Re: Kimber Model 82 G...Anybody?

I believe that's what they told you, but I think they were telling you a story. Try weighing your rifles and see how close they get to that number. From what I found looking around, it is the weight. I don't think they were measuring group size in mm back then.</div></div>
Well that is a very interesting thought that you have there. I don't have a scale that will measure with enough precision an object of that weight to be able to test the thought though. My postal scale won't go above about 4 lbs and the bathroom scale really isn't any better than +- 2 lbs. When I tested the rifles at the range Friday they did actually end up with the relative accuracies that the stickers predicted they would assuming the stickers meant that. However, since the numbers on the sticker were not even close to the measured results (at 50 yards anyhow) I think that this was probably simple chance.
About that testing, I used CCI STD Velocity, Eley Sport, and SK Standard Plus for the testing. I chose these because I can afford to shoot them regularly and they are the best shootign stuff I can say that about. Each ammo got five, five shot groups per rifle at 50 yards (To be honest it may have been more like 55 yards, it is kind of hard to tell at the range I go to.) I threw out the furthest outlying shot of the 25 blaming it on the admittedly mid shelf fodder. I then averaged the four resulting five shot groups and one four shot group to get the numbers for each rifle for each ammo. Here are the results:
Rifle 1
Eley Sport .576", CCI std .648", SK .87"
Rifle 2
SK .576", CCI std .756", Eley Sport .766"
Rifle 3
Eley sport .65", SK .778", CCI .80"
Rifle 4
SK .59", Eley sport .77", CCI std. .92"
While I was not totally blown away at first with the Kimbers groups, I shot a group after all of these with my Annie 54 and it was on the better side of the represented groups but not the best. I think that the 54 may have some bedding issues but the Kimbers aren't bedded either and their stocks have had 30 years to warp. Performing on par with a 54, even on a bad day, has to be to their credit.
One last note, 2 of the 4 rifles would not strike the primer hard enough to reliably fire the cartridge when using their own bolts. I ended up using the bolt from the most reliable gun for these two. Even that reliable bolt did not strike the primers as hard as I would have liked. The simple fact is that the firing pin springs in all 4 rifles are old no longer sufficient. I think they were all stored cocked. I expect that this is true for many if not most of the CMP guns. A new $10 replacement will be necessary for these rifles.
Here is the best looking target of the day.
