Acurizing my Kimber Montana

One of those rubber doughnut things.

Stevo,

Try seating the bullet deeper in the case.  My Kimber Montana will only group with the bullet at a certain depth.  Using 165gr Partitions and Accubonds it groups awesome using H4350, and w760 a close second.  Sunday at the range I went with a 180gr E-tip and IMR7828SSC.   I'm getting 1/2" groups at 100yds.    Using the same bullets and powders if the bullet is not seated at a certain depth.  The groups go to *censored*t.. Weird.   Finicky little bitch.

I would try upward barrel pressure to tame the pencil barrel beast.

Interesting, that little voice in my head was telling me to try 165's.  I found some but just hadn't got to them yet.  Was using 760 too.  I was going the other direction with seating though.  Trying to minimize bullet jump to .005 & .010".  How far off the throat are you seating?

Here's what I found so far.  Action is bedded SORT OF.  Looks like it was bedded and painted but not tight at all.  Might as well not have been.  Mass production bedding?  Crown shows no dammage.  Haven't got to scrubbing it out yet.  Maybe tomorrow evening.

I just bought a pro varmit in 22-250 and it shoots sweet.

[HawkenBob]

No offence Huntboy at all but that group you posted is as bad as Steve's. Looks identicle to the 5 groups i saw on steve's target. Did you get some better ones?

[HawkenBob]

I guess after studing your taget better seems your just a hair over an inch. Not bad really, and Im sure the gun is new too you it sounds. Keep us posted on your results Huntboy. And again I appoligise. Were used to seeing 30 cal holes. Which would have appeared even better.

[Huntboy]

No need to apologize we all have an opinion, I'm the one that spent the money on it.
I'm the only one it has to please, you are right that was shot # 6,7&8 out of the gun.
Plan to start doing some reloading soon, I'll let you know.

[HawkenBob]

Wow, if those were factory rounds there great. Cant wait to see what it does with some custom tuned ammo.

I don't have any experience with the Kimber per se. But, my 6lb M7 in .300 SAUM shot pretty irratic from the bench too... 1.5" or so, untill I learned to really hang on to it when I shot it from the bench. I think the forend of those light rifles just likes to bounce around a lot more than the standard weights guns.

Also, that slim stock, and high scope mount due to the 50mm scope... you could be amplifying any paralax issues because of inconsitant cheek-weld. You might look into one of the stick-on cheek pads that are available from Sportsmans... they weigh nothing, and would at least give you some type of support.

Hey Hawken... it's a good thing he got the .300 WSM and not the .308 huh? We all know that 300 fps reduction would render those .30 cal bullets completely usless... probably causing them to bounce off the scull of anything larger than a field mouse!

[HawkenBob]

How come all Josh's post say Ignored? You dont know your ash from a hole in the ground Josh. Let me help. The baseball is up your ass remember?

[JoshT]

How come all Hawken's posts say Ignorant? You contribute nothing usefull to the post... and I'm the one who doesn't know anything? Damn man... it was a joke... JOKE... lighten up, in context... it was rather funny.

[JoshT]

I'm HawkenBob's bitch... he's busy with the goat and some velcro gloves right now... I guess I can't satisfy him like I used to. So, I'll come on here and defend him... since he's not smart enough to do it himself.

Thanks Trailer... that clears a lot up for us. By the way... you think you're the only one that knows how to use the quote function?

Phase 1 of bedding complete (action only).  Bedded last night and poped it out of the stock this morning.  It's got a couple of voids that I'm going to need to fix where I got a little carried away with the modeling clay.  It crept into an area that I wanted the acraglass to flow into.  But that's pretty typical of my experiences with bedding.  I'll fix those tonight and hopefully I'll get to try it out this weekend.  Still have some of the Sierra 180 gr BT's left and maybe I could get some 165's loaded up by then too.  I'll keep you all posted.

I've got a Kimber Montana in 325WSM.  You might have seen it in the classifieds.  I tried three different kinds of factory ammo when I bought it and it only liked one of them.  It would shoot a three shot group in about an inch.  I started loading for it and tried about ten different loads before I found one that would group tight. I meen real tight.  A three shot group that looked like I only fired two rounds.  I found out that if I kept bullet weight under 200 gr. it would shoot better.  The best accuracy I got was with 150 gr. bullets.  Too bad the gun dosn't fit me better...  Oh yeah, I also tried three different scopes on it.
