ARGH! I need a new barrel... My .22 Waldog is shooting great, but for sporter class, I've gotta shoot 6PPC, and my 6mm barrels both appear to be sorta shot out... I haven't been able to get 'em to group better than 0.250" and worked with one of 'em all day yesterday, trying out Benchmark powder...
If I had more money, I'd be shooting a new barrel...
