I don't know a whole lot about wildcat AR cartridges. The more popular ones I know of end at 300 Blackout and start back up again at 450 Bushmaster. Are there cartridges in the mid-range, say .35-.40 or 9-10mm, that are designed for the AR-15?
I've got one of the D-Tech uppers (see my sig line). Shoots .4's. Took a deer this past week end at 279 yards. My friend that I hunt with just ordered one after seeing how mine performs. Wait is about a year..358 WSSM, I think this one was designed to get around some law regulating what cartridges can be used to hunt deer in Indiana.
Most of the guys around here that have them are reporting 2,800 fps range with 200 grain bullets. Haven't crono'd mine yetWhat kind of velocities are you getting out of your .358 WSSM? Is the .358 WSSM restricted in terms of bullet weight?
