This round is NOT a NATO standard round and it CANNOT be used in civilian weapons chambered for .308 Winchester due to difference in the .308 Winchester and 7.62mm NATO chambers. These cartridges are intended for use in magazine fed weapon systems only. Initial production quantities will be packaged in 20 round cartons, 23 cartons per M2A1, 920 rounds per wirebound box.

98Z5V Posted April 1, 2018 Report Share Posted April 1, 2018 (edited) I can calculate it if we can find a verified velocity from another known rifle. Just need velocity and barrel length. Wash, Mk 319 is different ammo than he's asking about - Mk 316 Mod 0. Here's some good stuff on the newer loadings. No velocity data, though, on the 316... https://ndiastorage.blob.core.usgovcloudapi.net/ndia/2009/infantrysmallarms/tuesdaysessioniii8524.pdf Edited April 1, 2018 by 98Z5V Quote Link to comment Share on other sites More sharing options...

Sisco Posted April 1, 2018 Report Share Posted April 1, 2018 If the range wasn't snowed in I could get some chrony data, since I have a stash of it, But it will need to wait a month at this rate. Quote Link to comment Share on other sites More sharing options...
jtallen83 Posted April 1, 2018 Report Share Posted April 1, 2018 Isn't the MK 316 basically a clone of FGMM 7.62 175 gr or vice versa? Same LC headstamp with two digit date code. Quote Link to comment Share on other sites More sharing options...

Found a couple sources on this basically all saying the same thing; "Final reply from ATK does indeed describe the GM762 as a “commercial variant” of the Mk316. Same propellant and projectile in both." https://forum.cartridgecollectors.org/t/federal-7-62x51mm-175gr-gold-medal-match/10116/10 http://www.m4carbine.net/archive/index.php/t-150170.html Quote Link to comment Share on other sites More sharing options...
98Z5V Posted April 1, 2018 Report Share Posted April 1, 2018 The 175gr FGGM might be the match for it, but this is the "needs" statement on why it was developed. M118LR wasn't getting it done in gas guns. Mk 316 Mod 0 is the recipe that works for the gas guns. Info in pic came from this presentation: https://ndiastorage.blob.core.usgovcloudapi.net/ndia/2009/infantrysmallarms/tuesdaysessioniii8524.pdf Quote Link to comment Share on other sites More sharing options...

That explains why I get better results in my DI guns from the 7.62 FGMM 175's than from the M118LR then. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted April 1, 2018 Report Share Posted April 1, 2018 Early on, I had shiitty results with M118LR in my first DPMS-based 308, with all great parts, built for accuracy... and I stopped buying it. It did well from a bolt gun, but that wasn't why I was trying to get it. I feel the pain, brother. Quote Link to comment Share on other sites More sharing options...

Much more then my reload clones Quote Link to comment Share on other sites More sharing options...
98Z5V Posted April 1, 2018 Report Share Posted April 1, 2018 (edited) This Mk 316 Mod 0 is probably our answer. Or, skip trying to find it, and just get FGMM 175gr ammo. I can tell you this - at every single Desert Shoot that Matt has been at, that specific FGMM performs. Perfectly. He's got a drop chart that is dead nutz on, at every range we've tried it on. @Matt.Cross He'd never shot at 845 yards before. He consulted his drop chart for that ammo, and had a hit on the second round. The drop chart for it was right on. That ammo performs. I was pissed when he did that, because the pressure was DEFINITELY ON!!! Edited April 1, 2018 by 98Z5V Quote Link to comment Share on other sites More sharing options...

I was pissed when he did that, because the pressure was DEFINITELY ON!!! The 168 FGMM is also excellent, but from 500 yards out the 175gr is far easier to shoot with reticle holdovers. And that dope chart was scary accurate, it was generated based on the elevation of the reservation and the expected weather conditions.
