Here's how I judge a deer.If the outside of the mainbeams are touching the outside of the ears it's close to 16" inside spread.If the inside of the mainbeams are touching the outside of the ears it's close to 18"inside spread.The average mass of a deer is 30" with all the measurements added together.Average mainbeams are 23"to 25".If you add these so called constants you add 18"+30"+50"=98"or round it up to 100"then just look and guess the tine lengths.That should get you close.I learned that from a guide and a taxidermist.

If you are required to shoot deer that score over a minimum, you better forget spread.   As a BTR scorer and someone who has seen over 200 bucks in the woods and brush of Texas over 130" and measured dozens if not hundreds more, you better believe that spread has very little affect on score.

As far as tines, to get deer consistently that score 150"+, you are gonna need  great tine length on the G2's and G3's (average for all 4 tines in the 9"-11" range) and the G4's on average need to be pretty good.   (4-6"

Browtines are also important.   The difference between 2" brows and 6" brows in 8 total inches, which will go a long ways.

Mass is the second most important measurement and may be the MOST important.  I've measured bucks with average to below average tine length but great mass that was 160".   I measured one a few weeks ago for a guy in Huntsville, AL that didn't have a tine over 8 4/8" long (11 scorable points total) yet he was 161" composite mainly because of his mass.   I have a friend here in Florence, AL with a deer with 10 scorable points (mainframe 8pt with two 1 1/8" kickers) that scores 152".   Nothing special about the tines, beams or spread (16" wide) but he has somewhere around 35" of mass.   That's over 4" per measurement and his 2nd and 3rd measurements are better than the bases.

I've seen deer in the upper 130's shot that were less than 12" wide.

I've seen deer 22" inside only go in the lower 130's.

The difference in 15" and 20" of spread is....5".  That is it.    The difference in good mass and average mass could be 10-15", along with tines.

THERE ARE GONNA BE EXCEPTIONS TO EVERY RULE.    And REMEMBER, an 8pt that scores 130 will be lots more impressive than a 10pt that scores the same.  Shoot the frame, not points.  Unless you just want a deer with lots of points or real wide.

I look at frame and mass.  THe heavier, the better.   Tall tines will stick out like a sore thumb.   Great mass will also.   It may worry you now but I promise, when a 150" steps out, you'll know it.

Just use the OH S#$t rule.  If you say OH S^$t when you see him, you better shoot.    You have to take a second look, he's probably not worth it.
