I believe I have confirmed my Quigley load.
75 grs old E 1.5, br2 primer, Jamison brass, muzzleloader specialty drylubed felt wad .446 rubberized cork wad, powder compressed to seat the short tank buster into the case about .4. 8lb seth cole patch treated with jojoba oil after the bullet is loaded.
Long story short 10 out of 12 rounds into the upper right quadrant of the 4-8 steel target from 800 yds, blowtube only for fouling control.. Also the .434 accurate bullet shot well, only using 1 wet and 1 dry between shots. But at this time it's not going to replace the KIK 1.5 match load.
Very happy.
Tried some loads with the 2f Olde, but the jury is still out on that, but the cases are sure "clean" , now just need to see if I can find some real accuracy with the 2f.
I can see another order of Olde Eysnford in the not too distant future
