You went after a poorly hit animal way too soon
Probably so, the impending rain put a rush on things.
No luck yet, did find one more blood spot, gonna head back with a dog soon.
Rain changes NOTHING. NOTHING. You'll learn, hopefully not the hard way.
FWIW, which will help you, waiting only runs one risk, that of a varmint finding your deer.
I had one jump the string many years ago, gut hit, she walked out about 80 yards away, laid down in an open field under a single mesquite tree. She was alive 3 hours later at dark.. Left her. Thunderstorms were coming with a front but it was to early to even take a dog... We left her. About 10 hours after the shot and about 3 inches of hard rain later, she was dead, still laying there..
We've also jumped a couple of bigger body bucks that were double lung hits... 3 hours later.... we give them time, they aren't going anywhere if they are dead... thats the point you need to get.
Luckily those bucks ahd bedded, and clotted up, and getting them up, they didn't make another 50 yards before breaking loose and bleeding out the rest of the way.
With a bow, the LAST thing you want do be is in a hurry. EVER IMHO.
Dog wise our dog found a rifle wounded buck last year, after 5 inches of rain that lasted 4 hours.... a dog can find the deer if you have one, don't rush....
Patience is really hard... We've been lucky that almost every bad situation we found ourselves in we backed off and gave it time, when giving it time, its always worked just fine. Unless the deer is not mortally wounded.
I"d think half penetration said it hit the other shoulder and bounced back also IMHO.
And Im not bragging, but over 100 animals with a bow, IE big game, deer, pigs and the like, and in on tracking/finding probably another 300-400 over the years... BTDT, time is always your friend.
