New ladder test results.I have conceeded, New barrel is needed.Last post update.

Nice set-up.
I have had great results so far with Retumbo and 285 Hornady's; wont include the recipe right now but it works in my 338LM, which is based on a M995 action, custom 30" barrel with 1:9 twist. Good info in Hornady Manual 13. I cant use the clip that came with the action as the OAL is too long for it. Its a single shot now, which is just fine.

Your doing the right thing - keep going - the load for that beast is out there some where.

FWIW - Fresh targets, record load data on each target, shoot at least 5 rounds per set. Keep your targets and data in a binder for reference as you work.



:cheers:
 
I never did try the 285's, aside from the factory offering.Maybe they may be the next step.

I keep everything on spread sheets and scans of targets on the computer.

Not a problem.

I did bed what I could, which is not much on this chassis system.

Good marksmanship is a combination of rifle and shooter. An important part of this equation is the melding of rifle and shooter, like a solid cheek meld to the stock when the eye is aligned with the sights.
I would have no idea how a shooter could meld with that rifle, so anything I said would be meaningless.

I think H4831 is trying to tell you he doesn't like your rig.
 
I prefer this over my 7WSM BLR on the bench!!

I actually find this system to be extremely comfortable with hand position and head cheek position in relation to the scope.

How is the recoil? I had mixed results with a .338RUM. Sometimes it drove tacks, then the next it was a 2-3" gun. Chaulked it up to just being uncomfortable to shoot.

Just an observation, but you have six holes down and three up.
Click up a kupple three and that should set you 'bout average for elevation.
I note that all holes are to the right of center.
Remove the right cap and try three clicks to the left.

Post updated target.
That chair is missing some back support.
Not sure if this has any bearing or not of holes in target.
Git yerself a stool so there is no disputing back support.

Not seeking a PO # on this.......proceed at will.
 
Scope bubble is on the opposite side and now have lower rings , that is last years pic of the bench set up.

Believe you me, I have done everything under the sun to eliminate the machine being the issue.

How are you adjusting for cant error without a scope bubble and the scope being that high above the bore?

I'm really unqualified to comment accurately on this but mabye someone else who is can add to this; your rear bag is cocked off diagonally from where your rifle will travel through recoil. I have read that this can be a problem and the theory seems sound to me, though I have never actually put it into practise - I have a hard enough time getting all my poop in a group to get a shot off, nevermind intentionally throwing a wrench into things for experiments' sake.

It might be a tracking thing, Kelly. You never know.

That was the photo just as I set the rifle down before any shooting took place.I do however see that having it off center may cause grief.I do ensure my setup is all lined up an as comfortable as possible.I use this setup for all my load development.Rifles all seem to align and track with the rests well.

I can't remember all the powders you have gone with Kelly but I remember this "exercise" from last year with this gun. Any chance you could try a faster powder? I know with mine I wanted Retumbo,H-1000 or 869 to work as there was lots around at the time. After they all gave not bad results I figured I would try RL-22 as Hornady had this powder listed for the 285 bullet. As they say, Bazinga! After reading and researching on the net I was surprised, no one was using RL-22, everyone is using charcoal speed powders with great results. It ain't stoopid if it works.
