It's been a long time since I shot any deer with a .357 (have hunted with a .44 since about the Lincoln Administration) and I think I used the Speer or Hornady 125gr. JHP in handloads. But I would echo "
Inspector's" comments re: loads. In factory ammo I think I would favor the 158gr. Federal "Fusion" as long as it was consistant in my gun.
Deer trails often get used only at particular seasons - usually depending on food sources and the amount of screening cover, etc. So anytime you trail-watch it pays to make sure it is being used
currently.
In flat farm country (like say east of Marion) the presence of water (and cover by it) usually influences deer movement a lot. During hunting seasons the deer will get shuttled up and down a stream from one farm to the next and to another and back again as dictated by where the hunters are. They'll simply head for streamside cover that the hunters stop at because they don't have permission to hunt there. Since cover is often at a premium they get in the habit of running off only as far as they have to to stop the immediate pursuit.
If you're in an area with larger tracts of woods - maybe southern Indiana - it will pay to start looking for scrapes and rubs because both does and bucks will frequent such areas. If you find a line of scrapes - try to pick a stand
above the line, even if only a little bit. And stay away from the line as much as possible because you don't want it saturated with your scent. Remember a deer following a line of scrapes will almost always be following it
into the wind and that is the tip off about how to set up and which direction to look. Keep in mind the "prevailing" wind
may be uphill in the mornings and downhill late in the day.
More than you asked for but I hope it helps. Taking deer with a handgun is a grand thrill even after years of doing it.
Good Luck !
