Yup, and this becomes a variable. I'm happy as long as I'm 10% accurate (hoping I am).

Then there is the question, the machine checking the accuracy, when was the last time that machine was calibrated? and who calibrated that machine?

We had this issue with radar guns in police work. Who calibrated the analyzer to check it's accuracy, and who checked that? Came a point where the judge said if it's checked by a calibrated device, that is good enough.

I've often wondered that lol. How much 'drift' or 'creep' there was overall in metrology devices used by the NIST. Is theirs right? Checked by whos? lol

We used to have to lap our rings for a precise fit, just to show you how far things have come fast. I still have a ring lapping kit that goes up to 30mm, which is also kind of funny, because I don't think there were any scope tubes bigger than that at the time... Old

Even for those that do own a torque wrench, when was the last time it was calibrated?

But, but, who calibrates the Calibrators?

And who calibrates THEM?

Trigger tech diamond. I’m still firing forming brass so I haven’t trued up the data or shot for groups at longer ranges, but it’s hammering a 1/3 ipsc at 624 yards. It’s such a fun little round, suppressed it’s really quiet and no recoil

The Badger rings

Hey, would you take $1,000 and my Garmin Xero C1 Pro? If not, I’ll just buy it after I sell it.

Back in '84 I made a 50yd shot at a 'Stompers' replica German tiger tank with a Mini-14. The bullet ricocheted just in front of the tank and tiny fragments tore through the plastic, making a look like battle damage. So cool looking that I've kept the Stomper tank to this day.

The discipline is called metrology and a properly calibrated device should be able to demonstrate that its calibration is traceable to the National Institutes of Standards and Technology.

That’s how all the “who” and “how” questions you brought up are answered. If not traceable to NIST then you’re fooling yourself.

BUT, NIST traceability costs and certification must be regularly redone. And no, we don’t do that…well, maybe someone who uses tools from their work place that has metrology in place.

I send my Vortex torque wrench back to them every year or two for calibration. They do it with no hassle. I don't even call them. I print out their service form and send it in. Generally I have it back in a week or less. I also had the pleasure of seeing their calibration equipment before.

The LW17 is the ADM QD Mount

A few years back my brother, a buddy, and his two sons were shooting on my parent's property in northern IN. I showed up about 30 minutes after they had already started. We had a 6x10 steel target about 400 yds out hanging on a fencepost and I'm not sure anyone had taken a shot at it yet. I pulled out my Armalite AR-10 chambered in 308Win., laid down prone, and cracked a cold-bore shot at that steel plate....DING!!!! I know I know...not a challenging shot but the moment was cool. My buddy said his sons still talk about that day.

Where did that thread go? BOOOOOOOO!

Bump

I thought i read somewhere in this long thread that using Ai mags causes the round to not slip under the extractor and losing the controlled round feed design. Anyone with an ai conversion can confirm or deny that?

Let's get this moved.

Hi all, my husband and I are just having a few beers with our neighbor, and he is on his way into the military so pretty sure he will be joining the forum. I noticed that most of the women in this thread are 20 year old models so hope no one mine if a fellow member (55 yo) goes topless for everyone out there View attachment 8703128

Not sure if we’re being trolled, catfished, or hell…maybe…just sincerely being entertained, but I approve this message!

IMHO, there are a lot of positives for having the TBAC RR cans in hand now.. IF suppressors are removed from the NFA, they will be even more demand for them, making them even harder to obtain. With the removable Brake, there is the potential for TBAC or other, third party replacement end caps in all kinds of configurations. Might even be a robust secondary market for them, especially the HUB RR cans. All speculation on my part,but a few positives to consider.

And in my case our communist state may just outlaw their sale or impose some huge tax on them

I just went through a similar evaluation. I ended up with an 18" 6 Creedmoor.

1.) Availability and lower cost of dies (quick search, you can always save money in the PX)

2.) The larger case capacity worked better with the powder I have on hand. I have 14 powders between H4350 and roughly H1000, and only one keg each of H4895, AR Comp and Varget.

I like having options, and Quickload showed 98-100% burn in the 18" barrel for all 14 powders, so "slower" burning isnt really a concern.

Well, this is an important wrinkle in my situation and maybe I should cancel my Magnus RR and my 338 GEN 2RR

I surely don’t want to be holding a $2000 piece of titanium that is outdated six months after I receive it because the big beautiful bill passed and removed silencers from the purview of NFA and now we can mix and match parts as we please

Exactly. I know that my tool certainly have gone byby. But the tools are still valid “target points” for me on how hard do I twist the wrench get say 20 lb/inches. My old hand no longer has that calibration setting.
