Re: limbsaver de-resonator ?
I have tried to do a load work up on 2 rifles with the deresonator on the barrel (customer wanted it left on). Both rifles I could not get any loads to shoot well. They would not follow normal shot paterns you would normally find when working up a load. I asked to take it off, and repeated the loads, and found great shooting loads in both rifles. I won't do load work up with them on now.
But, if you only shoot factory ammo and need something to try and tune the barrel to the load, I would think this would work. You would have to adjust the deresonator up/down the barrel and shoot a group and see how it did. But, how reliable it would be in varying temps would be nice to know.
