Place the offending cases upright on a flat surface and see if they are all straight.
If there is play in the bolt head when the bolt is closed, the case can swell to one side and then the case head sits at an angle to the body. If the case does not go into the chamber at the same orientation it came out, there is a good chance that you will have trouble closing the bolt.

This is very good and new to me advice, kinda thing Oom Drie usually schools me.


Perhaps turning the case in increments through 360Deg and trying to chamber each time might provides clues ?

I want to be able to have a drink at your wedding or if you offer at a braai, but do not want to be a drinker again.
I have had like 5 beers in 3 months and I am happy with that, even triple that would be acceptable. I usually drink alcohol free now and find it very self pleasing to be able to, but decide not to.

Do not see a collet die video ?

************************************
You have informed us that you have stopped drinking. I must now ask what you have been smoking? There are several videos and the collet settings are just before the handguns.

Unset all your 303 dies.

Use those 14, remove the decapping rod from the sizing die, and set the die to size the brass to the rifle chamber. NOT how the die manufacturer says. It's an iterative process, size, chamber check, size , chamber check, until the bolt has resistance in the last inch of close.

Yes, the 303 headspaces on the rim, and yes, this method gets it to headspace on the shoulder as well.

My suggestion is to get into the habit of full length sizing every time.

Then use the collet neck sizer to open up the neck.

Reset and re-configure all the other dies' settings, including crimp if you use it. An incorrect seating die setting that crimps and seats at the same time can also buckle shoulders.

Get into the habit of labelling things. If you put 20 pieces of brass on the table, put a note with where it came from, what was the last thing done, what's the next thing to do. Otherwise you put some brass from a friend's rifle on the table, and then later mix them with a few from yours because you forgot where the ones on the table came from so you assumed it was from yours.
