I loaded practice rounds for my department sniper rifle on my Dillon to include using the powder measure. At that time the rifle was chambered 7mm/08. I was fortunate to be able to attend a LE training course put on by the training staff at the 2nd Marine Division Scout Sniper School, Camp Lejeune NC. I needed 500 rounds for the course so loaded it on my Dillon with 168 grain SMKs. I had no problems shooting accurate all the way out to 1k while in the course. The course had us shooting moving targets at 800 yards. Use your Dillon, it won't let you down.
