MagTech Primers
Quote from Reloader on December 8, 2009, 7:02 pmI just had gotten 1000 MagTech 7 1/2 pimers from a friend. I am using them to reload once fired Lake City 5.56 cases. I use 24.5gr of W748 powder, and 55rg Hornady FMJ-BT w/c bullets. The cases are swaged with the Dillon Super Swage, and trimmed to 1.750.
I have reloaded 300 and have noticed that the primers sit deep in the primer pockets. Is this a problem? I do not think they are deep enough for the firing pin not to strike them. I normally use CCI 450 primers and have not seen this before.

Some rifle primers are intentionally made with shorter cups to reduce the chances of an accidental discharge when used in a semi-automatic rifle with a free-floating firing pin. It is very unlikely that the deep primers will cause an ignition problem. We have not received any complaints regarding their use, and I haven't seen any online.
