Ruger 345 Accuracy

[Dovebuster]

I have two Ruger 345's. One is as accurate as can be, but the other scatters rounds in a 24 inch circle. I know they do not have the barrel bushings that you could accurize like the Colts. Is there anything that can be done to accurize. I suspect it is a problem with the raised section on the end of the barrel for lockup or the barrel (fixed bushing?) on the slide. Any knowledge or recommendations will be appreciated. I really like the fit, feel and shooting characteristics of this pistol but I can't have it around if it scatters rounds like this. It also Jams more often and on more types ammo.
PS. I have tried 3 different types ammo. RN & FMJ 230grn & FMJ 200grn.

Call Ruger first, then send it to Ruger with detailed information....they might help you out. I have sent then a pistol--Mark II pistol--in the past, and they fixed it for the cost of shipping it to them and sent it back to me.

Thanks. I'll give it a try and let you know what happens.
