+1 on that!I really hope you plan on using a suppressor or ear pro because if you've never fired a 30 caliber rifle indoors,I suggest you try it before deciding on one for home defense.Also barrel length matters,I have a 16 inch tube on a PTR91K and I promise you,you don't want to touch that thing off indoors at night without sunglasses and ear muffs+plugs.Not to mention the pressure wave from firing such a weapon in close quarters is quite impressive,it feels like someone suddenly hit you on the sternum,not quite take your breath hard,but it's quite distracting if your not expecting it.Hope this helps.
Agree -- IMO, definitely the L. 5.56 would be best for target shooting and varmints, since there's a tremendous variety of ammo out there. RA makes both 1/9 and 1/7 twist barrels -- 1/9 is the default, and might be better for general use and a wide variety of bullet weights. If you choose to use it to hunt deer-size game, either 7.62x39 or 6.8 would be acceptable at up to perhaps 150-200 yds -- keep your range reasonable and you should be fine. And with the XCR, of course you can have more than one caliber. That said, I'm a bolt action guy when it comes to hunting -- I use my XCR for plinking, varmints, and as a general fun gun. When my suppressed SBR comes, it will also serve and as a potential home defense weapon in a worst-case scenario, but more frequently for plugging groundhogs and armadillos without leaving the house. ;DI think the L is the way to go for the first one. It offers more versatility with ammo sizes. (as well as cheaper)
The 7.62x39 good enough for most game in N. America. :2cents:
I disagree compeletly with you. Firearms are for lethal force. If you have to shoot someone, it's because you need them to 100% STOP, meaning disrupting the central nervous system or damaging vital organs. Birds shot WILL NOT kill someone most of the time. In close quarters it will penetrate further than hunting distances, but it is not uncommon for people to be shot and not even notice. I've seen men wounded in combat that didn't notice until 30 minutes or more later, because the adrenaline kept them moving. Add the potential for heavy drug use by an intruder, and you want something that will KILL, not wound.best bet is fill with heavy bird shot that won't penitrate walls but will take hours in the ER to remove the BBs
