Hey there. Certainly appreciate the work you put into these videos and quite good quality. Where I disagree in calling this a "Fail" is that this is not in any way determined that the gun is a fail and just as likely if not more, could be a number of other issues. As a content creator there are certainly best practices. First, when you are doing any type of accuracy testing, you are not going to use an unknown optic on that system. Have you used that Diamondback on 338 LM or other like calibers and have shot great groups? Are those rings checked out? Not sure if you are an individual or a store, but you out of all people should know that the optic is probably the most important part of that system. Get a GOOD scope. No one says you have to buy a ZCO, S&B, or a Razor Gen 3, but spend at least $1,000 to $2,000 for a known good scope that you can use for testing going further. Even more critical for the rings. Rings shift, bend, etc. 2. You sure as hell DO NOT use hand loads for any type of accuracy testing, especially without working up a specific load. For accuracy testing, get or buy quality match ammo that can be also purchased by others, use Hornady Match, Lapua, Barnes, Federal Gold Medal Match, etc. S&B is NOT match ammo and has certainly blown up guns before. You are using some fairly light loaded ammo and somehow that is the determining factor for accuracy? Did you pick that number out of a hat or was that load worked up and proven out with a ladder test and picked based on accuracy nodes? This is why we baseline test with quality factory ammo. It may not be the best, but it is replicable. Finally, shoot this prone. Gun was jumping quite a bit and your load into the bipod was inconsistent. Some shots you had moderate pressure, other shots almost none. When you are shooting as you were, with no bag rider, you cannot free-recoil it. That is why, shoot prone. While I have not shot the 338 LM, I was at a Ruger event where they took 15 brand new 300 PRC rifles and we just started shooting them out to 2300 yards... with factory ammo, no break in, and they were all very well under 1 MOA, in the hands of numerous writers with varying levels of experience. My own 300 PRC RPR was sub MOA as well with a variety of loads. 2600 fps is quite a bit slow, unless those were 300s that you were shooting. Generally i have seen them shoot better loaded a little warmer.... but again, this is why you do ladder tests and look for nodes.
I was coming down to comments tomorrow or less say the exact same thing in a lot fewer words thank you on behalf everyone who I'm sure shares the exact same thoughts and opinions of he never gave that rifle a fair shake
The cheapest ammo is five dollars a round. But he actually said five hundred dollars, not five hundred rounds. ___ 2 months later I realized I need to edit this because the cheapest ammo that I found was $3.40 around. I snagged 3 20rd boxes of it.
Ruger grossly over-torques the muzzle brake for some reason, at least that was the case with mine (300PRC). Reefing on a muzzle device can cause the threaded section to stretch, distorting the bore diameter at it's most critical point, throwing accuracy to hell. Breaking it loose and resetting it at a more human level of 30ish ftlbs may take care of your issue. Mine was installed by ruger's hydraulic gorilla and removal was a heat-and-beat nightmare.
You look really unsteady/uncomfortable behind the rifle. You're also inconsistent in loading the bipod vs sometimes not. I think this rifle would perform quite differently with another shooter
Don't know what your gun is doing but the one I have is great. Try the 250 grain. Can't really say anything bad about the Ruger. Don't like the cost of the ammo but the rifle is great.
I am guessing this fella needs to try some different ammo types and figure out that rifle wants, or...many other RU-vidrs are cherry picking what they upload regarding this rifle.
Probably need to try different ammo.. I buy several different brands and weights before I say the rifle is bad.. could be that scope. Didn't think diamondback tactical would be rated for 338.. had one on my 308. But definitely try different ammo
Could be the gun. The vertical stringing makes me think its the scope. My .338 lapua had an arken ep5 slide back in the rings 1/4" across 2 range trips and my groups looked just like yours. I ended up buying nightforce rings and the problem was relatively fixed. Ive never shot an RPR but usually you hear good things about them.
I dont have an issue with mine find wat it likes to shoot. 3 shot moa groups im happy with my 6.5prc and the 338 laupa I own in both excellent accuracy
stringing shots vertically do some seating depth tests I never have any luck with factory ammo work up a load do the seating depth testing and find what it likes.
