Great hunt!
Love your little Thumpers!
Couple of questions.
110 by weight or volume?
Bullet fit? How tight are your bullets to the bore?
What are your velocities averaging? I have some very old 777 and would like to compare velocities.
I have a 54 Thumper project to get back to,[24" 1-36 twist] been looking at the Accurate 54-477S mold.
I may try some NE 485s in .542.
A .541 gage pin will slide in, but the .542 won't.
Thanks, for your time.
No BS
