Thanks boys but something here ain't computing right. jmbn says his muley was 16.5" and you guys say the antelope is 16". Now even half way decent fed mule deer fork horn is deeper chested than an antelope. I generally shoot mature large bodied mule deer bucks and I guarantee they are much bigger from the top of the shoulder to the bottom of the chest. Somebody has to be off here as there is no way that there is only 1/2" difference betwixed a muley and a speed goat. Methinks I'm going to carry my tape measure this fall and see for my-own-self what these two animals measure.
Big Sky-- The extra inches comes from the "belly" measurement. The measurement on the antelope just behind the shoulder would be about 13-14". Just thought I'd clarify. That is why S1's measurements are a little larger.
