Thread: Fast twist 22-250 Load advice

For the 77gr TMK:

2208 or 2206H are looking like the best options. I would try them in that order.
2209 & 2213 are a little too slow.
BM2 is definitely too fast and results in a low case fill (<80%).

Because its a 21" barrel you're losing a bit of speed, ~100fps. But the 2208 is still almost all burnt (>99%). It will be loud!

The QL model has 34gr 2208 at just below max pressure, 96% case fill ratio. So start around 32gr.
