SURE you are. along with .45 pistol, ammo, cleaning gear, spare mags, mag pouches, spare parts, bipod,etc, 25-30 lbs of guns and gun-gear, AND the 40+lbsof other survival gear that a lame like youwould need to last a WEEK (4 seasons) of shtf.
Naw, a .308 is probably not the ideal weapon for a wandering hobo with no gear or supplies who's looking for a place to curl up and die or get whacked by those far better prepared, better equipped, and better trained/skilled.
I currently carry a CAR-15 with a .22 unit and a .45, but if my primary was a .308, I'd carry a MkII, which is a far superior hunting weapon to a puny barrel & no-velocity, pissant M21.
Regarding the M21A's velocity issue, gotta agree there. There's a lot of velocity lost in that short a barrel.
Told the story before, but one time out shooting with a brother-in-law, had 21A and Ruger Mk2 with 5 1/2" barrel. Shooting same ammo from both - Federal "Hi-Power" 40-grain copper solids; "target" was an old washing machine somebody had dumped.
Shooting at probably 10-15 yards, the Mk2's bullets would penetrate and either badly dimple or penetrate the much-heavier steel of the inner tub. From the 21A, not one bullet dimpled the inner tub, because not one penetrated even the thin outer sheet metal. You could actually see the bullet landing in the grass after bouncing off. VERY disheartening to see, as the 21A was my pocket gun at the time; wasn't long after that, that I switched to the lighter, smaller, more powerful P32 for pocket carry.
Not knocking the 21A, still have it. For a small, concealable 22, it's hard to beat; and if I wanted a small suppressed .22 pistol, it would make a great choice.
Just commenting on the velocity loss from that short a barrel; it's a very real issue to keep in mind if using one for defensive purposes.
if u've got ENOUGH velocity and penetration,more isn't NEEDED. Hey, <font color=red>*</font><font color=red>*</font><font color=red>*</font><font color=red>*</font><font color=red>*</font>, when have the 22unit for the AR, u dont NEEDmuch inthe way of range or power out of the M21.
M21,at 5m,WILL knock you for a loop with a skull hit, and that's asmuch power as is needed. At least it can be ccw'd, and SUDDENLY draw and hit with,while wearing a backpack,unlike the canned Ruger. There's just no place to PUT an 11" long pistol, and both conceal it and have swift access to it, given the restrictions of the backpack.
if the CARis concealed in the pack,the M21 comesout of the thigh pocket and goes into either the fanny pack (top opening) at the navel,or somewhere IWB, (no fanny pack).
Just because YOU can't get-by with a "mere" 30 lbs of non-fighting gear doesn'tmean your BETTERS can't do so. It just means that you are INFERIOR,that's all.
Ruger Mk II goes rather nicely with my M1A. As for defensive handguns at times I find myself divided between a 1911 in .45 or a S&W M66, 4". If the balloon ever went up here, frel dogs and rattlesnakes would be a definite problem that would have to be considered.
