Doe Dumper
Im 99.9% sure its good but I think Ill just push it up recharge it and reseat it for good measure. You guys talked me into it..lol. Im gonna test this powder too to see how it does. Be the first one I ever re charged from the breech plug end..lol.
I am not totally sure what you are indicating you are going to do, but i think I am reading that you are going dump the powder out the breech - push the bullet up and then recharge from the breech... if that is your thought I would like to recommend that you push the whole works out. The bullet or sabot may have some powder hanging on to it and not all of it may come out of the breech... punch it all out - run a couple of dry patches through the whole thing - re-install the BP and load up normally..
just my thoughts...
