Well now!Just got back from the range after shooting this Ultra light. I had ordered 3 different slugs but only got two ,I guess one was out of stock. Shot some 2 3/4 " Remington buckhammers just to get started.Sighted gun in about 1 1/2 " high at 50 yds. Shot 5 rounds and brushed out barrel then used a clean patch a few times. Moved out to 100 yds First shot from clean barrel was about 2 " high and 2" right,secnd shot was 2 " high and 2 " left. Next 3 were 2 " apart right in bull. Tried 5 of the hastings 3 " laser accurate. Ended up about 3 " low strining from left to right of target. I am resting this on frame and not forearm. So don't understand stringing. Shot a few more of the buckhammers with good results. One thing I didn't try was cleaning barrel after every shot. I was cleaning every 5 shots Tried a couple at fifty yds offhand,dead center of bull. Then just for giggles with a fouled barrel I tried 3 shots at 160 yds which is the max length of our range. Held dead center in bull put 3 shots inside 2 1/2 " perfect windage 8 " low. This was with the buckhammers. Don't really think I have to try anything else. When I shot this the other day I had a couple OF FTF issues.When I got home I could tell that with the transfer bar up when the hammer was down,the firing pin was not coming out all the way. Took a little material from front of hammer where it hits the frame when down. Had no FTF events today, so hopfully that will do it. Now all I need to do is make sure where first round goes from clean barrel and I think this one is ready to hunt. Have been using a 50 caliber huntsman for a few years. Now it has a mate. Oh yeah So far I haven't been seeing much leading, Although I have been brushing barrel every 5 shots or so. Alsredoak
