I have found, personally, that any deer that has me spotted is a "no shot" situation. Even if I got the shot off somehow, the wired up deer is GOING TO move and I have no idea how much before the arrow connects.
In the senario above, I wouldn't have even considered it.
That said, if hunting from the ground and under 15 yards with a deer that isn't acting hinky I"ll take the brisket shot in a heartbeat.
The other guys above have it right. If you have faith in the penetrating capabilities of your set up and your ability to make a decent shot, then take it, BUT if your mind is saying "oh man, I don't know about this shot".....don't!!!
Some may laugh but that single negative thought will knot up the muscles, mess with your concentration and make a good shot danged hard to complete. Just a bad idea, IMHO.
For me, the HARD rear angle shot, although I know it's deadly as heck, is one I flat wont take unless I'm RIGHT on top of them. I mean like 7-8 yards at eye level! LOL!
In my mind that big ham covering a large part of what I can see just messes with my head too much. I DONT want to put an arrow into the ham even though I think I'd get "enough" penetration.
A punctured ham, guts busted and thinking of all that "stuff" I have to get through on a bad shot to get to the lungs just messes with my confidence and I don't shoot.
For me and my set up? I'd take ANY angle on a front end shot over the hard angle rearward shot, but again, that is just me.
Every since my second deer decades ago that didn't cause of the crappy four replaceble blade head I decided to use, I've never got less than penetration to the feathers. That much penetration anywhere in the front quarter of the body is one dead deer and a short blood trail for me.
One STRAIGHT at me wouldn't be my preference of the front end and I'd wait a bit for the angled shot in front of a shoulder heading behind the other shoulder.
Thinking all my shots out, I want the head to come OUT the other side and have an exit wound just to be safe, for an increased blood trail, if one is needed but 90 percent of the deer I have shot go down in sight. Knock on wood!!
BEWARE of the deer that has you pegged! Them suckers are QUICK and just not worth the risk to me.
God bless, and safe hunting gang. OCT 1 is sneaking up on me fast!
