Some advice on fitting chassis to shooters?

[Rprecision]

I am setting up a new chassis. I have adjustments for: length of pull, cheek height, recoil pad height and cant.

Brand and manufacturer completely airside I am looking for some tips and tricks to getting everything adjusted.

I havealways had a hard time finding a adjustment that works in all positions. I can get the fit perfect in prone, but moving to a bench or standing off a barricade/tripod the eye relief seems to far away.

Conversely if I set it correctly for standing I find myself trying to move back away from the scope while prone.

I'm 6'03" 230, with long arms if that matters.

How do you make all this work?

Thanks

There is no perfect solution.

I set my rifles up for upright position (standing, sitting, barricade, etc.) because that is how I use them most. But, I set up the scope as far away as possible, so that is at the edge of scope shadow. Then, when I go to prone it is at the other end of acceptable.

For the stock without adjustment, I put the length of pull comfortable in the upright position as well. I find it easier to have shorter length of pull in prone than having longer length of pull when upright.

That requires carefully setting it up and ring positioning.

Pick one and stick with it and deal with the sacrifice in other positions
or
Put it in the middle and makes smaller sacrifices in all positions.



Six of one, half dozen of the other. You have already deduced that nothing is perfect for all things, now its up to you to choose.

This.
Mine are optimized for prone because that’s 95% of what I do.

Logger Head adjustable check rest is raised 3/8” for prone, bottomed out for upright. Length of pull not adjustable so same for both. Scope positioned for prone as that is 95%+ of my shooting.

I’ve never needed to adjust height of comb while switching between positions... ?‍

That doesn't seem to be my problem, I can usually work around the small change. Its primary a eye relief problem driven by length of pull.

Tomorrow I am going to try and find some middle ground as others have suggested.

As a side note, I always thought this problem was isolated to me........glad I'm not the only one I guess......

Lop, put the butt of the rifle in crook of your elbow (bent at 90deg) you should be able to grip the rifle and get a finger on the trigger correctly. I used this as a starting point and typically like if a little longer than this.

Get behind ther rifle in a correct prone position, close your eyes, relax with your face on the cheek rest and then adjust to the correct height for your scope.

Now, set your scope as far back as possible to you before you start getting black in the sight picture. Level the reticle and lock it in. Revisit your cheek height now that your scope is set and adjust if necessary.


Throughout the day keep coming back and getting in prone and make sure it's how its supposed to be. Ive set mine up like this and has been fine in all positions.
