690 is standard AP. Off the top of my head If I remember right the BC is around .670
I have had VERY good accuracy out of it even with pulled and resized projo's. Summit has had lots of good and bad reviews but you will need to chrono them to get good results out of it.

I have never chronoed 50 before any dangers there? I have the plastic wind screens. How far should I place it away from the muzzle? CED is the manufacture of the chrono. Thanks
depends on how accurate you are. No I am not joking. You need to look down the bore not the scope, and get AT LEAST 10 feet, better is 20 feet. Should be in the 2,650 to 2,750 range.
Well I was worried about the shock wave and the plastic screens.I have a laser the fits in the chamber. What I though about doing was hang a piece of paper off the last screen and make sure the dot is perfect. Lock every thing down and go from there.
Mechanic is spot on .670 B.C. Chrono or check drop at KD for velocity per lot in hand...
Summit has moved in there brand new building with AUTOMATED equipment and should see some quality Hi production come from there facility if they keep testing there quality with field tests as they go..
It is not magic to make good .50 ammo. It is just very labor intensive to prep cases. There is a lot of good powder out there now like Vit, reloader 50, H50BMG, etc. and an excellent selection of bullets for every conceivable shooting type. Some of the most accurate stuff I have shot through my Windrunner has been Military 690 pulled and resized. Good bullets.
