Reduced .308 Winchester Loads

Last year I tried out a couple batches of "The Load," in my Ruger Gunsite Scout Rifle in .308 Winchester.  The first patch was 13 grains of Alliant Red Dot under a 170 grain cast bullet, although I forget exact which one. Accuracy of that was abysmal, on the order of 4" or more at ~50 yards. The bullets were originally sized .311 and had been purchased by my dad for use in Mosin-Nagants. I sized them down to .308 for use in the Ruger. I may have gone a little too far. Afterwards, used a chucking reamer to to open the Lee sizing die up to .309 in my lathe, but I have not yet tried it out. It's one of the many items on my round tuit list.

The second batch was again 13 grains of Red Dot, but this time I loaded the cases with 152 grain FMJ flat base .30 caliber M2 projectiles. Groups were more like ~2" from prone, with the factory irons.

Recoil of "The Load" in the GSR feels like you're shooting an M1 Carbine.

Today, I ran across this article, linked by Brownell's on their FaceBook page: Reduced 308 Winchester Loads with Trail Boss. This looks pretty interesting, any may be something to try.
