130 TTSX loads for 308 win

[General RE LEE]

I've been using IMR 4320 in the 30-06 with a 130 TTSX for antelope to elk. It's my son's rifle, the bullet flat gets the job done. They don't make 4320 anymore. In load development I worked up loads with IMR 4064 and Varget as well, part of the comparison process. I chose 4320, but they all shot well. When the 4320 is gone it's business as usual, just switch to a different powder.

Checkout Accurate 4064 in your 06 with the 130 grain TTSX. I get 3225 FPS over 57.4 grains Accurate 4064 with low SD and ES numbers and sub MOA. It’s a compressed load but shoots great.

I'm using 57.5/IMR4320 in the '06 out of a 22" bbl Ruger Stainless MK77 at a bit over 3250 fps on the chronograph. IMR 4064 basically duplicates that, I checked my notes and Varget is just a bit slower on velocity at the same charge. Obviously, that's with my specific lots of powder and gun. YMMV.
