I've got one in 243 as well. I've only been able to shoot about 30 rounds so far. I screwed up my measurement to the lands so the bullets were all jammed, apparently not something this gun prefers. I will say this though, I had several bullseyes, just couldn't get it to stay there. It's really for my lady but, I'm overall very pleased so far. I know it'll shoot once I get my loads together. Definitely worth the money.
