Was at the range today shooting my Accura MRX and had an interesting observation.
100 grains of tripple 7 - Primers kept expanding and getting stuck in the breach. Had to pull them out with my leatherman
100 grains of white hot pellets - clean primer, no blow by what so ever, primer came out as normal. This made me say hmmm.
Dropped the triple 7 - down to 90 grains and had the same result at the white hot pellets. Basically zero blow by and no stuck primers.
I was shooting cheddites which I know are on the short side. What what actually causing this with the stouter charge? Is this a head space issue? Would using o rings fix this? Looking to understand the “why” behind this.
Also it’s interesting the triple 7 seems to have a bit more power than the white hots.
Another interesting observation, up until this point I’ve been shooting all powder and even pellets with the BP 209 breech plug. I didn’t think this was an issue until I switched to the conventional breech plug (wasn’t shooting BP209) all of a sudden my groups were way more consistent and much tighter. Can anyone explain why this may be? Was the BP 209 breech plug causing the primer to blow the charge forward?
