Take a look through this thread: "Sleuthing the Federal Gold Medal Match load".
Apparently IMR4064 is the current powder used in FGMM 168/175 loads - it will shoot just fine.

I had some ammo loaded with 41.5gr of 4064 topped with 168smk's. Shot .75moa @ 100yds out of a 700 AAC-SD. Gold standard powder for 308 imo.
4064 is also what the military went to for their M118LR loads.
I use 43.5 out of a 24" 1/12 Schneider M40 barrel and get about 2740. it's definitely a good powder.

Win brass
175 SMK
2.80 OAL
44.2 4064
Always under .75moa, often around .5moa in my factory Rem 700 5R 20"
Been very happy with this combo.

The new mk118 mod 0 is 41.7-41.8gn 4064 w/ 175smk. I had much better luck with the 168smk outa my 26" at 41.7gn 4064.

Well, that depends on how much temp variation is too much for you.
The first charts from Hodgon when Varget came out showed IMR 4064 with about half the velocity variation over the interval tested (0°-90°F???) of Win-748, which was still near-infinity more than the almost-zero variation with Varget. Specifically in .308 and using the 168 SMK. Now since your 20° F shots with Varget will STILL hit lower at 800 yards than they do at 100°F because of the different air density, I decided that sticking with a US-made powder and not being tied to cargo ship schedules was more important than getting near-identical velocities at all temperatures.
Then the powder and primer shortage hit and I could find 4064 twice as easily as Varget.
Then Obummer got re-elected and the next shortage hit...and both became Unobtanium for a while. A long while.
Not sure what I'm gonna do next. If I can get more bullets soon, I'll look at Varget again, but only because there was a promising load a while back and the 4064 loads seem to have sped up past my accuracy node...and mostly because here, Varget is showing up a tiny bit more often than 4064...
Ive recently been working 4064 as well. Prior i was working ball powders such as 2000mr and Win 748 and Benchmark. Had a few retired F class members at my lgs recomend 4064 so i bought 2#. The good is that its an awesome conaistant powder and lesser priced compared to newer powder hybreds. Also readily available near me. The bad is 4064 is a long stick powder that does not meter well so you have to patiently trickle. My pet recipie is 168 smks , .020 jump, and about 42.4 gr. 4064. Still my 2000mr is my best performing powder but im not finished testing 4064 so its still work in progress.
I get 2740 fps out of my 24" tube running 43.4gr of IMR 4064 under 175 smk's in Hornady match brass with Fed 210 primers. Will shoot sub .5moa so I'd call it a winning combination.
Go for it Bro! That's one of the top powders to produce a real shooter there! " IMR4895 runs less pressure with the same velocity." If you ever get the chance I would pick some of that up to chrono. along with some BL-C(2). But, I tell you what though, I'm hearing super awesome things about CFE223!! Guys that know a lot more than me and shoot for a living have been using it in 308Win. in place of Varget with great results. They say their not going back to Varget in less they have to.
My goal is to not be affected by a specific brand powder shortage. I want to be able to buy a # off the shelf of whatever medium burn my LGS has in stock, go to my Excel database, get the numbers, dump the loads and shoot precise and consistant and NOT be limited to a single "goto powder". Right now I can load up 2000MR, Benchmark, Win 748 and all will produce around .9" groupings at 200 meters so I'm content with my powder "diversity"
