I just bought a Club Cadet 50 in using the same Kawasaki engine, love it. I use it for just residential not commercial, this will last me for the next 15 years.
.223 for Deer ? I don't know because I never have one and shoot deer with it. I would not bring a .223 for Bear , Elk and Moose, especially, bear. those bear is mean. .223 probably just scratchs Elk skin.
I would save money and buy high end components such as autrotrickler v3 or v4. Get you a good single press area419 zero press. Redding dies. And so on. Do your research before buying new components.
Buy once and cry once, then you don’t buy another one later and happy reloading and shooting.
I prefer to set zero at 100 yards on my rifle, because if you need to shoot off hand in timber in a stress time.
I would set zero at 300 yards if I go to Midwest, because someone Big game is on the other ridges, shoot across the canyon.
