Mark fixed me up with 10 pieces of new Starline 260 brass, and 1 piece of Hornady for comparison.
I mounted a spare 20X SWFA Super Sniper rifle scope on Marks Encore. Scope height was 2.0"
I decided to start with light bullets and loaded my first 11 rounds with 42.5 grains of RL15 under a 95 grain V-Max seated about as long as I was comfortable with.
With only 11 rounds I was not expecting a lot.
I set a target up at approximately 25 yards with a 1/2" White dot for an aiming point. Adjusted the Super Snipers parallax until I had a clear target.
The First Round was way low. Up one full revolution. Second shot Up another full revolution and Right about half a revolution. I was fairly happy by the 4th shot. I had my brother watch the 200 yard Steel with his binoculars to see where I hit around the target. First round hit a little High and Right of center on the 14" X 14" steel Plate
. A little adjustment, and the Second round was just left of center.
Down to the Hi Power range to set up the Wichita Rest at that location.
I then put a couple on the 300 yard steel holding on the top edge of the plate.
I then held about 1/2 Mill over the 400 yard steel and connected on it. Down to 2 rounds left. We set up the chronograph to go through it while trying for the 600 yard steel IDPA Silhouette.
Holding 2.5 Mils over the top round One was a hit. I fired the last shot and another hit.
Velocity readings were 2865 fps and 2898 fps. Temperature was approximately 90 deg, 1200 feet altitude, and fairly high humidity. I was expecting about a 370 fps loss in listed 24" Barrel velocity when fired through the Encore Pistol. Looked more like about a 300 fps loss in velocity.
WAAAAAAY More than I expected for my first outing to get a rough zero.
I will need to work on my RCBS Full Length Sizer die a little. It is not sizing the 260 cases down enough for the Encore to snap shut.
I have some 107 SMK bullets I may try next. I will need to run by Carters and get a box of 120 Nosler BT bullets some time next week.
The Bullberry muzzle brake is a little louder than expected. I had only fired one round through a rifle scope mounted on a pistol before today. That was on the Nosler M48 Mark has been playing with. That also worked out much better than expected. You definitely can see much better through a 30mm 20X rifle scope than a 2-7 pistol scope.
More to come.
