Great info WG. Thank you!
I actually did shoot my hunting ammo through a chronograph - average of only 5. But I used the B.C. on the box and standard eye relief measurement of 1.5”.
Probably should have just left it alone and used holdover because this is definitely my confidence rig. Without the magic dial I’ve killed a bunch of white tails out to 225. But nothing approaching 500. Never even gave it a thought, really.
If I can’t hunt my way to a ‘nice’ bull at a reasonable range for me, screw it. I’ll hunt for 5 days, enjoy the Rockies in late September, and try to fill my coolers for the ride home with a satellite bull in bow range.
Thats good that you chronoed them. I've never sent in for a CDS but i'm guessing by eye relief measurement you mean scope height (scope height above bore is a standard input for ballistic solutions)? For scope height, i'd do your best to eyeball it with a ruler/tape measure or calipers to confirm actual.
In regards to BC, nosler is a little high on the published BC vs what most folks see to be actual. Applied ballistics is the big dog in this space and tests/publishes BC on a lot of bullets because manufacturers are often not very accurate. Nosler publishes a G1 BC of 0.507 for the 180 accubonds and Applied ballistics tested them at 0.482 but better yet would be to use a g7 BC as they are typically more stable across the velocity spectrum and applied ballistics has a g7 BC of 0.246 for that bullet.
The BC thing is getting into the weeds a bit with ranges inside 500 yards as the differences I mentioned above dont amount to much until a little longer ranges. But if you have a chance to get with Leupold and update inputs, I'd definitely make sure you have a good scope height above center of bore and update the BC to have things as tight as possible.
