Was out doing some load development this morning, and was really concentrating on trying to have the same point of aim and cheek weld. I'm using a sightron 10-50x-60, shooting at 300 yards on the 50x magnification setting. So my question to you guys, other than just straight repetition to acquire great site picture are there any tricks or devices you use to help keep the same p.o.a. and cheek weld. The gun is a tikka tac in .300 win mag. And the cheek piece is adjusted to the proper height.
