I appreciate any help, as I'm totally surprised, given the circumstances, that this deer didn't just drop in her tracks. I look forward to hearing what anyone thinks.

I think that sometimes they just don't fall. Heck, I shot a runt buck a few years ago through the ribs this a load of 000 buck, and he ran about fifty-sixty yards. And last year I shot a beautiful 8-pointer through the heart with a 240 .44 XTP bullet out of muzzleloader - he ran 75 yards. Go figure. After several years of using a muzzleloader, I got a Marlin 336 mid-way through this season. My results thus far:
Deer 1 - young buck - shot him head-on. Ran off apparently unhurt; found dark blood, trail petered out, looked two hours. Found two days later, in one direction I didn't go. Bullet entered chest, excited ham. Bad shot.
Deer 2 - 3-pt buck, broadside at about 40-50 yards; deer took off & ran a loop about 40-50 yards and fell. Lung and heart both hit. Good shot & performance.
Deer 3 - Buck - just a few yards from tree at dusk, steep downward angle. Bullet went down through shoulder, just missing spine, got the front front of a lung. Deer dropped straight down, kicked a minute, but never got up. Good.
Deer 4 - nice-sized doe at dusk, hit just behind shoulder. She dropped straight down, hardly kicked. Bang/flop, dead right there. Perfect double-lung, just above heart. That was the first time I'd used the 170gr load (others were 150gr corlokt). I think I like the 170, though I don't know that it makes a diff.
Deer 5, last of season, this morning - an even bigger doe - I flubbed the shot and hit a little too far aft, hitting last rib. She ran a few yards into thick stuff and lay down - I levered in another round and shot her in the neck right below head.
Where you hit them matters vastly more than what you hit them with, and sometimes they just run off. I think if you want them to fall RIGHT NOW every time, you need to very carefully hit spine or head or high shoulder. I thought I liked I the high shoulder, but now go for lungs - it's a bigger target, they won't go far, and you don't pulverize any much meat. If they're broadside at an angle, aim for the off shoulder. I aim for about 1/3 to 1/2 way up from bottom of chest.
I really, really like this Marlin; 30-30 is a good cartridge.
