Thanks for the info Bob. I am familiar with the Encore. I own one, but I don't really care for it. I have a bunch of Rem 700 rifles and a custom 700 ML. Just looking for a new toy to play with.
As for the powder requirement, the 10ML and the 10ML-II will handle 50 gr of smokeless, but the accuracy suffers and there is so much blowby on the sabot, the velocity is gone. The sabot acts like a pressure valve. When the pressure is too high the sabot gives way and the blow by occurs. I have heard they do perform nicely with MMP magnum sabots and a 45 caliber magnum bullet.
