I think it will be very interesting to see how the extreme spreads compare. Sabotless did better than sabots this time. I would imagine a closed 209 ignition might be even better.

I hope you get a chance to try some BH209 with the Mountaineer too. Its done surprisingly well in the 45s sabotless, especially with heavier bullets. Now, i wish i had sent you more of the Rem 385gr CLHPs.
