I agree with the long barrels. I use 26" tubes and would consider nothing less than 24". Going longer than 26", to me, always seemed a bit sketchy in respect to still using the fast powders that work so well in the .20. I'm curious as to bullet he used, powder and velocity. Any recollection?Go to a long barrel. Buddy built a 20P 30” and does what some say is unobtainable.
