would be:

1. A pitted or scored chamber.

2. An extractor problem.

3. A weak case.

4. ect. ect.

Without knowing the firearm or what the case looks like it is all just a guess.

Dirty chambers, gas blowback. Are the shells coming out dirty or just sticky?

When I let it cool down I can extract the fired case. this is a rem 721 300 H&H.Extractor is fine.I can tear the case head off if I force it.A no-go guage will not close so head space should be ok.chamber looks shinny but without a bore scope I can't see it all.Thanks

The problem I read is that you can pull the case head off. That tells me you are oversizing your cases.

The 300 H&H has a very shallow shoulder and it is easy to push it too far back.

Die manufacturers supply an instruction sheet that typically tells reloaders to "size to the shell holder plus a quarter turn" . This advice is totally bogus, especially with respect to belted magnums. You will find that shoulder distance is not controlled, therefore a sizing die will do different things to cases fired in different rifles, even though the belted magnum caliber is the same.

Another reason I dislike belted magnums.

First things first. Fix the things we know are wrong and then see if that fixes the problem.

Follow these links and get your self a 300 H&H case gauge. If you notice, these are adjustable. That is because the shoulder distance is not standardized. You have to set it up using a case fired in your rifle.

You say the chamber is clean and free of pitting.

Powder overcharge is what I would look at. Was the bolt hard to open?

Sizing cases too large would make them hard to insert, not hard to extract.

I have never loaded the rifle hot,I load slightly over 30/06 velocitys.I clean the rifle everytime I use it.The bore and chamber is spotless.

I forgot to add that my reloads shoot very well in a friends 300 H&H.

If I had cut the chamber I would be able to tell how much head space your rifle has in thousands, a chamber cut by someone else? No problem, purchase new cases or purchase a few once fired cases from the range, cut them off in front of the belt, because it does not matter make it one inch, if you reload size the cut-off cases then try to chamber, if the test cases chamber without resistance to bolt closing check the chamber length from the face of the bolt to the shoulder of the chamber, again new or once fired cases will work, I cut the belt off of the case, neck the case up to 338 or 308 (I use a 308 Norma Mag or 338 Winchester Mag sizer die) then start necking the cases down with the 7 Remington Mag die, BUT, with a feeler gage, adjust the die off of the shell holder with the ram up, I start with a gap of .012 thousands, after moving the shoulder back attempt to chamber, if the test cases will not chamber, decrease the gap to .008 and attempt to chambering the cases again, if you do not get consistant chambering before you get to .000 gap, the chamber is short, I will not say 'not a problem' I would adjust the die down to the shell holder with an additional 1/4 turn (what ever that is), secure the die and continue sizing but with a feeler gage between the deck of the shell holder and bottom of the case, this sizes the case for short chambers, I short chambers first, then road test, if after road testing I like the results, I finish the chamber.

In the perfect world the belted case can not be shimmed up more than .004 to .005 thousands, that is the reason I cut the belt off when checking for short chamber.
