Well at least you have a Kimber. Mine (Stainless Gold Match) went back to the factory for the second time two weeks ago and I have no idea where it is. With all the fighting going on between the dealer, the sales manager for Kimber, and the custom shop guys, everyone is pretty well pissed off at each other. I e-mailed the custom shop but they don't even bother to reply. I am going to e-mail the custom shop and sales manager again tommorrow. I'd at least like to know where the pistol is at.
When I had the pistol and it was working I was getting somewhere in the neighborhood of 3 to 4 inch five shot groups offhand at 25 yards with yeloow box UMC and white box Winchester 230 grain ball ammo. Nothing spectacular, but not too shabby either. If I ever get the pistol fixed, I am confident I can come up with a quality reload that will better those group sizes. You should be able to find a good load too.
For instance, I have been complaining on this board and over at Glock Talk about a G35 I have that just won't shoot better than about 3.5 inches at 25 yards. I am on the waiting list for a BarSto pipe. A couple of days ago I found a target load with 165 grain Speer FMJ and TG powder that shoots scary tight. I am going out in a couple of hours to try some more loads with the 165 FMJ loaded with TG, AA7, Clays and Power Pistol. I am confident I have found the right bullet, now all I need is to find the right propellant.
The reality is that few shooters (and I mean darn few) can shoot better than a 3 inch five shot group day in and day out offhand at 25 yards. It is nice to have an accurate pistol, but unless you are an accomplished shooter and plan on competing, I would think something in the neihborhood of 3 inches should be considered very good.
