Consistency is king in the world of long-range precision rifle.
An article I was reading recently was talking about losing 20 fps shot per shot by lax recoil technique. So I got to thinking and typing into my ballistics program.
Shooting 7.62 x 51 NATO 150 gr, BC .391, MV 2800 Typ, @ 1000m
- 1000 m @ 2800 fps Drop 1440 cm
- 1000 m @ 2780 fps Drop 1464 cm.
Or in old money, just under 9½ inches.
OK, point proven (sort of), but unless you are head shooting everything at 1000m, plus an expert at all the rest of the techno bits of shooting, it’s all pretty much for a narrow skill set i.e. for people who use bench rests at long ranges or snipers.
Real life and ‘little people’.
If the SHTF for those trying to stay alive in an Urban / Semi rural self-defense scenario it’s unlikely that you will be shooting much over 100 m.
Do the military still call building clearance “Widow Making”?
That ‘game’ causing more casualties to the good guys than any other activity.
One of the unanswered (but very opinionated) questions about urban weapons is “What is the ideal weapon and caliber for self-defense that meets all range and capability requirements?” I submit their isn’t one but 9×19 mm is a good start as is something you are comfortable and accurate with as good shot placement is vital no matter what caliber you are using.
My choice up to 100m in a sensible caliber is a compact, lightweight, bull-pup or very short carbine, or a MP5 format. Semi auto, and sensible (non PC) capacity magazines.
The ‘why’ is because there are many practical issues in working within an urban area, in buildings, like trying to swing a barrel quickly, in cramped conditions, and accurately onto close targets probably moving at high-speed.
So why these examples and not a handgun?
How many can achieve 3-4 MOA with a handgun at 100 m? (Excluding liars).
Anyway I’ve always preferred a stocked weapon over the spray and pray of a shotgun or pistol. That and unless you are trained and practiced in point shooting, using a pistol is a bitch as grip and sight mal alignment is enhanced in low light scenario.
Another small note. Are you a lover of shotguns?
If you are, at room ranges, you’ll know you still have to aim at a target as shot at close range doesn’t spread a lot. That and over 40 to 50 m, unless you are shooting slugs or sabot, your shot impact i.e. lead on target isn’t going to be all that great. On the other hand my listed types work well at all ranges from up close and personal and out to 100m.
Some will bleat short barrels aren’t accurate!
At 100 m or less, just how accurate do you need to be?
||100 m (in)
||50 m (in)
||20 m (in)
Before anyone says my MOA figures are wrong, they were averaged out from multiple user reported MOA and not factory spec.
As for real life? The only one I’ve fired is the MP5 and it never came off-center mass.
Incidentally, have you thought about how fast those sort of distances can be covered if someone is after you?
||4 to 5
|Dash to Cover
I also think (nay hope) I’ve just highlighted the disaster that is current thinking among ‘Hollywood’ survivalists. “I own a handgun so everything is covered”.
Sights? I’m not a fan of iron sights in urban work preferring a QR (red dot) as I always find iron in dim conditions another bitch. Having said that I’m not a fan of laser.
Is that it?
Not for me and I want to quickly mention SOUND aka Boom in a confined space. Firing or taking fire in an enclosed area without ear protection is to be HAMMERED BY SOUND. Almost all firearms create noise that is over the 140 dB level. That is beyond ‘pain threshold’ and if you aren’t careful you can be partially ‘sound blinded’ aka deafened. That can really screw up your capability for clear thinking and your equilibrium.
As a result reaction time slows and your survivability drops.
So If you are going into a hot zone, think ear protection.
Hows about talking to others, communications, or just listening?
You can buy intelligent (aka ‘Smart’ headsets) or earplugs with communications built-in. Both can plug into a radio, and both intelligently limit sound levels. A few even draw power from the radio so no batteries! (Boy I wish I’d had access to those years ago). Or for those simple moments in life you could use:
Expert. Yeah but you don’t have time to don ear protection in an ambush!
OK I agree. But not every scenario is an ambush is it?
If you are entering a known hot zone, I again say, what is it to don ear protection? 2 maybe 3 seconds?
Get woken at night by an intruder, what’s 2-3 seconds (unless they are in the same room). Process being make weapon ready and then plug up them ears.
And finally (because I’ve just looked at the word count and I’m thinking Oops).
Everything I’ve just scribbled is subjective but I would also remind you that disaster is generally a noise maker in its own right. If not the event, I do wish the emergency services had volume controls on their two tones and sirens.
That’s why my poor man’s PPE kit includes cheapo foam ear plugs.
