Staball 6.5 as good as they say?

mtnbound,

I’m a little surprised to hear that. But obviously every barrel is different.

I’ve burnt out a 243Win & 6CM using SB6.5 almost exclusively as the propellant. (A small amount of H1000 in the 243 early on.) Great velocities and accuracy. And now working a new 6GT with very promising early results.

IME, you’ve got to step on the gas to get the best performance out of SB6.5.

42.5gr and 43gr was what I tested and I had 2716fps and 2779fps for averages but had SDs over 70fps in both.

What was your recipe?

Did one more temp test to grab data with a tighter ES/SD load. Not as amazing as my first test, but still very good numbers. Also snuck in a spicy 127 LRX load (46.0gr) that crested 3k fps but that had slightly sticky bolt on one round.

44.5gr SB 6.5 with 129gr ABLR
- 5 shots warm, 4 shots cold (light primer strike on 5th)
- Zero degrees - 2864.1 AV - 1.6 ES - 0.6 SD
- 75 degrees - 2883.6 AV - 23.5 ES - 9.5 SD

Result: 0.26 fps per degree (got 0.14 last time with bigger ES/SD)

Had a 45.0gr load as well but I called it a day due to increasing light primer strikes. I was getting hot and didn't feel like diagnosing. Have 4 shot warm data, so I'll grab the cold next time.
