I have an AAC 16" and a Noveske 8.2". Both have been great. Neither are cheap.
As for Radical, I have a 6.5 Grendel and a 458 from them. The 6.5 runs awesome, the 458 runs horrible and I wish I had gone with a different brand.
In my opinion, unless you are trying to go subsonic there are better options for shooting pigs. 300 blackout will do it for shorter distances. For supersonic and possibly longer ranges, I think the 6.8 SPC or the 6.5 Grendel are better choices. If I am going pig hunting and shooting supersonic rounds, I'll take the 6.5 every time. Some will say 6.5 is expensive. I just bought 6 boxes of Hornady Black ELD Match for under $16 per box shipped from Brownells.
It is far more important to be able to hit the target than it is to haggle over who makes a weapon or who pulls a trigger.
