What caliber, gun, and mods are needed for shooting commercially available slugs at 300y+?
So, if I wanted to play this extreme long range game, but just not quite head-first-down-the-rabbit-hole as some of my ExLR heroes... — what does it take?
(1) First of all: At 300y I'd like 2 to 3 MOA precision. Does that sound realistic?
(2) What calibers should I consider?
➔ taken in consideration that I would be using commercially available slugs (either airgun slugs or firearm slugs)
➔ taken in consideration that I would be willing to get a barrel for this gun (Troy Hammer is in the process of making some)
(3) What guns are easily modifiable to make the kind of power necessary to drive the slugs?
▪ I'd like my gun to be somewhat "portable" — tethering is not an option.
▪ What mods would be recommended (and no, I neither have a shop nor the gift, I'd have to send the gun someplace)?
▪ With a 700cc bottle, what kind of shotcount could I be expecting?
(4) What kind of expense am I looking at for taking the ExLR plunge?
Maybe I shouldn't be asking these questions. That rabbit hole is deep. Really deep....
