Another tragic trip to the range with the Kimber of Oregon custom classic On todays menu was 19.5gr of 4198 with the 53gr Sierra. Minute of coffee mug. 22.5gr of 3031 55gr Btip, minute of shot glass. 25gr Win 748 50gr TNT minute of silver dollar 24.5gr H335 50gr TNT minute if silver dollar. I can't get 2 rounds to touch each other unless I bang them together in the box. All shooting was done from front and rear bags at 100 yards. Scope is a 4.5-14 Zeiss conquest. Next on the list of powders to try are Re7 and IMR 4895. Maybe I should just buy some 322? On a happy note I have my CZ Kevlar dialed right in with 55gr Btips abd 24.5gr of 748. Thanks greg | ||

If it is that bad, I doubt if changing powders will get you there. Is the scope a known accurate scope? Great brand and likely good, but thay all can have a bad one. Any chance the scope mounting is loose? Most likely in my view is that it needs bedding and the barrel floated, if it is not already. Good luck. NRA Patron member | |||

And the cartridge is....? Sounds like a .222 from here, but am not certain. In my .222s, I use either 20.5 or 21 grains of 4198, or 20 grains of AA-2200...all with 50 gr. bullets and they shoot great. If yours is a .223, I'd think your load might be a little on the light side, as some seem to like near max loads. My country gal's just a moonshiner's daughter, but I love her still. | |||

i just have never had good luck with tnt's in 222 i use either rl7 or h335 & usually a 50 gr vmax or nosler bt, but if you're having troubles like this try a 40 gr bullet or the 52 gr sierra match. | |||

Well, if it's a .222, you should be using H322  (that'll start the yelling) but as accommadating as the .222 is, something obviously is wrong that needs to be fixed before burning any more powder of any kind. I'd take the rifle apart and put it back together making sure there wasn't errant wood or metal chips lodged anywhere and that everything that should be snug is snug, etc. I'd take my scope mounting system completely off the rifle and use a little brake cleaner on a Q tip to clean out the screw holes and to clean the bases and screws abd put it back together with a little lok tite. Trying another scope with a proven track record wouldn't hurt. Then I'd try about a 75-80% load of H322 and a 53gr Sierra MK bullet. (that's a flat based bullet) That may not be the best load you'll find, but if it doesn't get you very, very close to MOA at 100 yards, I'd either be on the phone to Kimber or I'd sell the rifle. If your groups are as bad as you post, there just isn't any magic bullet or powder that is going to suddenly start giving you one holers. Aim for the exit hole | |||

Most of the time Stillbeman is right on the money, and he probably is right in this instance too. Still, I have had one .22 CF that shot just like you're describing with your .222, but then eventually shot 60%-to-80% smaller groups when I found the only powder it seems to give a damn for. One of my Hornet's, it simply would NOT shoot under 2-to-3 MOA or so with any Hornet load I had seen recommended, or whipped up myself. But when I finally tried a case completely full of AA-1680, it became a reliable 0.5 MOA shooter, with no alterations to the rifle. That probably won't happen in your instance, but it MIGHT. You'll never know until you have tried everything, both mechanical and load-wise. Sooner or later, you'll probably identify the problem and get it fixed. Don't give up the ship! | |||

Fasteel, I'm not a gunsmith or even a guncrank. However I've owned a number of different rifles. I don't know if this is a new kimber or how many rounds you have down the tube. I have a love/hate relationship with kimber. I've owned six. I have three at present, the ones I have kept are montanas, 325 wsm, 308 win and 260 rem. All shoot under an inch with certain handloads. Here are some things I do with my Kimbers. You may laugh, or you may try it. It won't cost you anything but a little time. First I adjust the triggers to break at 2 lbs. Next I make sure the barrel is free floated. Third, I take either a piece of index card stock or a couple of folds of aluminum foil and place between the action and stock where the reciever contacts the stock. I cut them to fit and use a drill bit to drill a hole in the shims for the stock screws. I then tighten the screws. Finally, I grab a half dozen bronze bore brushes. I screw a brush onto a coated/graphite cleaning rod. I always use a bore guide. I coat the brush with a jb bore paste/kroil mixture and run it back and forth through the bore for about fifty strokes. Usually after about 50 stokes the brush will loosen up. I pull it out of the bore, and unscrew it. I'll put on a jag and patch and run a couple of strokes to get out the old bore paste and repeat the process. I do anywhere from 100 to three hundred strokes. If its a new rifle its kinda like hand lapping. If its a used rifle it will certainly clean the barrrel. The above routine has worked for me on Kimbers, Sako and Remingtons. I also do the bronze bore brush/jb/kroil on all my new rifles as my barrel break in routine. I have three 222's at present. Two sako's and a rem 700. A load that shoots sub inch in all three is 50 gr. nosler ballistic tips, 25 gr. BLC-2, 2.210 OAL, Rem 7-1/2 primers. Best GWB | |||

Bed it. My M700 in 223 would pattern at about 2-2 1/2 inches with anything I fed it even after installing a Douglas barrel. Finally ordered a glass bedding kit from Midway for about $30 and it now shoots 1/2 to 3/4 MOA with anything I feed it.

Boys I have found out what my error was. A while ago I bought a bunch of brass, mixed headstamp, from a fellow on line and when I started to go through it all I found more than 150 of these were already primed,sized, chamfered and ready to load. So load them I did, for my load development for my new Kimber in 222. The rookie mistake, I didn't realize that because they were all different headstamps they would all have different volumes, so there fore different ignition, and providing groups that were all over the place. I looked at the stamp on a group that I shot yesterday and all 5 were different, an Imperial, a Norma, a F C, an R P and a Win. So I have some new brass , neck sized and I use the same data with Win 748, 22.5gr, 50gr Btip. Loaded them up and off to the range I go. The first group looked OK, the next group was getting better with bullets actually touching. Let the rifle cool for a few moments then fired the 3rd volley. I'm here to tell you this Kimber is a great shooting rifle. Nother lesson learned, Thanks Greg | |||

Thanks for the tip GW, Montdoug told me the same thing with the JB and Kroil mixture as a barrel helper. I'll give that BLC-2 load a try as well I have some of that powder. Regards Greg | |||
