Greetings GWH and7mmsaum,
Thanks to you both. GWH I was looking at single loading for the 162 AMax projectiles as they need a LOA of 74mm or so to get close to the rifling. this is a very long projectile so chews up a lot of powder space if loaded to mag length. Either the 145 grain Speer or 150 grain Remington would be loaded to mag length. 7mmsaum my Sendero is the early model and I have tried 66 grains of AR2217 which gave around 2,900 fps and shot low and left compared to the Remington. Will work up from there.
Regards Grandpamac.
