Starting to work up Hunting loads for the 3 .308s. A Savage Axis, Marlin 7X, and Rossi Wizzard.
Step 1. Measure with an O.A. L. gauge and see what the length is from the bolt face to the lands, results, Took 5 readings and then redid them 5 more times and took the average.
Wizzard: 2.835" Had a deviation of .003 over 10 readings
Marlin: 2.805" Had a deviation of .004 over 10 readings
Savage: 2.801" Had a deviation of .005 over 10 readings
Seems the Wizzard is a LOT longer than the others. Will load some test rounds that are full length sized, shoot in each and then keep brass sorted and reload for Fire Formed Brass for each using the Collet neck die and Dead length seating die. Will start over with the most promising for each. Have two bullets, Sierra 150 gr. SP, FB, and Sierra 150 gr SPBT. For the yardage we shoot (under 300 yards) the FBs are the best. Will Start at .002 off the lands and go .001 up and down and see what happens. Will start with H3031 and Federal BR primers with Remington brass. Will load em up today and MAYBE get some down range from 75 yards. At 75 yds the trajectory is within .2" at 50 and 100 with the .308. That of course will be verified before season starts with the worked up loads.
