Is it a safe assumption to say 42gr of 4064 with a Nosler 168 CC pill on top is a good place to start? Whats your go to load? I have 4064, RL15, H4895, 168 A Max, 168 CC, 168 ELD Match, 125 TNT etc.

Go have fun anything your M1A likes so will the 7.62 M1. Muzzle velocity will pick up with the M1 owning too the added barrel length, however the recoil impulse will be softer because the GP location is closer too the muzzle. 42.0grns of IMR-4064 in a LC like case @ 2.8-2.82 coal is a long well known accuracy load.
I have used many powders and its good too have a good load library because your pet powder may not available when you need it most, for one reason or the other. So here is what as worked well for me over the years. My load development is with all mil-spec cases. For loads that I shoot inside 600yds I use a plain old Winchester LR primers nothing special, and plain old case prep nothing exotic is done. However with Long Range loads I get a little more picky about my prep and primers but that's a different subject.
I will list the load data from the fastest powder too the slowest burning. I will tell you what has worked Ok, and what was Super in my rifles but ultimately your rifle will tell you what it likes the best.
125 Speer TnT @ 39.5grs COAL 2.70 it was Ok, but not spectacular.
168 HPBT @ 39.5grs COAL 2.80-2.82 This was the original Federal Match load. Shoots well in most rifles but 3031 isn't all that temp stable. If your on the firing line keep ammo out of direct sun light.
IMR XBR 8208.
Some guy's swear by it, It didn't work well for me in my rifles at any bullet weight. The Wife's AR/15 loves the stuff with any projo on top.
125 Speer TnT @ 41.5grs COAL 2.70 My rifles love this load as long as the distance is inside 200yds. Recoil is Ar-15 like level. If you can hold hard enough they will hold the 10-ring pretty easy.
135 SMK IMR-4895 43.5grs / H-4895 43.0grs COAL 2.75-2.77 this is a 300yd rapid X-ring killer my rifles love this load. Recoils like a Ar-15 plenty of time too clean up the sight picture.
155 Berger Hybrid IMR-4895 @ 43.5grs / H-4895 43.0 COAL 2.80 My 7.62mm M1 Garand is just laying it down and killing it with this load combo.
168 HPBT @ 41.5grs COAL 2.80-2.82 This my default loading with this powder, my rifles love this load combo its a well known much loved Match accuracy loading. If your rifle doesn't shoot it well you have a sick rifle or you plain SUX at shooting.
**** You will notice two different load levels with the 135SMK and the 155Berger Hy-brid.
IMR typically needs a little more powder too make the same amount of pressure that the H does. IMR/H-4895 are not the same powder there very close the loads listed are mild for there pressure so the load data overlaps a bit. Too give a example, 41.5grs the IMR will push the same weight bullet a little slower than H will. The IMR gets a weee little bump too help it along. With the 125's and the 168's sharing the same load data IMR/H, I don't bother adjusting the load. There close enough to each other for me too live with so I load and go.
With any VV powder there pricey and sometimes availability is also a issue. I treat this powder no different than IMR-4895 same load data grn for grn. It is super clean! I didn't see any difference in accuracy between the two powders in my M1A so I went back too what was the cheaper powder. I have run a few 135SMK rounds down range with my 7.62 M1 all I can say is Holy Smokes......
168 HPBT @ 42.0grs @ 2.80-2.82 COAL Good solid load
175 HPBT @ 42.0grs @ 2.82-2.83 COAL Another well known Match accuracy loading. Many shooters have legged out using it, is a clone load of the old M118NM ammo or the current M118LR load. This is my default loading with this powder and these weight bullets. As you know IMR-4064 meter's like Lincoln Logs.
168 HPBT @ 41.0grs 2.80-2.82 COAL Sweet load!
175 HPBT @ 41.5grs 2.82-2.83 COAL Another sweet load, some say Varget is too slow too be safe in the M1A. I say BS its much closer too IMR-4064 than many are ever going too admit, and its cut shorter so its easier too meter than IMR-4064 is.
Enjoy the load data, now go have fun Phil.
