Several years back they started this with deer hunting. Like a bass tournament. Land owners would allow a hunter to hunt on his property and whoever got the biggest buck won. I am really glad that didn't take off. Not quite the same but a competition with prize money involved.
You will eventually have to full length size if you reload the cases several times. More than you asked but forester fl sizer is a really good design and the Redding competition shell holders enable you to jam the shell holder against the bottom of the sizing die making die set up a great deal...
I'm sorry this happened to you. I would smell the meat. Don't know how long it was without refrigeration. Is the meat colder than 52 degrees? I don't think refereeing meat hurts it. I freeze my venison that I'm going to grind until I've gotten several deer and grind all together.
Put a case in the press and run the ram to its highest point and screw the seater down until you feel the crimping feature touch the case mouth and then back the seater die out a little bit.
I put a leupold 1x4 pig scope on mine and shot off sand bags to see how well it shot. With cci standard velocity I was really impressed. Quarter inch groups at 25 yards.
