    Coop, have you added in the gas port size and position for the grendel? Makes a difference. Have you calibrated the powder model...

    I like 90 to 100% case fill. And 95 to 100% burn. Some cases and bullet that's not possible or realistic. 🎅

    Just an FYI 100% case fill does not mean 100% of the space inside of the case has powder. 100% case fill means from the bottom of the...

    I guess that's why we are all different lol. I think opposite to this. I'm more worried about that dark close shot that happens out of...

    Mine are usually set at 7-8ish. Depends on the lighting conditions. I can see the reticle at lower powers but it's easier to pick up...

    At 800+ yards? I'd love to see someone hit a 2MOA target at 800yd in a 30mph wind with a cold bore shot. That's some world class...

    Yes, its free and mostly based on Europe data and powders. If I plug in like 30-06 using reloader powder its real close. But off using...

    GRT is free, isn't it? An extremely quick and dirty on QuickLoad comes up with that exact FPS on a 6.5 Grendel+123 ELDM and indicates...

    Per my previous response, I prefer >90%, so most strive towards a 100% fill ratio and sometimes beyond.

    What about your burnt rate % based on barrel length, powder burn rate? You always strive for 100% or in some cases is 90% burnt good?

    What do you consider optimum for case fill% and burn%? What do you consider the low side limits?
