Yeah I see min73,500-max78,500 same as the old 8448509 and that is what Hornady said their proof loads should be, apx 78,000. I stopped machining bolts in 2017. There are several companies I would not buy bolts from just reading their description and since I have a history with and know I can trust Microbest that is what I would buy and sell if I needed bolts. There is no need for me to try to find a HP tested bolt like the OP only to find out the company made a mistake and sent one that was not HP tested. I don't care how it's done but if you put 73,500 psi on a bolt face you will see the results of it.
ETA- I would rather buy a bolt from the real manufacturer than a reseller who may sell a different brand every month but laser etches their name on all of them. It's odd I never see many companies advertising AO Precision, Microbest or LW Schneider bolts

Not only does SOLGW check all the boxes but they also tell you specifically what those boxes are instead of just saying mil spec.
Checking all those boxes and sticking to a proven formula and being transparent is what I like about them. And that combination is very rare in this industry.

You won't outvote the corruption.
Sic Semper Tyrannis
I sold direct, Maxim does, LWRC , pretty sure JP does, Y/M , Aero Precision, LMT, Sharps, I'm pretty sure those companies make their own bolts and sell them.
Resellers should tell you who made the bolts instead of sticking their own name on them like they made the bolts.
What do you think of this? https://arftac.com/microbest-ar15-5-...roup-complete/
If you don't like Microbest don't buy them but if you buy Rubber city, spikes, toolcraft, PSA, Y/M or any nitride treated bolt and wont buy a Microbest you may want to dig a little deeper.
Microbest makes the same parts the same way for every customer, they don't change anything for anyone. They have part numbers, you send in a PO for the part number.
In 14 years I talked to the VP twice, he said they make apx 40,000 bolts a month and 30,000 carriers, they make all the small parts to build complete BCGs along with many other small parts of ARs. They make mil spec parts for many companies and you're right the are mainly concerned with filling big orders but I could send in a PO for 200 bolts or 144 BCGs and they will fill the order.

I don't know anything about the reseller but if it's a microbest BCG it will be good to go.
I think any bolt from AO Precision, Microbest or LW Schneider will be good. I'm not sure who makes BCMs bolts but the tool path on the bolts looks like Microbest. I would also trust LMT.
If I feel like working I can make my own but if I'm buying it would be from one of those 5 companies.
