Nothing wrong with passing up a shot. I do it 10 times more than I do taking a shot.
In defense of Texans..... I've lived and hunted in Texas all of my life. I never heard of the "Texas heart shot" until the internet allowed me to interact with folks from faraway lands. Everybody I know passes when a butt is all they have to shoot at. Seems like it should be named "Yankee heart shot" or "California heart shot" or something more descriptive of the locale of its use and origin. :D
Well another Mule Deer fell to Noslers BT. I have nothing but good things to say about them Quality bullet just use them at the recommend velocity on there web site. I'm pushing a 264 Win Mag 120 gr.BT at 3225 FPS like I said before one shot one Deer again this fall shot between 200 & 250 just a point and shoot no rangeing. I had complete passthrough on a quarting away shot about 22 inches plus penetration and still going.
the 22 cal like you said make a mess out of everything in its path
the 30 cal acubonds worked awsome in deer and elk while i have only shot out to the 100 -125 range with them
i think when they are super sonic speeds they tend to expand way to much for hunting pourpous
i guess my point is i like them in either situation exploding varmits or pile driving elk
hope to run into you out in the feild some time and we can swap stories
