Concern? or not?

Hi all..........a buddy of mine gave me a couple packs of CCI primers for 12 gauge. Reloaded AA hulls with 19.2 grains of IMR700x and 1 1/8 oz of lead in a WAA12 wad. Got through the first pack of primers and noticed they were indeed CCI209M!!! The IMR load tables do not list any recipes with 209M primers for 700x powder. Is this a big concern or, a stupid oversight on my part with room for forgiveness in that they are useable?:redface:
 
I wouldn't shoot them.

Your load with standard primers is at the top end for 700X at over 11,000PSI according to my books. Adding the magnum primers to the mix may drive the pressures even higher.

Magnum shotshell primers are meant for slower burning powders than 700X. I'd slap my forehead and start taking the shells apart.

You now have 100 shells to cut open in order to salvage the shot and powder.

The 209M will cause a large spike in pressure with that load. If you do decide to try shooting them I would suggest pulling the trigger with a very long string.
 
Thanks for the insight. I've yanked the shells. That was a long and arduous task I hope never to repeat. I've been reloading now for about 7 years and this is the first real screw up I've made. Right is right and there is no room for assumptions when it comes to reloading and shooting in general. However, Alliant does indicate recipes for red dot with CCI209M primers and green dot as well. So, this would indicate they can be used in conjunction with powders of the faster variety. Alliant lists a charge of 20 grains for green dot which is just below the burn rate of 700x which is what I'm loading now and red dot is even faster and the data is there for CCI209M primers and red dot. I know IMR does not list a recipe for these primers with 700x and that alone is reason enough to not go there. Makes one wonder though why red dot and green dot can be used and 700x cannot.:confused:
 
The answer is likely that none of the powder companies can test ALL combinations. When you use a "book" load, you know tthat it has been tested exhaustively and found safe. Going off into the wild blue yonder might be fun, but it could get waay too exciting. Stick to the load tables.
