Don that's about right...I got almost 180, which strikes me as light for a mule deer with a rack like that.

I got this formula from a meat packing/processing plant on line....obviously the numbers could be conservative. There's other formula's as well but they all seem to work about the same.Keep in mind we are "estimating" here.




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
