I’d have to go check my dad’s notes but we ran the 77’s and Staball 6.5 up to 3200 or so with a 16” barrel if I remember right. His gun doesn’t like to be pushed hard so it’s around 3050 now.

After some pressure testing, I loaded 80ELDMs at Hornady's maximum load and 77TMKs at Sierra's Maximum load using Staball 6.5. Both Hornady and Sierra list these loads at 3400 fps with a 24" barrel. I realized this is a new 18" barrel, but I only achieved a high of 2909 fps with Hornady's load and 3006 fps with Sierra's. There are no signs of pressure, but I'm hesitant to continue with this powder. Has anyone ever tried Staball 6.5? If so, what were your results?

I didn't have great speeds/accuracy with Staball 6.5. N560 has been a great powder for me with 80 ELDMs and a 17" barrel.

85.5 Bergers shoot great for me with 40.5g of SB6.5. I'm headed out tomorrow to try some 77TMK's and 80ELDX's with SB.

What speeds are you getting with N560?

I'm getting 3125 at 44gr N560 (Hornady book max) out of my 17" barrel with no pressure signs.

The gun shoots the factory hornady ammo at 2950.
