    Stop wasting your time with 285-300g projectiles, your rifle clearly doesn't like them. I tried 285ELDs in my AX338 and they shot like shit (almost 1.5-2" at 100m).

    Factory 250g Swiss RUAG, my AX338 does this all day, every day...

    Not saying it does this every time but it is pretty damn close. If I use high end Bergers with 250 grain scenarios, I have shot 0.3 MOA at 300 yards on more than a couple of occasions. I don't reload.

    Good luck OP...

    I'm guilty of a fair bit of bubba smithing on some firearms, but taking a saw to an AI just feels so damn wrong.

    Also, I definitely don't sell any of my bubbas....

    I've had mine loosen before, too. But you can feel it "clunk" when you pick it up, even if they're just a little loose. I'm not sure how much it affected accuracy as I wasn't noticing a problem, but I wasn't shooting for groups either. It sure can't help though!

    Then yesterday, this thread was on my mind when I was shooting one of mine, and it reminded me to check them again. They were tight, but I found a little play in the key slot screws that hold the Pic rail section for the bipod. That gun has an Elite Iron bipod and the mount covers up the front rail screw. Of course I had the wrench for the key slot screws (in the stock), but for some reason I didn't have the wrench that fits the bipod screws, so I couldn't remove it to access the front rail screw. The bipod had a little wiggle in it because the rail itself was wiggling in the slots. I just tightened the rear rail screw that I could access, and carried on without issue. I found it before I started shooting, and I haven't noticed an accuracy issue prior, so I don't know if there was a measurable effect on accuracy. When I got home I got the right wrench and removed the bipod. Rear rail screw was already starting to loosen up again because the front screw was still loose obviously. I grabbed the manual and looked for a key slot screw torque value but couldn't find one. I tightened them up by feel as much as I thought I safely could and re-installed the bipod.

    Out of curiosity, does anyone know of a published torque value for those keyslot screws?
    I want to add that parts can be enough loose to move around and still not make a "clunk".

    I noticed this when my rimfire rifle was benched and I zoomed on the scope. I saw the image wiggling as I watched through the scope. But my hand could not feel any movement of parts. I could have bet 500 that the part was not loose, but there it was. I had not even noticed weird grouping, in use it probably settled and then stayed pretty much still.

    Since that, I have of course always torqued every screw until I hear a loud SNAP.

    Ok will go this Saturday to the range. Will swap over scope ( scope and rings together as one piece). While scope off will check.
    Do you thing I should just tighten or loosen and then tighten. Is that part bonded on the axmc.??

    You guys are just mad because a 12 moa shooter owns a AI. The best part of this thread is theis actually taking time to search all his past posts to prove his point
    Thats pretty typical here..theis is quick about it but others will go digging too.

    Stop with the “your rifle doesn’t like xyz bullet” or other load stuff.

    It’s probably almost impossible that it’s strictly shooter error or load error.

    I don’t think one could actually do this via either without purposely trying.

    I once shot the cheapest browning x bolt in 7mm rem mag you could buy. I was helping a friend sight in his hunting rifle.

    That rifle made me it's bitch shooting 180 Bergers at 2930 fps. I probably had a 1.5 inch group at 100 yards. Never again. I think I shot 15 rounds and Id had enough. Kudos to you guys shooting those 338 Lapua Mags.

    To be fair those cheating bastards all use muzzle breaks. 7mm Mag/300 Win mag is about the most you can tolerate w/o one.

    Eh. There is a lot of movement so you have to manage recoil properly to shoot well, but honestly that 7 Mag hunting rifle you were shooting (typically light, and no brake) was probably a lot more punishing and challenging. A heavy, braked 338 is more of a heavy shove with a longer impulse spread out over more time (milliseconds), vs. the swift, sharp punch you probably experienced.

    I would be happy if it could do 2 moa with factory.
    I would expect it to do sub moa with good factory rounds.

    but 50 meters and you see what it did.
    At the test last week it did get better.
    they said it did under .75 moa ( That was 3 shots just three shots)
    To me you would need to shoot 3 rounds 3 times at least to say it shoots sub moa group.

    thank will let you know how it goes.

    I wish I were there to give it a go. It is highly strange. I have shot mine sub MOA out to 600 yards with a variety of factory ammo. Some does work better than others but it is never dramatically different. I don't reload so I have no choice but to characterize a bunch of factory ammo. My experience is that any cartridge using over a 285 grain bullet is to be avoided. I think 300 grain bullets are too heavy for this caliber. 90% of my shooting uses ammo with a 250 grain slug and the results always put a smile on my face.

