Don't know if I'll get through any better than others, but be sure that your chamber is clean and completely dry...NO LUBRICATION; NO SOLVENT!!!
The bolt lugs need to be lubed; many of use use a good grade of grease.
Also, as others have said, try some different ammo. Could be overpressured Black Hills ammo. Chamber an unfired round and extract/eject it. Look to see if you can see rifling marks on the bullet. Should be easy to see on the moly. If you can see the rifling marks, then the o.a.l. is too long.
Your totally wasting your time and prematurely wearing your barrel's bore by shooting one shot, then cleaning, then shooting, then cleaning, .....
Do a search for "Gale McMillan", and you'll see why.
