Yeah, I know you're right Chap.

I don't plan to shoot Blackhornout of the Omega anyway- didn't get any better accuracy with it than I get with T7 in that gun, and I'd rather swab between shots than clean that Blackhorn varnish off of the breech plug.

It's just that I WANT to see what it does in the Mustang, and modifying the breechplug should do no harm as far as shooting other powders with it. I have half of my first canister of BH left to play around with. I'm really wondering if it might give me better accuracy with the Mustang than I can get with T7. In theone sessionI shotwith .25 ACPsI got groups that "almost" equaled my T7 groups, even with delayed ignition on every shot. I'm wondering if instant ignition will give me fantastic groups. If not, there will be no more BH purchases for me.
