Toughest scope mounts?

The crazy part of that is a unit of measure can technically change over time because the standard we use to define it can change super slightly over time.
Except that the true standard for all units traces back to a physical constant that doesn't change. The kilogram was the last based on a physical object. Dig into Veritasium's videos. Search "Veritasium kilogram" on YouTube and watch from oldest to newest. "Veritasium nist" is another good one.

I really don't think the difference in zeroing at 100 vs 102 yards is going to make a difference on your dope. like, i don't think it's measurable. even if you were shooting in the teens

Question regarding the Hodgdon loading data. I entered 140g bullet and it gives a max load of 40.0gr. I'm using 1x fired Hornady brass for the time being as I had over 1500 pieces. Most of the load data I found was using over 41 grains, I have been using 41.2 for the last couple hundred rounds. The data Hodgdon gives seems low or am I most likely using too much powder. I'm averaging about 2805fps with a suppressor (less without) and nice grouping so pretty happy with the results. But, I'm new to reloading so lots to learn. Using H4350 and Berger 140g hybrid target.

Considering Hornady’s original loading was 41.5grns of H4350 and the 140 AMAX I don’t think you will see a problem with your load. If you aren’t seeing pressure and happy with the performance then I wouldn’t worry about it.

I've only seen 2 break like this personally, but I've read plenty of reports of this happening to others. Really a shame. Cool company and a good price point for an otherwise good product. Temps were in the 0°F to -10°F range. Mine went first, then a couple weeks later my buddy's did the same shit.

Thanks for that, exactly as I expected a failure to look and where to occur. Wonder if they got some bad material combined with a design that leaves minimal margin in that area especially if there's some material or process variability.

I may have to turn one of my ARC mounts into a test piece, come up with a test fixture, and subject it to some impacts between say 70 to -50F...

I'll continue to run mine up until I have a failure; at this point they have proved far more reliable than Spuhr for me.

Trump and the surveillance state.

She was the “Fauci” behind the scenes in the White House during Covid. Supposedly Trump was smitten by her and they had a great relationship so this Palantir deal is to be expected given their friendship but a bad program for all Americans.
The whole Peter Thiel thing/JD Vance thing has bothered me from the word go.

But, but, who calibrates the Calibrators?

And who calibrates THEM?

I've often wondered that lol. How much 'drift' or 'creep' there was overall in metrology devices used by the NIST. Is theres right? Checked by whos? lol
Nist goes to some insane precision. Im a person that regularly goes to +-0.0001" and have made offsets of 0.00003" on diameters. Their stuff is crazy.
