So supposedly there is a new sniper ammo called MK316 mod 0 that is replacing the 118lr. Supposedly federal is making the ammo using IMR 4064 and some speculation is that is the same load as the federal gold medal match. I attached a copy of the supposed spec sheet I found on the internet. Is any of this true? Also what is the performance of this accuracy wise vs the 118lr. The reason I ask is I have a rifle that shoots very well with FGMM and duplicating the load might save me some time and money.

Is this the same data sheet from the discussion on Snipershide? If not, look it up as some guys have been using 4064 and if I recall correctly, results have been good. I think there is a PPT show saved as a PDF in that same thread from Panama City that breaks out the details for this and 300 wm as well

I use 4064 in my .22-250 with excellent results but I have never tried it under a 7.62mm. Maybe I will give it a try...

4064 is a great powder. Give it a try.

Iv been using 4064 in my 30-06 since 1989 with great results. My load is 50. gr IMR 4064 with a Sierra 165 gameking or 168 match king with Lapua brass and Federal 210m primers. I was using 50.5 with magnum primers but found it was a little warm on hot days. Always work up and refer to your manual of course.

When I was shooting in a local competition many years ago ie mid 90's I used 44 gr varget 168 gr sierra matchking lapua brass and 210 m or cci benchrest primers in my 308.

I used to sort my brass etc etc bit when I discovered Lapua and started to sort by weight I found out I did not need lots it is so close in tolerances.

Fast forward a few years ago I got a 308 that shoots best with Federal GMM. I have not been able to produce handloads that shoot as good as off the shelf GMM so I am trying to find the load they use due to cost. I am hoping the new military sniper round made by Federal is the same thing. If so big savings for me. Unfortunately I don't get enough trigger time anymore to keep my skills up to par.

Yeah, Have to agree Lapua brass is hard to beat...

New to competition shooting, does anyone have an opinion on Sellier & Bellot 308 180 Grain @$18.85 20 rounds, seem a good alternative to BH 175 gr for match 6 & 800 yard ranges.

It depends.

I don't think it will prove to be as consistent, and hence less accurate, but try a box or two and see if your rifle likes it.

The proof is in the tasting, right?

Same here. After finally achieving sub 0.5 MOA with gas gun, I don't want to switch to other ammo and mess the mental game. I am looking for cheaper alternative though.


175 gr 7.62x51 FGMM is the right ammo for me. Prob it's in my head and bias from when I didn't know what I was doing, but the 175gr .308 FGMM did not produce the same result. My issued M118LR did not do as great as the 7.62x51 FGMM either (likely due to me as the weakest link).

I'm looking at the IMI Razor Core

Anyone ever tried this out of bolt and gas up to distance?


The price is right, even better than palmetto;s great deal with free shipping for 175 gr .308

Penn, all the above are cheaper than Widener's offering

This AB39 stuff is the heat. I had the opportunity to take it to a sniper-observer course and use it. I also attended the same course a few years earlier and used 118LR and then transitioned to Gold Medal match in the middle of it due to inconsistent grouping with the 118 (I know...switching in mid-course was not the best idea but it worked wonders for me; my groups shrunk significantly).

The AB39 performed just like the Gold Medal match. Great stuff - IIRC, Jeff Hoffman helped the development (or developed it) but others took the ball and ran off with it; it's been a few years so don't quote me.

I have been wondering about this ammo company as well. Have not purchased it yet, but the 5.56 sounds really close to mk262 clone. If not better. They have several match types in quantity.

Cheaper than black hills too. Classicfirearms.com has it in stock from time to time. GB also has it, but about 30 buck more expensive from sellers. Seems like a lot of quality for such a cheap price.

Hopefully I will get a range report of it up in the summer days. If it is good I hope a lot more gets imported in 5.56 and 7.62.

Just picked up another pound of IMR4064 and some 175mnSMK's.
Been reloading this week while waiting for my barrel to get threaded,

going to load up some MK316 using the 41.7gr recommendation.

been using IMR4064 for years.. its simplifies my logistics. I use it for my bolt gun..for my M1A , and for 30/06 for my Garand,

Its not one of the latest and greatest...but it's always on the shelf at $26.99 a pound or $199.00 for the 8 pound jug.

And it is consistent.
