Velocity?

I'm not sure if this is the correct place for this post so please move it if needed. I have a Mossberg 810b that I'll be hunting with this year and I didn't have a chance to chrono the load that I'll be using. Not sure if I have enough data for quick load but here goes: RP cases, Winchester magnum large rifle primers, 70.0grs H1000 powder, Sierra 170gr round nose bullets seated to a COAL of 3.300, hope that's enough but I'm not sure. I'd just like to know how far out I can hit with this before it drops 4", I have it zeroed to hit 1" high at 100yds right now and was printing clover leaves at this distance. Thanks guys.

I knew I'd leave something out 7mm Rem Mag and BC is .280 above 2500fps and .317 between 2000 and 2500. Thanks

Your best source for your inquiries regarding ballistics is a Sierra Reloading Manuel. For just about any load you choose to use, there is more information in there than you can mentally digest/retain. I've even used it as a reference for other brands of J-words.
