New TMK announced

If you don’t mind, I was taught that basically those would both be +/- 6 mph loads if speed was in the 2850 range. I believe I noticed a prior similar post on a higher mph then the g1 bc.

Could you explain for me?

Plug into an app set wind angle to 90 degrees and increase wind speed until you see a shift of 0.1 per 100 yards = your wind # for that load.

This is the 107 (guessed based on a 1.370 bullet length) at my dA, w a 8mph 90 degree wind

If I remember correctly, the "first digit of g1 BC = wind bracket" heuristic is valid at lower density altitudes than people might be hunting/shooting in some states. I'm often hunting at 8k and above, so something that would be a 6mph gun hunting pronghorn in Eastern CO is a 9mph gun hunting elk.

At similar velocity they are going to be darn near the same.

.292 to .305 BC is barely any change. No way you’re going from an 8-10mph rifle without some serious velocity involved.

Gun number isn’t a one size fits all solution either, yea you can be close just guessing off the g1, but it’s not hard to put in a solver and figure it out at your velocity and DA.
