Sean Hannity is breaking news from his affiliate WMAL. The task force investigating the sniper shootings is searching a residence in Baltimore. Apparently, a white van has been impounded, an AR-15 has been found in the residence, and a man is being questioned by the FBI. The FBI is saying that he is "not a suspect."
AAAARRRRGGGGHHHHH!
Anybody who says a .308 isn't "powerful" can't be serious. Especially not when it comes to "soft targets" like humans. There are a LOT of .308 bore 1,000 yard match rifles out there,and damn few (if any).375 Magnum match rifles. The ballistic coeffecient works against you on the 375 bullets when it comes to long range shooting. As of a couple of years ago,I THINK the world record 5 shot group 6 inch at 1,000 yards was a 30 caliber bullet fired out of a 8mm Remington Magnum case. Being a traditionalist,I prefer a good old 300 H&H Magnum,but would be quite happy with a nice .308 bull barrell match rifle with good optics. I definitely would NOT pick a .375 H&H or any other .375 Magnum for a sniper rifle.
BTW,lest you think I am prejudiced against .375 caliber rounds,I created my own Wildcat 375 "short magnum" round while I was in gunsmith school. It was based on a blown out and improved 348 Winchester case. I built it on a Siamese Mauser action,and it gives 375 H&H ballistics with a medium action.
If someone does want to make this seem "Arabic", why write in English? I would think any Arab who wanted a declaration of Jihad to be found would be able to write it in Arabic, confident that it would get translated.
On the other hand, I find myself wondering if this guy's statement of Jihad might be directed against AQ, as in "You want war!? I'll show you war!!"
You noted: At point-blank range, the .223 is more powerful than any of these cartridges, and, being a rifle cartridge, holds that energy for much longer distances. At 100 yards, the .223 is still delivering about 900-1000 ft-lbs of energy. The wound characteristics of the .223 are also notoriously destructive, with "tumbling" and heavy fragmentation the norm. I have seen what this cartridge can do in the field, and it's not pretty, although it is admittedly inconsistent. Some shots (especially if bones aren't hit) are very clean, while others are a real horror show.
What would be the foot pounds at muzzle and 100 yards if the .223 was fired from a 12-13 pistol like a Contender?
Then the same data if fired from an 18 or 20 inch Bull Berry (I think that is the speciality barrel maker for after market Contender modification?
Thanks for your data. Seems like too many people are trying to make the .223 a more puny weapon than it is is reality.
An unconfirmed rumor, but still interesting.
The majority of even the pistol rounds will shoot through car doors,as will ALL rifle calibers. The only exceptions in the rifle calibers are the ones loaded with thin-jacketed "varmit bullets". This then is the fault of the bullet,not the caliber. The .223 military ball round will shoot through a 1/4 plate of mild steel at more 200 yards.
That was just there so the driver could get a good parking spot at the Saudi Embassy.
There's a certain amount of voodoo surrounding .223 loads for the Contender -- a lot of shooters roll their own. I don't have solid data on factory loads (such as the Winchester NATO load performance in the Contender), but I'm willing to estimate, based on some extrapolation of velocity/energy drops from AR-15-type carbines and pistols, that with a standard load you'll see muzzle velocities of around 2000 fps (with a large flash from powder continuing to burn outside the barrel), with corresponding energies around 450 ft-lbs or so. But that's a very vague guess, it really depends heavily on how fast the powder is.
Also, all my experience is with 55 grain bullets. I really haven't taken an interest in the heavier bullets, and the performance of NATOs 62-grain FMC M-855 in shorter-barreled weapons such as the M4 has been brought into question. I've tried the 62-grain rounds among various rifles in my AR collection and found them wanting. I know the FBI's CQB assessment of the performance of heavier bullets fired from short-barrelled weapons was unfavorable versus the classic 55 grain weight.
Then the same data if fired from an 18 or 20 inch Bull Berry (I think that is the speciality barrel maker for after market Contender modification?
With the longer barrel, you can certainly expect more juice. You might see velocities up around 2600-2800 fps or more. Again, though, I'm not really sure about the shorter barrels, but know they don't tend to yield 3250 fps velocities. The manufacturer should supply some performance data along with their barrels -- at least if they want to sell barrels to competitors.
Thanks for your data. Seems like too many people are trying to make the .223 a more puny weapon than it is is reality.
Well, please accept the disclaimer that I'm not offering reloading data or anything like that. These are my observations and estimates. I recommend getting solid numbers from authoritative manuals before trying anything fancy with loads. :^)
As for .223, it is far and away the centerfire rifle cartridge I burn the most of, and almost all of my black guns are chambered for it (it seems to fit the Steyr AUGs like a glove). I also like my other battle rifles in other calibers, particularly my DSArms FAL Carbine clone, but in my opinion, .223 is optimal for my type of shooting (quality and quantity).
I'm not saying the .223 is up there with the .460 Weatherby Magnum or other bruiser cartridges. Nor is it the equal of the various ~.30 caliber chamberings. It is a small caliber round. But it is a capable tradeoff between size and performance, is the centerfire rifle cartridge I shoot the most because it is good all around, and its ability to kill people is extremely well documented.
LOL. It takes a village to raise a sniper.
Don't believe everything the police tell you. They test only "service loads",for one thing. I can guarantee you that either a 44 Mag or a .223 will shoot through both sides of a car with the proper bullets.
