Re. B&P 12 ga comp 1 shells. I've shot 2 different lot#s of the 7/8 oz 12 ga Comp 1 load in a Perazzi DC12, 2 different W&S 700 series guns, a Piotti & a CSMC 21 w/o an issue. I did recently hear of someone finding a 12 ga 7/8 oz Comp 1 shell w/o a primer.
I like that load a lot & if there is any difference in the headspace (rim thickness) between the Comp 1 & the 2 1/2" 12 ga High Pheasant which I've also had no issues with & shot a lot of in different 12 ga guns I'm unable to measure it.
Both of those loads are on the Gordon type hull.
BM, it's not rim thickness, it's diameter that is the culprit. See the above thread link for measurements.
Best, SRH
