This morning the temperature was 26. Elevation was 4900'. There was zero breeze in the beginning. The first 6 shots were loaded and fired without haste. Wondering if the warm barrel was resulting in slower muzzle speeds, the seventh shot wasn't taken until the barrel felt cold. The eighth shot wasn't taken until the barrel felt cold, but the air started to move some. The ninth shot was hurried so to beat the building breeze. The tenth shot was taken after the barrel was cold, but by then there was a noticeable breeze.
This rifle is the only one that can shoot 400 yard. The cds dial was turned almost a full revolution. The last time out a dimple was punched at what appeared to be 375 yard mark. There were 5 clicks between the 350 yard mark, and the dimple. So, 5 clicks were made beyond the dimple thinking this would be zero for 400 yard. There is only 2 click from this 400 yard mark to the 'stop'. It appear this scope and rifle max range is 410 yard or so. The rifle is a 45 caliber Knight Disc Elite topped with a Leupold ultra-light 3-9 power scope, that has a wide duplex reticle, and a cds dial. The load was 200g SST, 120g BH209, smooth blue sabot, and W209 primer. The cds dial was engraved for the 200g SST at a muzzle velocity of 2270 fps.
Ron, that's awesome. Shots 1 and 2 are all you need anyway and looks like you're spot on.

Do you walk out there to check the target after each shot?

Impressive stuff there. 400yds is a LOOOONNNNNGGGG way. Bronko is right...shot #1 is what really counts. Good shooting man, awesome. Those CDS dials sure are something, I'll say. I personally at this time have no use for one...but you've proven they are worth it for long range use.
How far off was your velocity?
(oh, and once you peel the target from your stand...that's an amazing 400yd group! )
part of it is the MV dropping as the barrel heats up. for the POI to change 2 moa your having serious MV swings. alot of it is your scope, its set to be parralax free at 100 yards and your shooting 400, no way can you keep a consistant POA with that scope at that range.
