efw,

Congratulations on the wheel gun deer!
That 300 gr is a tad heavy for expansion on deer unless you hit some big bone. Never the less, it worked very well.

I shot this doe last year with my S&W 629 Classic loaded with Nosler 240 gr JHP and 23.5 grs H110. She quartered away at 65 yds and I hit her in the back of the rib cage. The bullet exited behind the off shoulder leaving an exit wound the size of a quarter.
