First of all welcome aboard.
Next thing, I know nothing abt the round you are asking abt. except that you are going to have a pile of money invested in the gun and the ammo will require you form your own brass, and even then is going to be very expencive to shoot, I`m talking over $ 1 a round. I built a .22-6mm for a long range coyote gun. I built it on a Savage action and have alittle over $ 1,000 in the gun. I have another $ 1,050 in the scope that`s on it. Your gun will be more than twist the price of mine, the scope you couls get buy for alittle less, but not much. Dies and a press will cost you another couple $ 100.
The thing that reall scares me is when you said you don`t know all of the terms. That leads me to think that you have never reloaded your own or just got started. If you don`t know what to look for as presure signs you have no business messing with wildcat as all data for them is suspect.
Befor you go with that wildcat I would recomand you just buy a .50 BMG. It will be alot cheaper, blistics will be better, there is ammo available and you should be able to find reliable loading data for it.
