    Ballistictools.com has a large and small pocket gauge set for $20. I'll invest in those soon.

    OCW Help. First Reload. 175 SMK HPBT .308

    I have been looking at Lapua as well for the next purchase for working up a hunting load for Elk. But first things first. I'll use my current setup for perfecting a target load workup and then move to that.

    This will be my 2nd reload on those cases. I still have some other once fired Fed's.

    Wow, that's a 3.4% difference in pressure. I'm glad I decided to reach out for help. Lot to learn. The "calculate shot groups" option looks handy as well. I may spend some time with that also down the road.

    I set it at 100 yds. That would be something to consider for sure. I may set a target at 100yds and 200yds to test the difference.

    This is a great app, especially for being free. Thank you for sharing. It shows 4064 at 94.2% of max pressure. Would you say that QL is more reliable?

    I plan on reloading and heading back out on Monday or Tuesday. I will try the 42.0 - 42.3 as you suggested and report back. I really appreciate it. I will have to download Quickload.

    OCW Help. First Reload. 175 SMK HPBT .308

    This is my first reload(and first post) and I chose the OCW load determination to see what works. I am shooting a M40A5 with Remington 700 short action and a 25" schneider barrel(1 in 12). I loaded in increments of .3 from 40.8 to 43.5. These were the recommended min and max. The load is federal...
