7mm WSM 24" barrel
139gr Hornady SST
B.C. 0.486
Fed 215M primer
71gr RL-19
3300 fps
1000ft above sea level
70 degree's.

This info is out of the Hornady(Sixth Edition) manual,now what I am looking for is the velocity(@ the muzzle) out of a 30" 1-9 twist barrel and the drop at 1000yrds from a 100yrd zero.

Thanks a bunch SMACK....I want to use this load for Groundhogs,I'm going to use the Berger 180 VLD's for paper and steel.....

Smack......First off, according to Quickload, that load exceeds MAP. It shows a pressure of 71,994PSi when the max average for SAAMI is 64,542. That said...here's the data from Quickload, and Quicktarget. Muzzle velocity from a 30" barrel is 3,531fps. (QL doesn't differentiate for twist rate) Zeroed at 100, with your atmosphere data, it shows a drop at 1,000 yards of 58.3".
Max with QL is 68.5 Velocity 3419.....drop at 1,000= 61.2" Good luck, and be careful.

Paging Mr. SMACK... here you go..

.. the Muzzle Velocity you wanted is a bit optimistic I think, BUT I used the 3300fps anyway.
