3 - 10 shot groups ** updated **

[KDX]

I finally got out to shoot a bit today and shot 3 groups of 10 rounds each (100, 200 and 300 yards) with my factory (except for a trigger) unbedded Savage. I used different brass and primers from what I normally used and might try the 'regular' load next time out. I'm going to take it out of the stock one of these days soon and take some pics of the areas that the Accublock makes with the receiver and see if the opinion is to bed it or not. You can see full fairly even contact on the receiver, so I'm interested in the replys. I might try to 'tune' it before that and shoot this load again to see if it gets better. 68gr Hornady HPBT with 25.6gr Varget.

looks like your on the right track, but it looks like you have a lot of virtical spread.. being a facotry rifle its hard to tell if thats the rifle or the load. i would tweak it around a little and see if you can bring it in a bit tighter

I went out again today with the same ammo and tried 'tuning' my gun as per this article. I started at 10lbs and went up to 25lbs in 5lb increments. 5 shot groups

Being the smart guy that I am I didn't take a driver along so that I could back the screws off. I stopped at 25lbs and will have to go out again for some fine tuning around the 15lb mark. I'm thinking this technique might work on any make of gun with a bedded action. Based on the pics of the contact area between the stock and the receiver, would bedding even benefit this rifle?

im assuming you have the accustock on your gun? in which case, bedding can help, but there is a "few tricks" to be awear of when bedding the accustock, not that i know them only what i have been told when i thought about having mine bedded. but marks on the receiver generally indicate pressure points, which is what we dont want, a bedded action wouldnt be showing thoe marks as the whole action would be supported

deffinatly looks like around the 15lbs mark is where you want to be! im hoping you have all the action screws at the same torque? stressing the action with 2 different torques on the action screws doesnt seem like a very good idea to me :/

 

[KDX]

Yes it is an Accustock. The front two are 30lbs as per the article and the rear is different. After thinking about it I'm going to go to 30lbs on the rear and see how that goes. I wonder if the 'tuning' is changing the harmonic balance on the barrel.

Bedding would be a huge aid as you have almos no contact with the bedding in the stock.

that grey smear is powdered alum from the chassis. Not a good thing for long term accuracy.

When you need to torque to make a gun sit in a stock, bedding is definitely needed.

NO matter how tight you make it, it will eventually loosen and as the stock/action/bolts wear, it will be a moving target.

But what it showed, is that once bedded properly, accuracy can be very nice.

yes thats exactly what the tuning is doing, by tightening the action screws differently, your adding dtress into the action, this stressing of the action, will put different pressure on the barrel threads in different areas (we are talking like 10 000ths of an inch) and this gives the "tuning" effect. does it work, yes clearly id does, should it be done , IMO no, a properly bedded stock with the whole action supported this tuning wouldnt work

Agree with Jerry, bedding will give you a consistent platform to tune your loads. I definately see the benefits to tuning your action screws, it just makes more sense that a properly bedded action is more consistent and has a wider range of tune.

Sounds like Jerry is going to be getting some more money from me again. I've been thinking of a barrel swap also.