    Due to COVID, I haven't traveled to a longer range as the nearest is 3.5 hours away. I would not anticipate any difference though aside from my own limitations

    Thanks rub it in.
    It is great to see.
    You are running fast. I was getting around 2680 speeds.
    Ok will try and find them. It can not hurt. Thanks.
    Not rubbing anything in.
    And that's not running fast, that is the normal expected factory 250g speed.

    Try listening to AI owners who have 338LMs and experience.
    XYZ bullets are very relevant. I could never get the 285s (factory or handloads) to shoot. At best they were 1.5" at 100m, and it had nothing to do with the rifle or my shooting ability (got a few Army International Medals).
    Combine a projectile that doesn't shoot well with an inexperienced shooter and you have terrible groups.
    FYI our Military along with many others use 250g projectiles in their 338LM Sniper Rifles. Do the math, slow high BC doesn't equal better.
    As for my AIs 'Pet' handload I'm shooting 250g SMKs at 2985fps with an SD of 3.
    20200111_182129.jpg
    Now -.338 bullet diameter...
    And that's shooting prone with a bipod that does NOT hop.

    Can you get factory Lapua 250gr Scenar .338LM ammo there in Australia to try out?
    You'd only need a box or two.

    Ok getting so light projectiles 250grain and 265 that I have.
    Did some 300 grain loads as per the previous test last Sunday.
    This what it shot now
    To take the shooter out of the equation three of us are shooting it. Two are competition shooters.
    I want to thank Harveyn for coming out and having a try and helping.
    This time it shot a lot better.
    The only thing that has been changed has been the barrel taken off and then screwed back on.
    The muzzle break has been taken off and on.
    It has now shot more than 120 rounds.
    20210228_100010.jpg

    From the left:
    Second row second box and 3rd are with norma 300 grain. I shot the second box that was my fault must have pulled the last shot.
    The fourth row second box and 3rd box are my loads of 300 grain Sierra. I shot the 3rd box.
    The 2 boxs at the bottom right are 3 shots each of the 265 grain projectil (my load).
    Anyway it is shooting realy better than before.
    We all have no idea why it is shooting this way now.
    The only thing is maybe the barrel cleaned out or fitted correctly with the refit.
    For now that is it.
    Oh shot the gong at 512 meters. Did 5 shots and got 5 hits ( they said the gong is 6inches i will go next week and measure it ).
    Waiting for some factory ammo 250grain.

    Yep would be good.
    I am starting to think it might have been me. But it did the same to another shooter. But it has been getting better.
    Now it shoots better.
    I give up I have no idea.
    I got 5 shots at the 6 inch gong at 512 meters so that is ok.
    Will try lighter projectiles too.
    I looked at the crown again and that has smoothed out a lot.
    I have no idea but will check the next 100 rounds. It is much better now.
    Thanks for the suggestions. A lot of the boys recommend going lighter and I will go for the lighter.

    I did like the way the 265 were grouping. Those groups were rushed groups too.

    Just get some time behind the butt.
    It's all learning, which is part of the fun.
    Once you've found a load that works for you, keep it.
    Sadly, too many people want to swing their cocks around, instead of help.
    That's what happens when Individuals forget they were actually part of Teams.

    Must be amazing when a bloke can fly the plane, and fall out the back at the same time.

    I don’t own an AI but this site has a wealth of information, Frank did a video on bipod hop. It is worth looking up along with all of his videos, I will look up his videos when I am having a problem and if I practice what he preaches my problems go away. Hope you get your rifle to shooting.

    All this and you STILL haven't posted a video of how you are attempting to shoot this thing, not even a photo of how you address the rifle.

    JFC, bipods do NOT hop.
    If you are hopping your bipod (don't know how to load it) then the last thing you should be doing is burning cash behind a .338, you will learn nothing and continue shooting 5+inch groups at 50m.

    Get your head out of your ass, get a shitbox .223 savage, get some training, work on your fundamentals, get proficient and then MAYBE think about having another go at your AI.

    Magnum cartridges and precision rifles are NOT for motherfuckers who still hop their bipods.....

    Ok just try and follow. The gun shot much better now.
    I shot the same as the competition guys do.
    I am having a gunsmith have a look at it as well.
    I don't have my head up my arse.
    I might have a lot of issues to deal with on it but definitely not up my arse.

    I hope I don't offend the others that have been a lot of help.
    A lot of points to look at.
    Some of you here know that this gun was shot by one of the best shooters in Aus when we tested on the Sunday test. It shot 2moa. That is after the checking and taking the barrel of and cleaning the contact area.
    The load development that Luke did got it down to under .75 moa.
    As it was getting shot it was getting better.
    Which makes me believe it might have been the nip on the barrel which is now smoothing out.
    That's why getting it check by gunsmith just to confirm.
    Also very good points the guys that asked to check 250 grain projectiles. Have done the 300 smk. So will try the lighter grain.
    Will be testing this Friday and then will post and end this post.
