Torque specs for xlr chassis?

[its only light]

Does anybody no if xlr has a recommended torque setting for their chassis's? I worked on some new loads for my savage 338 lapua sitting in an xlr. Every load I tried shot about 1" or slightly over at 200yds. All the groups were a straight up and down line. Im thinking it has something to do with my action torque/bedding. Its not bedded as the xlr has the v block. Any suggestions, rants, info, opinions greatly appreciated.

I've been using an xlr chassis for my .308 Savage for about 3 years. I've taken it apart a few times. As long as I don't mess with the scope I can just shoot as if nothing happened. I've always crancked tight, no specs that I'm aware of.

Hmmm interesting. Back to the drawing board here I guess. Never had so much vertical stringing in every load I tried like this.

 

[Joe R]

Are you weighing each charge or are you using a powder drop?

If using a powder drop you will get more variance.

Im using a lyman electronic powder dispenser to weigh each charge. I may play with seating depths a bit and see what that does for me. What are some other reasons for excessive vertical?

 

[Joe R]

With some powders I have experienced more variation in velocity. Since I shoot a .308 IMR8208 may not be suitable for a .338. The only way to find out is to use a chrony and see what kind of SD you get with your powder bullet combination. Obviously a higher SD would be indicative of a problem that would result in vertical dispersion.

With my current powder and bullets I get an SD of 3-4. I used to get 8-17 with my old powder.

Could you go higher with your charge or are you at max?

Action screw torque is 65" pounds

Awesome. I will try 65lbs. Im way back at 35lbs.

Im working close to max. I found that jumping bullets gave me single digit es and sd. Jamming which I usually do at least to start was all over the map. This gun shot under half moa til i put it in the xlr from the hs is came in. Hopefully tourqing to spec will help me out here.

This is what I use and snap it on action screws and scope rings before every match. 65 pound-inch is appropriate for pillar bedded actions or those with v-blocks. Bedded actions with no pillars may need a little less torque, depending upon the bedding. [br]

put it back in original stock and see if it will shoot 1/2 moa.,,,,if so problem solved,,,Roger

Lol I would definitely do that BUT I sold the stock it came in to help cover the chassis. Im hell bent on getting it to shoot in this chassis. The combination of the chassis and the lra bipod make this thing the most stable and best fitting (for me) setup ive ever owned. I know the barreled action can shoot so think its a bedding issue. The barrel is floated the tang is floated so torque is all I can come up with for an answer. I tried 65lbs. Im heading to the range in an hour or two so I will update everyone interested when I get home.

 

[Joe R]

If continue to have problems with the XLR chassis call them, they are very helpful. It shouldn't need any type of bedding. It is an excellent highly customizable system. I really likemine.

The success I had with it gave confidence to go on to the Eliseo chasssis.

I agree on the quality of the thing for sure. So which do you prefer. Xlr or eliseo?

Well I went out with it again this evening. I shot 5 5 shot groups. I did set front and rear to 65lbs. My first group had quite a bit of vertical and went about 1.1 inch. The next 4 however went into .975, .863, .725, .737. All at 200yds of course. This was running right around 2825fps with 285gr hornady hpbt bullets.

I assume the first groups were a little bigger because I just gave it a good scrubbing yesterday so it had to foul up or whatever you pros call it. At least thats what im blaming it on. Im still not totally satisfied but thats probably pretty decent for a factory barreled action.

What do you guys think. I could push it a little harder and who knows maybe im right on the bottom of the node here. Or would you call it good quit testing and go shoot? I never know when to stop. Ive burnt up barrels load testing and never settling on 1 load even though accuracy was decent. I dont compete and i enjoy testing and improving my ammo.

It's a little too early to give a definitive answer, I've only had the Eliseo chassis two weeks.

Having said that, the Eliseo chassis have a much better finish to them than the XLR. That is the only thing negative that could be said about the XLR, the finish could stand improvement, its too easy to scratch with anything metal, even a bullet or brass case. The Eliseo finish looks to be very durable. My XLR chassis is a folder and that kind of spoiled me because when you turn it 90 degrees allows the rifle to stand on its own for easy cleaning. With the Eliseo I have had to buy a rifle tool box/stand and that works pretty well.

Here's a picture of my .308 with 30" barrel. I'm not a competitor either, but I am slowly working my way towards that. Since most of the competitions are held on Sundays, I may have to play hooky from church once in a while, but to me it's not about the competition, it's about being the best shooter I can be.
