A few hundred shots!!!! You must have a shoulder of steel. Have fun breaking in your new gun

In my 1/48 T/Cs I shot 100 gr loose Pyrodex and the T/C maxiball with great accuracy. I had bad luck with Maxihunters.

The QLA of my CVA Mag Hunter measures 11/16".

cayugad,
nope it's not. not only a little but 10" groups. Started with Triple Seven and switched to Pyrodex Select. Using maxi-balls but they are not T/C.
Switched to Power Belt and things got better but did not have enough of them to figure it out.
