OAL is 2.815 and just fits the magazine without a spit to spare.

I'm betting its 748 because even if it is match ammo federal is still going to make it as cheap as they can, your paying 23$, its costing them less than 2$.
I stated in a previous thread that Sierra once stated that 42 gr of R15 duplicates the 168 Fed Match. I have done a lot of testing on this with 3 different Mil Spec Rem 700's. 42 gr. of r15 or 43 gr of IMR 4895 will match factory loads velocities (Oehler 35) on the nose and produce exact POI's at 200 yards. From the looks of the two powders and comparing it couldbe R15.

Re: Federal 308 Gold Medal Match Powder?

I just wanted to my 2 cents. I have Remington 700P (Police version with 26" HB 308).
I found that 43Gr of IMR 4895 is giving me about the same velocity as FGMM with 168 SMK. (Both measured approx 2605-2620 by Oehler placed about 10 feet). The Primer is also Fed 210 Match.
But the group is better with 42Gr (at 300 yards) with smaller velocity (2510-2530). I mean it is better than FGGM too. So depends what are you looking for, is to duplicate or exceed it.

The 2n part I played with is OAL. I measured my chamber and it is a way long., around 2.925" (with 168 SMK). There is no way I can sit the bullet close to rifling. Even if I do it 0.050" off (2.875") I can pull the bullet out of cartridge by hand. I'm using Redding busing neck die with 0.336".
I tried the standard 2.800" to 2.820" with 0.02" step. THe results are very inconsisent. The length goes always up and velocity is going up and down. The conditions are the same. I shoot 5 for each to have a better statistics (better than 3). 2.820 is my mag maximum. I'm not sure I want to experiment more with the OAL (at least for my rifle).
Is anybody have similar abnormally long chamber? Any thoughts?

Yes, my Milspec 5R is similar. I tried 168 Berger VLD but had to seat them too deep (for magazine) and did not get acceptable results so the 168 SMK over 42 gr. IMR 4895 is my target load. I am also using the Sierra 165 SBT over 42.5 gr. IMR 4895 and get almost an identical poa and only have to adjust 1 click left windage elev is same.

My seating results with all of my milspecs and a repro M40 are exactly the same SD yours.

Re: Federal 308 Gold Medal Match Powder?

I just bought another box of 308 Federal Gold Medal Match 168 gr SMK bullets from another dealer. They didn't shoot as good as the last box so when I got home I broke one of them down. I had already noticed that the first box had the green primer sealer around the primer and the second box didn't. The powder in the two shells were not the same. The new powder weighed 42.7 gr. instead of 43.4 gr. and the grains were .003" larger in diameter and almost twice as long. The picture below left is of the original powder and the one on the right is the new powder.
It's no wonder we can't figure out which powder they use. They use more than one type for the same shell.
I bought some Reloader 15 for the SMK 168s. At least that way I'll know what's in my shells.

Re: Federal 308 Gold Medal Match Powder?

I can't see a high quality picture from my droid, but the smaller grain on the left looks to be Varget and the one on the right is an Imr from charge weight I say 4895, it could be 4064 but that's a very tame charge for there stated velocities, but they do not look anything like alliant powders, atleast not on my phone.
