thunderhawk: has a 1 in 38 twist
I shoot a 50 it will tack drive bullet/sabots
Both mine also have a 1-38 twist, I think all Thunderhawks did.
Mine shot PRB with 90 gr Pyrodex P
It shot the 50/40 180 gr 40 caiber Gold Dot and the 230gr 45 caliber bullets close to a minute of angle, and would group the 250 XTP with in 2 inches at a 100yds. I think it is a better all around twist than the 1-28. Lee
