LOAD DEVELOPMENT FOR .308 WINCHESTER

[avidflyer]

Yes sir I do, over 3000fps actually, as do the rest of the Palma/ US National Team members. 30" barrels. not 26"

ran 155’s with 46.8 of varget for years...2975-3000 fps very common

2cents ! I have shoot Palma for a few to many years.
I have shoot every 155 gr. bullet made.
barrels 30" to 32" 1-13 now 1-12 .
Brass Win. Lupua and new Peterson .
Powder Varget and IMR 4320.
Primers Fed. 210m , Wolf and BR-2

Having said all that Varget is Lot by Lot not equal .
The old standard Velocity for a 30' Barrel was 2984
The new average is 3014 + or - with 32" barrel
I know people who run even Hotter ??

I have had Varget with 45.5 grs to 46.5 grs. that gave the same Velocity ?

Sierra 2156 Plama Bullets are very Good , you can jump them from .020 to .040 off with no trouble.
If ever have a mind to try Berger ? 155 HB at .020 off shoot 1 min. flatter at 1000 one 2156 in my Rifle.

Best of Luck

Berger 155.5 are very good also

Tnx for the replies. Been working a lot and no time to shoot. I have laodedup some rounds to see if I can find the Velocity Node. Then I will adjust powder hoping to refine it. After that I will play with the seating depth. I do have the tools picked up over time to allow me to find the lands.

Won't hurt to know your seating depth to the lands but the SMK doesn't mind a jump.. the new TMK does not like it as much...

As one of a few who developed loads for Sierra's first 155 Palma bullet, we settled for 45.3 grains of IMR4895. Shot about half MOA in a few dozen rifles at 600 yards.

Soon learned 46.0 grains of Varget shot as well in as many rifles.

Both loads had bullets gently jammed into the rifling with SAAMI spec chambers with a little less freebore.
