We are blessed to have such an abundance of fine barrels available nowadays. So many profiles, lengths, and calibers. I have just one Ed Rayle barrel stocked up, in a heavy bench/chunk gun. It’s 0.50 caliber, 1 in 72 twist, 48” long and 1.5” across the flats. Wish I could shoot it to its capability. Since switching to shooting left handed off the bench because my left eye is much stronger I get targets with all holes touching at 50 yards on good days. Unfortunately those are not match days for some reason! Pretty sure DGB could do it consistently with this gun.
