Indeed 71.8 it is.

I have added back 8fps to your speed to get 2 635fps adjusted for the muzzle velocity. I then recalibrated the burn rate which has moved from 0.4100 to 0.4056. And the load of 71.8gr is smack bang on the correct barrel time.

Cant believe how well behaved this H4831SC is!

A little more data about your load according to QL.



Cheers
