Jerry assked,"Do you guys have to resize the RMC hulls? How about the mag tech?"
Only if your chambers are different sizes and if that is the case RMC can engrave the shell base with an identifier of your choice. Or, RMC will make you a re-sizer.
I have two 20 Ga. BSS's and their chambers are identical, which allows me to shoot the same brass hulls in both guns
Mag Tech hulls are for Black Powder, use large pistol primers and have over sized internal dimensions necessitating the use of card and fiber wads. Double Hammer, a now defunct company reamed out Mag Tech primer pockets to accept 209 primers and inserted an inner base wad. It has been my experience that the inner base wad fails after very few reloads and either disintegrates or becomes lodged in the barrel.
One of the positive aspects of loading RMC hulls is the consistent patterns they produce. Yes, I know "them's fight'n words, but for what ever reason, the patterns are the best that I have ever experienced. And to compound this ridiculous statement, the best patterns were achieved with card and fiber wads. Dave Casey the original RMC owner told me that the case volume allows for better patterns because volume is not lost due to crimp folds. Others think that the lack of crimp folds does not disturb the shot as it leaves the barrel. To me, that would make shells that have roll crimps pattern better than those that don't. Anyway, I don't know the reason(s) I just see the results. Anyone else experiencing great patterns?
