    Advanced Marksmanship My "Weaponized Math" now called "GRAVITY BALLISTICS". NEW Worksheet Attached.

    Maybe. Seems to me you're just not willing to explain it and you're getting frustrated.

    Advanced Marksmanship My "Weaponized Math" now called "GRAVITY BALLISTICS". NEW Worksheet Attached.

    I guess I just don't see the point of this worksheet? You walk your shots onto targets in case you don't have a ballistic app/calc. with you? Battery goes dead or something?

    Advanced Marksmanship My "Weaponized Math" now called "GRAVITY BALLISTICS". NEW Worksheet Attached.

    I'll try it in real-time this Thursday at a range that has steel out to 1,500 yards, every 50 yards and see if it matches up better. I think you have it backward with the MV? I needed LESS elevation after 800, not more. My rounds are flying FLATTER than my calculator suggests. The number in...

    Help Interpreting DOPE

    I think I figured it out. It's probably down to BC. I've been using a G7 BC of 0.312 for years and it's typically worked. This is what Hornady published when they first released the 140gr ELD-M. Their website now lists the BC as 0.326. I'm betting if TRASOL had the ability to input progressive...

    Advanced Marksmanship My "Weaponized Math" now called "GRAVITY BALLISTICS". NEW Worksheet Attached.

    It kinda works and makes sense, but not out to 1,000 yards for me. For example, this past weekend I shot at 200, 300, 425, 500, 600, 800, 900, and 1,000. And I got real-world come-ups. At 300 yards, my come-up was 1.2 MIL. If I follow this worksheet out to 1,000 it spits out 10.5 MIL. But...

    Help Interpreting DOPE

    I don't understand what you're saying. My real-world data is listed above. Ignore the calculator and DA then. Try (Actual): 200 Yards: 0.48 (0.5) 300 Yards: 1.2 (1.2) 425 Yards: 2.26 (2.3) 500 Yards: 2.97 (3) 600 Yards: 3.98 (4) 800 Yards: 6.31 (6) 900 Yards: 7.61 (7.3) 1000 Yards: 9.06 (8.8)...

    Help Interpreting DOPE

    Temperature. It gets hotter as the sun rises lol... Shooting at physically different locations and time. Cold in the morning and then as the sun rises, it's getting hotter. About 10 minutes at each firing line from 200 yards to 1,000. Not shooting in one spot at targets at different locations...

    Help Interpreting DOPE

    Just got my rifle re-barreled and I'm looking for some help interpreting my newest DOPE out to 1,000 yards. As you can see, starting at 800 yards there is a 0.3 MIL discrepancy between calculated come-up and actual that stayed consistent over every shot. I put at least 10 rounds downrange at...

    Garmin Xero C1 Pro chronograph

    I don't see any update for 3.16. The latest is 3.13 as far as I can tell.

    Garmin Xero C1 Pro chronograph

    This one's a bit better. Fits nice and snug and half the price. If you want a case for just the unit (no tripod), a GoPro travel case should work.

    Garmin Xero C1 Pro chronograph

    Zeroed rifle with new barrel today. Tested against Magnetospeed V3. Every shot was within 5-7fps of one another. Avg. at the end was within 5fps. This range has concrete walls/baffles between each shooter. But they're only as long/deep as the bench. Range was full and the Xero didn't struggle at...

    Garmin Xero accessories only

    I'm using that Amazon case too. $8. Good to go. I don't use any other accessories, just the chrono and the Garmin tripod so I don't need some huge case.

    Garmin Xero C1 Pro chronograph

    Yeah not worth the effort to me lol. Buy, wait for arrival, post ads, box 'em up, ship 'em out, pay fees, etc. Why bother for $50????

    Xero and case arrived today. Pretty dope!

    Weird. 0.7fps delta in each case? Are you sure you're not looking at the wrong session?

    Garmin Xero C1 Pro chronograph

    I got curious so I tried it. I raised/lowered muzzle velocity until it yielded one click (0.1 MIL) of elevation change at 1,000 yards for a 140gr 6.5CM ELD-M with a muzzle velocity of 2,790fps. Looks like 14fps is the threshold for me.
