Hello Folks,
Yesterday I shot this group at 100 yards, hand held at the shooting bench with the left hand resting on a block of wood. The 66 caliber balls weigh one ounce, and are propelled by 140 gr of Diamondback FFFg blackpowder. The patch is 0.015” cotton duck lubed with Ballistol. Velocity is 1400 fps. The sights are very tight in the dovetails, and I’m not going to take a chance on loosening them to take out the little bit of right error. It’s too small to worry me. Steve Zihn built this Rigby-pattern rifle for me several years ago.
Take care, Tom
