I bought this rifle to go along with my M1917 and M1903A3 for use in CMP Vintage Rifle competition.  Looks like I will have to sell it.  Jams are not an option.

GunGrunt, please don't give up the ship just yet...  The answer may be just under our fingertips, and I suspect the "Ah Hah" moment is going to appear when no one is looking!

BTW, Para and Butlers advice is right on the money.  Check your OAL, make sure your cartridge rims have the proper bevel... and roll the rifle slightly left and barrel up when loading. 

If you're planning on shooting at Perry, I'll be there on Thursday afternoon (the day before the Roosevelt Match) and I'd be happy to meet up with you and take a look at it.
