    Hey guys I was doing some work on my 7 MM LRH and I noticed that part of the aluminum block towards the rear of it, the block at the back mounting hole is rubbing on the action. It is a little hard to see in the picture I colored it with a sharpie and then just set the action back in hand tightened, you can slightly see where the sharpies rubbed off without shooting but there's aluminum on the action and on the bedding block. I'm wondering if I should machine off .001 +\- to allow the action to sit in the V-block better?

    Any thoughts?

    Also wondering why they didn't make the aluminum wider at the Recoil lug slot to allow more surface area for the lug?

    I have a couple of accu stock Savages and found out that they can be tricky to work with. The first question would be, "How does the rifle shoot"? if you are getting good accuracy, I'd leave it alone. It's important that the action mounting procedure explained in the manual be followed and the action NOT overtightened. If it is overtightened the safety can bind. The risk you could run by removing metal could cause the safety to bind by placing the action too low in the stock. I saw a similiar effect as you, but, since both rifles shoot exceptionally well and hold their zero's, I just left them alone. If they didn't shoot well, I probably would have replaced the stock. I'm not a big fan of the design. iMO.

    Skimbed with Devcon if the fit bothers you that much.

    Greyfox, I was hoping you would reply with some info, I've read a lot of your posts. The rifle shoots okay I'm getting some vertical stringing issues is why I even kind of looked into this. also a third shot flyer but that's happening with two different rifles so I believe it to be me. Although I didn't have the barrel channel opened up quite enough and had tight clearance on the left side so it may have been that. I have been torquing the two action screws to around 45in/lbs and I can clearly feel the front of the action sucking into the v-block. The rear of the action torques up pretty fast due to it hitting on the AL. It's possible this is designed to keep the tang floating, I didn't think if that.

    Is there a preferred sequence for torquing the two action screws, ie the front before the rear? I set the action in the stock make sure the recoil lug is seated in the slot against the back then I tighten bolts up hand tight and alternate until I reach my torque.

    As far as bedding the stock I was going to, but I don't think they produce that much bedding I can't imagine trying to fill that thing up, it's so hollow, there'd be no skim about it. In their quest to reduce weight of the rifle they removed so much aluminum on either side of the mounting bolts that there's not enough to let it adhear to. Anyone bed these rifles?

    I was very excited when I first got this rifle and I still think there's a lot of potential for it. I'm just starting to handload so I think some of the potential will come out if I can figure things out. When I first got it, it shot lights out at a hundred yards almost single hole but I noticed that the stock was touching the barrel in one little point on the forend, like everyone else so I removed it to open it up, and have never been able to get it to shoot the same. That was with Hornady superformance 154gr, I tried some HSM berger loads; it's alright but not great. I purchase some handloads from a friend and they shoot much better, a lot of jump, they are also bergers. I need to get the load info from him.

    There are certainly some design changes that I feel savage could make.

    I feel your stock frustrations, i had a similar issue with mine and bedding did help a little bit. I have had better luck with accuracy at even 35 lbs of torque on mine and between 35 and 45 it did make a difference. As far as handloads go mine likes most powders ok but really likes RE 25 and 33 so far jumping a vld style bullet .065 to .055. Good luck to you.

    Thanks for the reply I'm really wanting to use some of the extreme lines of powder as our temp varies so much. Going out this morning with some HSM ammo that I broke down and reseated for a jump test so to speak. will post results later appreciate it.

    Well I called Savage this morning they said that it is supposed to tough right there I can't hardly believe it. But I did shoot this group, so I think I'll leave it alone.

    I took some HSM ammo that I had and I pulled the bullets and seated them at different lengths, per the berger manual anywhere from on the lands, to .150 off. I don't know how accurate my data is, because somebody mentioned that I would have to resize the neck after I pulled the bullets, but I measured factory loaded HSM and the reseated loads, neck diameters remain the same.

    That is a three shot group then I made a scope adjustment, half minute right, and shot A fourth shot. That is a handload that my friend did COAL of 3.290 which would be .150 off the lands. In this picture the center of the target is a three shot group of HSM ammo "reseated" at a COAL of 3 .290 which would be .150 off the lands

    above it to the left you can see the three shot group of the standard HSM ammo which measures 3.351 coal

    I'll have to get my notebook to give the correct positioning of each target related to which COAL I was shooting but this target is completely HSM ammo with reseated depths. The gun seemed to like 3.441 which is on the lands and .010 off.
    It then opened up and came back in with a good group at 3.290 .150 off the lands. (Center target)

    So it shot good groups with two different ammo's, HSM reseated and a handload. Both were seated at 3.290 which is .150 off my lands. I'm not sure exactly what the hand load is, I will be getting the recipe soon.

    All shots were in a gusting head wind from a bench with a bipod and rear bag. I absolutely hate the Accu trigger will be looking to get somebody to work it over 2 pounds possibly buying a SSS replacement trigger. I feel that is the biggest factor for me getting better grouping but when I do my part the gun seems to shoot I'm excited to continue working up a handload I have my own equipment now so should be interesting.

    From my experience, I doubt that you would see much, or any difference in group size reseating without neck sizing unless the bullets were a a very loose fit. It more likely that ES could be effected by csrtridge to cartridge differences in neck tension. in any case, that group/load shows promise!

    That's what I thought about the necks too.

    So my next question is ;if the gun will shoot with the bullets on or .010 off the lands is it better to seat the bullet long for more case volume, and potential velocity increase? versus: .150 off the lands, Which would be less case volume, if I'm seeing equall grouping?

    I imagine the best plan of action would be to work uploads zero to .010 off the lands and loads for .150 off the lands and look For grouping, ES, etc.

    One thing I will say is this triggers, killing me I have it as light as it'll go I don't have a pull gauge. but I'm going to look for something around 1.5 or 2 pounds

    I have put a rifle basix in mine and like it very much, you can get it as light as you are comfortable with. That and the accu trigger assemblies seem to sell well on here. I would start stretching your loads out a bit and see which one groups better. I bet you will start to see a difference down range.

    Thanks will try that, I have to find some match primers and some retumbo, and I'm ready to load my first batch of hand loads ever, excited, wish me luck.
