I picked up a bunch of TAA headstamped military brass and loaded up 30rnds to test out going from 43.0 gr up to 44.0 gr in 0.2gr increments.  Went with this on all loads with the charge listed being the highest charge I used:

Trimmed to 2.005
Fed Match primers
44.0gr Varget
175gr SMK's
2.820 COAL

All I've seen in manuals about charges is stay 1gr below max charge with mil brass due to decreased case capacity/increased pressures.  Anyone shooting a similar load with mil brass and did you get any pressure signs?

I have had LC cases show overpressure sign well below (2-3gr) max. I stopped using it in my long range set up. I run it through the 1919 without concern.

it should be 10%  , so 4grns lower than max... in my AR10 my LC shows signs at 43.5 of varget with a 175. Right now my favorite load is 41.5 of Varget but YMMV   what gun are you reloading for?

It's for a Sako TRG-22.

if its a bolt gun and I was using LC i would start about 4grn below the start load and work my way up till you see the signs. do a ladder in .3 grn increments , that how i found my limits.

Pulled the bullets and tomorrow I'll get at working up some lighter loads.  When comparing case capacity to Winchester and Remington against the TAA there wasn't much difference, with Win having the most, Rem second, and the TAA just barely less than the Remington.  No use taking chances though.  With LC and 41.5gr Varget using 175 SMK's what kind of velocities are you getting?

no chrono for me , but I get sub moa and its gentle on the brass for an AR10 with 41.5 , plus I'm only shooting to 300 yards. I urge you to read this entire article , very good info and load data  .

I agree with working up your load.  Especially if you are near published max.

My load with LC brass and the 175grn SMK is 43.8 grains of Varget.  2,582 fps.   No signs of pressure.  YMMV

why Varget so popular ? 4895 and others have worked well in 308 for years.

4895 works just as good and I use it as well.  Both meter like shit in a powder measure though...

I use once fired LC through my M1A and remington 700. Through both of these rilfles using 168gr Sierra Match Kings and Vihta N135 I get 2650-2700fps with a 41.2gr charge. In commercial WW and RP cases I need powder charges of 44.4 and 44.2 respectively to get the same velocity.  If it were me and I had 44grs of varget under 175gr SMK's in military cases I would pull the bullets and recharge the cases with about 3 grains less.
