Thanks Terry,
Twist rate, free bore ?

Twist 1:9, free bore, way too much. Sent the reamer back. You need very little. Reamer says .068. If it really is, that's too much.

Impossible. Everyone knows sub-calibers are terrible in the wind. Especially at long range.

As Terry noted you don't need a lot of freebore in the 20br due to the long neck, I believe i was only running approximately .020 in my ackley improved 20br.
