This is the best 308 load data I have found to date for Sierra bullets.

Download it and you will save a lot of time in load development

That's a page from the Sierra manual.

yes...we don't all have sierra manuals.

Some of the TAC velocities dont ring true, but its pretty close, the 223 data is right on from my testing with TAC and Varget.

6mmbr also has a pdf for semi rifles as well.

Some of that is mighty conservative considering they list 36.3-41.7gr of Varget for a 175gr SMK, hitting 2500fps while Hodgdon lists 42.0-45.0gr getting the same bullet to 2700fps.

And than you go the the range and the velocities are even slower than Sierra has...makes you wonder how lax the testing procedures are, or is it just archaic guesses by software?????????????????????????????????????
