After doing some load development I thought I would post an update.

I am using 215 gn Woodleigh RNSN projectiles which have an recommended impact velocity of between 1800 and 2200 fps.
After a bit of testing I settled for a load of RL 15 which gave a velocity over the chronograph of just over 2200 fps with mild pressure.

Then it was out for a few shots and here is the results. Target at 50 metres. The rifle is a delight to shoot and I am happy with the results.
