I have a #22 from cableas and I can not count how may deer and elk I've run through it. The trick to doing to grinds is to first do the finer plate, then the course plate second..... an old time butcher told me that.
Do not make wolf sounds while elk hunting, you will just make the elk leave the area. You might have wolves come in while you are bulging or making cow calls. If wolves start howling in your drainage, your elk hunt just became a wolf hunt.
Deckers are more versatile and stronger. You can use them with mantie s boxes, panniers or just tie the quarters on. Hey 33 feet of a poly blend rope, 5/8 inch for sling ropes.
You need to train him is a comfortable environment. Start with a blood soaked mantie put big rocks on each corner so it will not move, and put his grain on it and move up from that.....
I built one 20 years ago. I milled the bars from a cottonwood log with a chainsaw then shaped them w a belt sander. The hardest page
Rt was finding the metal D rings that hold the bars together. I called saddle makers and found one that would sell me just the rings.
Good luck.
