Model 10 LH accuracy issue 308

[Kmrere42]

Hi,

Working with a new to me model 10 lh in 308,  Shooting some M118 specials @ 100yds I have groups that are 1/2" wide by 12 - 14" tall.  This was after re-doing the crown and groups 3" wide by 20" tall.  The stock is tight to the action and the scope mounting is solid.  I am thinking bad scope,  but I would like other opinions.

Stock is wood and the barrel doesn't touch.
no bedding in the stock.

The rifle appeared to have been fired very little by the previous owner.

Scope is a simmons 3x9x40 Blazer

?? Is this a package scope from Savage??  as there are no iron sights.

first why did you redo the crown and who did it?

the up and down strings do not sound like it is the scope but could be. it sound More like you are resting the barrel on something hard or flinching.

I did the crown myself,  I work in a decent shop with good tooling and if I ask the Boss nicely, I can do pretty much any type of project.  The factory crown was polished a little lopsided and looked off. 


I am shooting off a bench with lead bags front and rear, trigger is at it lowest setting and I am really trying to do my part.

are you resting the barrel or the stock on the front bag?

The crown could still be a  part of the problem if it isn't perfect it can affect the bullet.

The toe of your stock isn't touching the bench when you fire, is it? Just a thought. I saw a man at the range right after deer season started that couldn't get his rifle to group for anything. I watched for a bit and saw that the toe was touching the bench when he fired, causing the rifle to pattern rather than group. I loaned him my bags and saw to it that the stock was supported properly front and rear and he put a respectable group without any scope adjustments at all.

[Kmrere42]

The stock is clear of the bench and I am supporting the stock under the swivel screw. 

This seems strange to me as most of the time if I have a bad grouping rifle then the group is all over the place, Never in a tight vertical string.

all screws tight?

try putting a small piece of paper between the forend and the barrel to make a pressure point. you can try different places and heights.

Sounds like inconsistant ignition, take a look at the fireing pin and all the stuff inside the bolt and see if it is properly lubed and nothing is binding and that it is setup properly with the proper pin protrusion.  Vertical stringing is most likely not a crown problem.  Larry

Try supporting the stock with the swivel screw in front of the front rest, not touching it. It made a difference with my model 12.

Remount scope bases, something is loose to get 14" of vertical.

[Kmrere42]

I will be redoing the bases ans switching scopes to see if that if this is where the problem is.



Will let you know after the range.

Had a good time at the range,



I had put the rifle back together with a known good scope and I was a little frustrated when it started to do the same vertical stringing again.  I gave it some choice words and gave the stock a good thump on the bench and shot this.

It looks like your rifle could be a candidate for a bedding job. It sounds like the action was not seated properly in the stock. If it is a newer rifle, I think it is pillar bedded already, but the action may still be hanging up some where on the stock. Check the bottom of the recoil lug to make sure it is not getting hung up or the action is not getting hung up some where else. You can do this by taking a bright colored crayon and coloring the stock in the action area, then re-seat the action and taking it apart and look for spots that are rubbing more than others. When I tighten up action screws I snug both down with the first one being the front screw. I then really torque them down starting again with the front screw, then the rear screw. Good Luck and Good Shooting.

BTW - a much improved grouping.

[trotterlg]

I still vote for cleaning up the inside of the bolt, but the Savages have a plastic trigger guard which the rear action screw seats on.  The action is pillar bedded but the rear screw cannot tighten down against the steel pillar because it has the plastic trigger guard between it and the pillar.  The front screw seats against the steel pillar. My solution was to replace the trigger guard with a steel one.  The recoil lug may also have a gap between it and the stock, so a little bedding between the recoil lug and the place it contacts the stock would not hurt.  Larry

Hmmmmm,



Where do I get a metal trigger guard??


I really do hate plastic.

That is where I got mine. When I was talking about tightening down the actions screws I forgot that yours would probably be plastic I have two Stevens that I have modified, both have the stainless steel trigger guards. I also replaced the bolt handles and recoil lugs with stainless steel ones (blued are available). I like the BT style bolt handles. IMHO I think it gives you a smoother feel while working the bolt and feels good in my hand.
