...guns and ammo just did a feature on their gun and is talking about 1 moa consistently including flyers.

5.2 kg though with an MRDS which is a big oof.

A big oof, indeed. 

Thanks for the info.  I don't have access to G&A. 

Is it possible to shoot 1 moa with a MRDS, or did they have a different sight installed for the accuracy test?

I've found the cheapest way to get access to G&A is through an app on my tablet called 'Readly'. It costs about £9 a month here and has saved me a shed load of money and waste of paper in not buying loads of car, motorcycle and aviation magazines, which would only be read once. They have back issues of G&A going back to the end of 2014 and also have a few other firearms related magazines. You can normally get a deal for the first month for free to see if you like the magazine selection. The disadvantages are you don't get a permanent copy and loose access when the subscription stops.

That is a good deal.

I just bought the digital Nov 2021 issue for $5. Some maddening system where you buy it and they email it to you 24hrs later for some unknown reason.

Once it arrives I’ll get screenshots of the relevant TV / RM277 section and share it here so everyone can read it.

Excellent, I'm looking forward to it

I have the whole article as screenshots. I just wasn't sure if you were ok with me sharing them. Since you are, I will upload them later tonight to my Google drive and drop a link in here to that specific folder.

(This avoids Delphi making it an article with print sized well for ants to read)

And here is the article as embed images for those reading on their phone. Guns & Ammo did a great job - I plan on re-subscribing.

Thank you, hombre!

135 gr, 3000 fps - 3600 J at the muzzle

and peak pressure of 65000 PSI, quite lower than the alternatives


From: roguetechie


A very important thing to note is that TV can absolutely ratchet the pressures up if necessary AND they're getting enough of an efficiency bump in a cartridge this size to potentially get a little more MV out of any given peak pressure.

These are both fairly significant factors in making TV case technology one of the safer bets.

They also have their case manufacturing technology streamlined enough to make scaling production doable in a short interval.

I'm not super sold on the Lonestar/GD rifle but everything else they have is damn tempting.

On the note of TV pushing the pressures up, the legacy 240's we have (and the Barrett LWS I'm not so sure on mk48/240L) already have bolts and carriers theoretically safe to damn near 100k psi.

With the wider economic and political situation the way it is, I'd almost be inclined to tell sig and TV to suck it up, take the best of both programs (IF we can physically make enough Delta p cans!), and dump a moderate amount of money turning legacy 240's etc into 6.8 slingers while also doing a pure fleet back end swap to 5.56 and 7.62 neckless in the legacy fleet for anything that really can't do the high pressures.

This buys us breathing room, time to spool up, and hopefully results in people not blowing up guns by trying to chamber hot shit in stuff it doesn't belong in.

If you really want to go full bonus points, make a new standard lightweight link pattern for all the conversion guns to eke out just a bit more weight savings and possibly some long term cost savings too.

There's a few different ways you could do this in stages to make the workload on depots armorers etc more manageable.

Another thing I'd probably look at doing is a new optic or two that aren't quite ngsw fc level complexity but do run digital reticle projection and a ballistic comp onboard or an easy interface to swap the reticles depending on the exact ammo being used.

Here we go, the whole article in full rez links that you can zoom in on:

Outstanding!  Thanks!

Interesting that it shows 50-rd capacity for the automatic rifle.  First time I've seen that anywhere.

So, does anyone have the September issue?  I'm wondering if it shows the weight of the SIG rifle?
