I used the Hornady Service Rifle data for 3 loads and pulled the 4th load from the Sierra book. The bullet is the Sierra flat base 150gr Hollow Point. These are the first .308 rounds that I've put a crimp on and I got a little heavy on a couple of rounds. Definitely gonna have to watch that once I find what the 742 likes.

1) 38.8gr IMR 4895  2300 fps book/actual forgot to turn Garmin on

2) 39.9gr IMR 4895  2400 fps book/actual 2271

3) 41.1gr IMR 4895  2500 fps book/actual 2363

4) 41.7gr IMR 4895  2550 fps book/actual 2482

Gonna shoot these 4 rounds out of my Rem 700 SPS Tactical to get a baseline on velocity before we shoot any of the others from the 742. The 700 is a 20" barrel and the 742 is 22". I'm curious as to what the difference will be with 2 more inches of barrel but using gas to operate the action vs the 700.
