.303 case headscratcher

[Treeman]

I have sort of done so - I have R24 000 from the weeks I do a would have tally and then put it aside. My bar and associated lunch's, meals account was 4k + a month + home drinks been 9-10 months, so should be more, but I still do the lunch's and going out and alcohol free beer cost just as much as beer. Only thing is I now have two instead of 6.
To be honest I have bought a lot of stuff and written it off to "I would have spent that on booze this month"    
So Ya ! The savings have not gone well.

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.

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