To that end my extended family of legal CCW posessors who are in volunteer fire and other emergency services are gearing up. So out from the back of the safes come the FNFALs, the M-14s and other major caliber weapons by the over 40 crowd , under advice from "ya better call Gordon" as the new tool against foriegn invasion. Seems the modis operendi of the cartel growers is to put four heavily armed enforcers in their 4x4 SUVs and approach your properties and get as close as they can to dwellings before disembarking into concealed positions. They have done so a couple times but use of direct UHF contact to Sheriffs have resulted inapprehension before the firefight starts ! However for such tactics on a sconce , the 7.62 in a bipod equipped FNFAL, or M14 , AR 10 7.62x51 seems to be optimum from an alerted dwelling which should have monitored cameras or guard on duty. Yes it IS that bad currently ! Yes and a Garand with a can of M1 or M2 AP on strippers would work too . 5.56 doesn't do so great on SUVs in my experience, where as 7.62x51 (or 7.62x54R) does the job. Just saying. Obviously for fire and maneuver fighting 5.56 or 7.62x39 is just fine. I'm trying to help here and don't want to argue about what I am currently very concerned about on a daily basis.
