308Loader,
Did the sound and recoil feel different on that round? I ask, because that is so slow, I suspect a measuring error caused by unburned powder particles tripping the first screen ahead of the bullet getting there. What distance is the chrono set up at?
Shadow9mm,
The trick is getting rid of throat unevenness. Most new revolvers seem to have their chamber throats all reamed by different reamers. A standard accuracy trick is to ream them all to SAAMI maximum to iron that out.
How much it costs depends on how you get it done. When cylindersmith.com was still in business, IIRC, it was about $35. A better price came up when a friend returned a Ruger Redhawk to the factory with a complaint about its accuracy. I owned one that had five chambers that would shoot into under 0.7 inches at 50 yards, with the sixth chamber always opening it up to about 1.5". It was because of that gun my friend bought his copy, but it wouldn't stay in 6" at 25 yards. When the factory returned the gun, it came with a shop paper saying "cylinder reamed". It shot fine after that. So if an argument can be made regarding the accuracy and you can measure the throats, you may be in a good position to argue for free factory service.
This fellow is recommended by some users at the castboolits site. I have no idea what he charges.
You can rent the reamers for about the price cylindersmith used to charge and do it yourself if you are used to tool work.
