Exbal and the G'S

jeff not sure this will help you but I was using a stepped Bc with the 300 smks. I know I was using .84 from the muzzle at 3200fps and dropped to .8? at around 2700 fps. I cannot recall exactly because I switched bullets and have not played with them in a long while.

Thanks i'm going to try and start out fresh this weekend just like its a new set up and go from there. But the .800 is what i remember being used for 2800-2900 and thats what i;ve been using out to 1000 but after that its gotten a little krazy on me.
Thanks again

If your rounds are striking over what exbal is saying and only using one BC then this could be the problem. This is what Sierra has on their site and what I've used, but only out to 1060yards.

.768 @ 2300 fps and above
.760 between 2300 and 1800 fps
.750 @ 1800 fps and below

I have only ran these between 2740-2870fps out of my Edge. I'm sure that it could change for the guys running faster velocities, but .8 sounds a little optomistic for me.

I find myself having to retract this statement. I had to upgrade my program from version 9.6 to the newest version 10 due to a gliche in 9.6. Just did this yesterday.

The new version 10 does support G7 BC's. They have to be supplied by the bullet manufacturer, but it does support them.

The PPC version still does not support G7 BC's.

Good point, I should have mentioned that version 10 is the PC or home computer variety.

I am not an expert on this, but I called mr perry to discuss a few things with him. one of the things he told me was: when you are entering your bc, if you go to program options and then find bc's and click on the bullet you are using, it will use all three bc's. if you enter it yourself it is only using the one bc.
