Cleaned the slight residue from primer pocket first.

Bolt closes easier with and without Win209 primer. In the Gen I this gun was the loosest and dirtiest of my 3 DISC based rifles.

Win209 primer inserts, extracts and falls out of the NFPJ adapter very nicely. The Win209 does go all the way in the primer pocket with just finger pressure. The Cheddite appears to have a bit larger OD but it is shorter.

Fired Win209---Spotless and appear near perfect head spacing. Even the bottom of the primer is almost spotless and flawless extraction.

Fired Cheddite--Same as Extreme 50. Some residue on the sides of the primer and flawless extraction.

Im not going to test any other primers for now. I mainly wanted to make sure it worked with the longest primer Win209 (my favorite) and the least expensive primer i can get locally.

Conclusion for now....this is MUCH better than the Gen I in my Elite 45 and better than the Extreme 50 also.

BTW i am using a PR vent liner but i doubt this test makes any difference. The breach and bolt face in both look great after only 2 primers. The Gen I works fine in my GMB54 wiht Win209s so im not going to test it for now.

Thank you Dave and Sabotloader for your efforts
