UMAREX GAUNTLET 2 .25 cal SLUGS at 75 YARDS

In this video, I will shoot .253 35 grain AVS slugs at 75 yards. I will slug the barrel to determine the GROOVE diameter and TWIST rate. I also send a bore scope down the barrel to look closely at the crown, lands & grooves and transfer port. My Guantlet 2 is going to Hajimoto Productions for a near complete upgrade. I will have a follow up video in the near future
