Hand tight.

I confess I've been a bit anxious about my Tikka's prefit being put on at 75 ft/lbs. I didn't put it on and would have to spend a decent bit to get a vise/torque wrench/action wrench if I wanted to do it at 100 ft/lbs though. Is there a good way to test whether it's an issue? I remember Morgan Lamprecht and some other guys testing chassis issues by hitting their barrels with a rubber mallet to see if it would zero-shift due to improper stock/action contact.

It’s fine.

Name a more critical fastener on your rifle than that one which contained 60,000psi plus of pressure.

I dont know about this line of reasoning...We see hand tight barrels work fine, but no way in hell would I go hand tight on my scope base or rings. As long as the headspace is correct, you dont even need all of the threads on most tenons to be able to handle standard pressures. Consistency is the main reason for the torque discussion.

I am still in the camp of people should do their own testing, or crank the fucker down if you don't want to test and never think about it. One of my rifles gets a snug of a wrench, one isn't coming off without access to a vice.

Maybe I missed it previously but are you using a suppressor with this upper?

Try and measure how much torque it takes to thread that barrel out with the set screw still tight. I bet you max out your torque wrench.

But why?

I get your point, don't get me wrong. I'm just stating that one doesn't have to crank a barrel into the receiver with simian-like strength and intellect in order to retain zero or prevent a cold bore shift.

$250

What height is the mount?

But the threads/shoulder of the fastener are still not loaded in tension, or at least not “proper” tension for the “fastener” size.

More critical for what?

I can promise I’ve seen FAR more issues from improper scope hardware and stock screw torque than barrel torque.

About the screwdriver found on the roof.
Was it the shooters or left behind by a maintenance guy? Flat head, Phillips or torques? Maybe an allen head driver? Does it match the type of screws for removing the action?
My guess is that it was used by the shooter to gain access to the roof. He previously scouted for the shooting point and how to gain access to it. He didn't just show up and make a plan on the fly to shoot Kirk.

Gaining access to the roof was as simple as hopping over a railing. It was so easy a cave man……………..

Next M14 project for anyone interested: replica of a 1990s era Navy “Grade A” double-lugged match rifle with a vintage (early 1990s) Navy stock in the unique “battleship grey” that McMillan made for the Navy. Hope to have it built by Forceman out in AZ this autumn (welded-on front and rear lugs w/ torque screws, mounting a 1993 dated USN marked heavy barrel, etc):




Note unique inletting for rear lug with pillar-based torque screw set-up:

…just a random project update for anyone interested in the old M14 platform.

In keeping with the theme of this sniper rifle forum, I also did some work to my replica Navy M14 PSSR sniper rifle recently. I decided to mount my old school working AN/PVS-4 night vision optic, since I had the rifle out of the safe and had removed the BPT scope mount. Ergonomics are kind-of poor/suboptimal with such a high position, but that’s the night vision optic what was available in the 1980s-90s-early 200Xs. FWIW, the M14 scope mount for the PVS-4 came in packaging dated 1987. Note the weight w/ PVS-4 (which by itself weighs 4.5 lbs).





…now, if I can only get my old PVS-2 to work…

Well then try pushing the ELDM'S deeper. Try 50, 60 and 70 thou jump or until the crunch gets too much. Might work for you as well.

I did not see any velocity increase going from 20 thou jump to 70 thou jump with the 155 ELDM.

I've had better results with them closer in two rifles. My 308 has an m852 match chamber. At book length with the 178 eldm I'm only jumping .005" It shoots them pretty well if I get a consistent batch.

In my winmag with the 208 eldm, I couldn't get them to cooperate from .020"-.100"
Tried .010" off and we were on to something. At .005" it shoots .3xx

Maybe it should be blamed on OPEC...

Thought it was common knowledge that the dinos theory was BS.

Remember the gas rationing in the 70's, 10 gallon was all you got.
Think about that in those cars.

Have you tried deleting and reinstalling the app? Seems you are the only one with this issue...

That's probably why area 419 don't sell it as a kit anymore. I've wanted one for a while but decided I'll never be able to justify now so I'm trying to come up with a different option. Pity no one else makes something similar.

Bingo. Our jaws and bushings haven’t changed in price at all. Before we started selling this kit it was a relatively unknown vise, and when we promoted it they had to increase production drastically to meet our demand. The price was then ratcheted up pretty quickly, and the terms to be a reseller became less and less favorable for us. Smaller margin, larger commitments, longer lead times, etc. Apparently it was far more trouble to make than they were initially charging for.

We would LOVE to still sell them at some version of the original price, but it’s just not possible.

I’ve been in the same situation. Rain started half way through a 10k and I was lucky to have it. (It was damn hot)

Only issue I had was fogging/drops in my shooting glasses. I had to look over them. Had enough water spots on my ACRO that I had to wipe the lenses half way through the pistol section due to multiple red across the sight picture so I was getting on the trigger before I was actually on target.

Goes without saying, dry cloths and shoes. Maybe some warm soup at the car if it’s going to be cold.

Embrace the suck.

I’m wheels up Thursday for a 7–ish K DMR R&G in NC. Kids are going to run it too. Supposed to be 80 and windy with full sun . Good shit.
