congrats!!! i too dropped a big doe today.....she hit the ground like a brick also...her back collapsed then she toppled over.....i hit a bit high(guns sighted in at 50 a bit high so at 100 or so it was still climbing...) but i took the lungs and blew them to pieces...and the shock probally dropped her right there(shock sent waves to the spine im betting)..ive only had 3 out of 6 deer now go anywhere....both were with a solid shoulder hit....and one i hit monday right smack in the middle of the heart....she made it maybe 40 yards or so......but she was dead when the bullet went through the heart....running into trees ect....she wasnt alive for that last run......congrats on the big doe.....success is sweet!
