Just came back from the range a short time ago and might have cured the problem. This gun is stainless with remington's synthetic stock, and after a few shots without any improvement we changed the stock to a mcmillen and had instant improvement. It immediately started to group its shots unlike before, being all over the paper. We are going to order a new stock for it and we'll go from there. I must admit that the stock that's on there is a lot to be desired, kind of flimzy to say the least.
