Hey one ton
I am sorta late to the party but I would like to offer my observations.
That is definately a Kimber 82G, I own three of them and love each and every one of them.
Wolf, SK, Eley, Lapua, GECO, most all of the european sub sonic ammo shoots very good in my rifles. CCI SV is a bit tight and closing the bolt requires more effort. I do not shoot CCI SV in my rifles because of this which is too bad because I buy it by the case for my pistol shooting.
You can expect that it will shoot close to 1/2 inch at 50 yards using run of the mill sub sonic ammo, if you test ammo you should be able to get that down to about 0.35 inch or 0.30 inch. well, that is what I was able to maintain with my rifles.
The rifle that shot the worst I kept the iron sights on it and probably shoot it the mostest, I have a butt hook for it and use it for plinking off the front porch of the deer cabin. Favorite target is a old pressure tank at 140 yards or so. You can sit on the porch, shoot the water tank, set the rifle down, grab a potato chip, and hear the ping as the bullet hits the tank.
the other two rifles, I put scopes on them and pull them out every so often. I got Bill Calfee's book (availble on amazon) and using his instructions, slugged the barrel and lapped the two tight spots under the two scope blocks. Kept the tight spot from the front sight block but worked on the rear two and accuracy improved to about 1/4 inch at 50 with preferred ammo (SK pistol Match Special). From what I learned and observed, drilling and taping the barrel for the scope blocks and the front sight mount squeezed the barrel a little bit and it was evident from slugging the barrel. If you are interested, get Calfee's book, take your time, be patient, do a couple laps, slug the barrel, test it, repeat until you do not feel comfortable continuing. Remember, I kept the tight spot at the muzzle to keep the accuracy. Although I got better accuracy, I never got it to equal the accuracy of my winchester 52c but they are still fun to shoot.
I am sure you will enjoy your rifle as much as I enjoy mine.
Regards,
Cranky
