    I have a box of GM308M 168 gr. with Federal Gold Medal Match printed on the label, but looking online, I see only see Federal Gold Medal, Sierra MatchKing. The word Match is not on the box. Velocity is same, part number is same.

    Is it the same? What made them decide to eliminate the word Match?

    LC is purported to be very soft now that FC is at the helm.

    It’s the same. Federal GMM never used LC.

    Sierra Matchkings are match bullets. I guess the question is does this cartridge use Fed 210M primers?

    Thanks. I shot some of the newer, no MATCH wording and it shot magnificent. 3 rounds in a .22 group at 100 yds.

    Now, to see if I can duplicate it with hand loads.

    What do you think? 4064 or Varget and 168 SMK's.

    It's still the same stuff. They stopped calling it match when they started loading some of it with the 185 gr Berger.

    So now we have .....

    Gold Medal MatchKing.

    & Gold Medal Berger.

    42gr of IMR-4064 out of a 24 inch barrel is a good start , it's my normal load for 168gr SMK...

    Edit... In .308 of course...

    I think the issue of temperature sensitivity might, I say might be a consideration. Varget's claims of insensitivity to temp. changes gives it a thumbs up in my book.

    Somewhere there is a chart listing powders by rate of change in pressure per degree of temp F. I can never find it, I suppose I just don't know the correct terminology to do a search. As i recall, Varget is .8% per degree.

    Just got my box from Brownells with two boxes of FGGM 168 match ammo and a box of 168 SMKs to do some load matching.

    First things first was I measured the CBTO of the FGGM and found it varied between 2.226 and 2.230 on the several samples I checked and an OAL of 2.800 plus or minus a few thou. I did not check all 40.

    Next I set up a dummy cartridge using my FF brass drilled and tapped 6/32 and a 168 SMK from my new shipment loaded and found touch at 2.220 which means in my Shilen match barrel the FGGM is .006 to .010 IN the lands. No wonder is shoots so well!

    To confirm, I slid a live FGGM round up the chamber with the bolt out and gave it a firm push. With a cleaning rod down the muzzle, it took a firm push on the rod to dislodge the round confirming the factory load is in the lands in my barrel.

    Since I'm developing this load for 300 and under, I'm considering finding a lower and more accurate node. Maybe somewhere around 38 or 39 grains. Any comments on where to start or where that node might be?

    26 inch, 10 twist Shilen, 205M's, Varget, Hornaday match brass.

    The gold box stuff has issues going in a match chamber. Never had a problem with the white and blue box. Have no experience with the new packaging. I only buy to shoot as reference and for testing. Neck tension is too high for bug holes.

    Interestingly enough, some people credit the accuracy of the FGMM to the soft brass and light neck tension.

    It is very accurate. I like to say if your 308 wont shoot it inside an inch there is something wrong with your gun. I started testing different neck tensions, 175SMK's sorted by bto and VV n540 and got my 10 twst Brux bbl shooting bug holes at 100yds with a 339 bushing.

    RL15 & Varget both worked for me, seemed to be interchangeable. 1 /11.25 twist (Shilen Match 24" bbl), bolt. no chrono.
