Got my first experience with it today! I ran out of BH209 so i loaded up speed loaders with 100gr American Pioneer 2f and headed out with the 250gr Powerbelt Aerolite to sight in the Konuspro 275 scope.

First thing i noticed, ZERO crud ring with the BH209 plug and Winchester W209 primers! I mean NO crud at all. Super easy loading. I pulled the plug and the rifling was all clean as well with no signs of baked on residue.

What gives?!! The original flat face QRBP gives me a bad crud ring with American Pioneer.

Really? I never tried it with anything but BH. Do you have any T7?

Just pellets and no store has any T7 is stock.

She shot good off my wobbly table! I got her dead center with the 75 yard line in the scope.

Pellets give a crud ring no? Give them a try.

Try some Thors.

bad crud ring. I cant shoot them with the BH209 plug though.

Why not? It's just like the Omega plug, and it works with pellets.

Then again. It's my barrel. Maybe you shouldn't.

exactly LOL.

I tried APP powder in several TC guns including Triumph and an Omega, I shot it for 2 years and never had a residue problem of any sort. I finally decided to give up on it as it was difficult to measure with a volume measure and when it attracted some moisture it was very erratic and I live and shoot on the down wind side of Greers Fairy lake which is a 44 thousand acre lake so the humidity here is high all year round.
Evidently the efficiency of the breach plug makes a difference in the residue as the only powder that is really nasty to clean here is 777 and there are only a few who don't have difficulty with crud ring.
