Re: New member.. Kimber 8400 300WSM accuracy??

Mike.. Thanks for the reply.. My 8400 is free floated... I am starting to think about handloads. At the gunrange where I shoot, there is a guy who handloads for people. I know that may be a bit risky, but is it safe to have someone hand load for you? (I would make sure they are a reputable source with lots of experience)...... Has anyone had a gun accurized by Hill Country Rifles?? They said that they see about 3/4 in average on the Kimbers after they accurize them. The guy I talked to said that out of the box the kimber is about 85% and their accurizing will bring it closer to 100%. He also told me that it usually costs about half what a normal rifle would because kimbers already come with a lot of the things they do to accurize a gun.

gt1900 ,

I'd have no problem w/someone handloading ammo for me.
I'd make sure he has some knowledge of loading shortmags first.From what i gather'd over at shortmags.org the saum's and wsm's like full length resized brass not neck sized.
If you start out w/top quality components like 180gr nosler accubond/ballistic tip or 178gr a-max ,mag pro powder ,good brass -->winchester or lapua things should come together quickly for you.
At the cost of wsm ammo handloading yourself would pay for the equipment in short order.I bought my equipment and just began by looking it over and must say i was making a mountain out of a mole hill!Handloading is very simple but w/anything you can take it as far as you want.
The thing about having someone load for you -IMO-that would double your time frame on load developement.
I have no expierience w/Hill Country although if they were bad in this day and age they probably wouldn't be in business!
Also lite compact rifles don't shoot bughole groups as well as big longrange hammers do-- of coarse you probably know that.I'd go out and do some shooting at longrange and see how the rifle/ammo stack up out yonder where it counts.
Well keep us updated on things -->Mike

Does Black Hills make ammo for the 300wsm ?

If they do and you haven't already you should try them .

Your Kimber should shoot better at 100 yds than you are getting without having to spend any more dollars on it .

I just finished finding a load for a friends 270wsm in a Kimber 84. I was not reloading for it . JUst looking for the best accuracy out of a factory load .

So as to not muddy the water I won't say what factory load shot best . Just suffice it to say that with 5 different factory loads groups went from 4 inches to 3/4 inch at 100 yds .............................repeatable !

Remember , I didn't say what factory shot best and though I mentioned Black Hills ammo I did not use any of it .

If you do not or don't want to reload then the way to go is to shoot the factory stuff and see what happens . If you think this is expensive just start pricing reloading equipment [img]/ubbthreads/images/graemlins/shocked.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]

Why not try some match grade ammo as well? See how much, if at all, your groups tighten up. If you don't reload and want accuracy, you probably should be looking at using match grade ammo, Black Hills, Federal etc...make some very accurate store-bought ammo.

This will not make your rifle any more accurate, but it will reduce the variability associated with your ammo.

One other thought is to try Tubbs Final Finish and reducing your trigger pull. Also proper bedding job (if not already done), is another thing you can do yourself. If you're looking at 500yds or less I think the above can be done by yourself and you'll definitely see some improvement in the range of 3/4" at 100 yds, but I'd be looking at what you get at 300yds as a better measure of improvement. Of course if you shoot bugholes at 100 that can't be all that bad...

I guess it all depends on how confident you are in doing what you can by yourself first, or if you have the means to have a good smith like Sean or Kirby do the work for you.

Qt1900, How new is your gun? how many rounds have you shot through it? Being a factory gun you might benefit from the Tubbs fire lapping bullets you could ask the guy that does the loads to make some up for you. I have seen this system work well in some factory guns. The point is this is the cheapest thing you can do up front. I do custom reloading for about 30 different people but nobody has the 300WSM or a Kimber. I usually require the gun to come to me then I build a load for that particuliar gun. I would say try the tubbs first I have used them on several Factory rifles and have always had good results.
As far as gunsmiths go Kirby has alot of happy customer on this bord, I have never sent one to him but I understand he is good his replys on the board sound like he knows what he is doing, I figure I will give him a try in the future. Other than him I have used a guy in colorado name Ray Montgomery he is good and fast. He has always been able to do what I want and will do as I ask I look for certian things to be done and He does it not problem, for example if I want a throat long , short or small to a particuliar measurement he will get it done. Depending on how much money you are willing to spend you might change the barrel , I am not sure who makes the barrels on the Kimber but you could put a Lilja or a Krieger on the rifle I know this would help I will add I know you can reload and do better than the factory 99% of the time. The factory loads rounds that will fit within the SAMI spects if your gun is at the top of the scale the ammunition is at the low side. This can cause accuracy issues. In the future when you get more time you might want to consider handloading

hope this helps, RH

Re: New member.. Kimber 8400 300WSM accuracy??

I have had very good results with factory ammo, so far. I don't have enough brass from shooting at the range to start serious reloading (so I just ordered some). However, after I replaced my scope with a much better one, my groups for 3 or 5 shots are generally less than .32 inch, .5 inch max. My problem, I can see my pulse as my rifle twitches to the right .5 inch or so and have to time my shots accordingly. Your rifle is a really nice one, it should do far better. I'm shooting a Sako A7 in .300wsm and also had a muzzle brake put on by High Score Gunsmithing that reduced the recoil to that of a .243.
