44 mag for deer

So I finally got an opportunity to take a shot on a doe with my 44 magnum. 22 yards using a 6.5 in model 629 and a 240 Gr factory hornady xtp. I had a great hit and good blood for 30 yards and then it went to specs. Tracked it for 200 yards following specs of blood then lost it. Any thoughts or tips? I’m new to handgun hunting and would appreciate some help.
