In this age of specialized rigs for every niche...does anyone out there still pursue the idea of a general purpose rifle? Something that's not perfect but will work for most of the hunting you do, or that you drag along as you go about your daily life.
I'm basically living the idea of a general purpose rifle.
I'm an old geezer now. My hunting buddies were always older than I am. They're now too dead to hunt or shoot. When each one of them rotated off the Mortal Coil, their guns and gear instantly became unwanted, burdensome, useless junk to the loved ones they left behind. Watching that same thing play out dozens of times finally convinced me that I didn't want my wife to have the burden of liquidating my former embarrassingly large firearm collection. Operating under the principle that if you want something done right, your best option is to do it yourself, I liquidated my gun collection over a span of five years, with the ultimate end goal being to have ONE rifle, ONE shotgun, ONE recreational handgun, and ONE EDC / CCW pistol to see me through my twilight years to the end of my days.
I didn't have to burn up brain cells cogitating over what the ONE rifle HAD to be. It was obvious that it was going to be an AR-15 A4 type and it was equally obvious that "some assembly would be required" in order to get exactly what I wanted, which generally isn't what people who "train" and "do carbine courses" and "prep" want out of their AR-15 style rifle.
I don't shoot CMP matches, engage in recreational target shooting, or hunt at night, so I don't need to hang flashlights and other tacti-cool crap off my rifle and I don't like the feel of aluminum handguards at all. I also don't care for the adjustable length butt stocks that are all the rage in AR-15 World today. Another thing I absolutely didn't want was a chrome lined, hammer-forged barrel on a recreational rifle that will never see a combat zone. Another thing I can live without is "free floating." I don't shoot with anything close to the kind of sling pressure that high-experts at the National Matches use. The idea of "free floating" an AR-15 stems from a need to get the forward sling swivel off the barrel, I don't have that need because I don't sling up tight.
I started with a stripped Anderson lower. Aside from a Rock River Arms 2 stage National Match trigger and high-speed hammer, an oversized barrel extension from White Oak, and a titanium barrel nut, the parts that I assembled my rifle with all came from a PSA 20" Freedom Classic Nitride rifle kit.
A real "service rifle" weighs 13.5 pounds and groups .5 MOA. Mine weighs 7,5 pounds to comply with current CMP modern military rifle rules., so I can use it for MMR or "Service Rifle" matches and it isn't too heavy to still-hunt with all day. It won't win bench-rest matches, but it will shoot 10 shots in 60 seconds around 1 MOA. As it is, it is already more fun than the Springfield Armory M-1A National Match that I used to have was. That was a 1.5 MOA rifle with match ammo.
As a hunting rifle, I had no doubt about the rifle's 5.56 NATO chambering. From 1984 to 2016, I filled 22 consecutive California A-Zone deer tags with the .223 Remington. During that time period, when hunting inland zones and out of state for mule deer, and doing that on foot, rather than off a horse, I used the pipsqueak .250 Savage, filling 21 mule deer tags, 2 caribou tags, 3 pronghorn tags, and one bull elk tag with it, as well as more feral swine than I can keep track of. If we would have had Varget and 77 grain TMK's in 1984, I could have taken my California mule deer with the .223 back then, as there's not enough terminal ballistic difference twixt the twain for a game animal to notice.
Here's what my old 100 grain Nosler Partition load did out of my 20" barreled Ruger M-77 Ultralight (Distance / Velocity / Energy):
M / 2620 / 1524
100 / 2352 / 1229
200 / 2100 / 980
300 / 1865 / 772
Here's what my 77 grain TMK load does out of my AR-15 rifle's 20" barrel:
M / 2854 / 1393
100 / 2636 / 1188
200 / 2428 / 1008
300 / 2229 / 850
If you tell someone that your favorite deer / varmint cartridge is the .250 Savage, they generally don't feel compelled to play the role of Morality Police. Tell them that you use 5.56 NATO, however, and you'll get an earfull of ethics lessons. What the numbers above don't demonstrate is how much better my current 5.56 NATO load is compared to the 100 grain Nosler Partition .250 Savage load is, The terminal effect, twixt the twain, is more or less the same. The 5.56 load, however, has a higher starting velocity on a bullet with a much better G1 BC, making it a bit easier to use because it shoots flatter and has greater wind-drift resistance.
70 grain mono-metal loads from the 5.56 more exactly duplicate the wound channel volume of my old .250 Savage load. The 77 grain TMK load makes wound channels with volume more equal to the Hornady LeveRevolution 160 grain factory load or hand-loaded duplicate. That load looks like this on paper:
M / 2360 / 1979
100 / 2112 / 1586
200 / 1881 /1257
300 / 1667 / 988
In the real world, a killing shot is a killing shot out to 300 yards with any of these and, in the real world, there's no such thing as deader than dead.
If all I wanted was a "huntin' rifle," any of these three are plenty for mule deer, pronghorn, and feral pigs, but the other two and the rifles I shot them out of fall shot of the 5.56 for "range toy" and organized match competition use.
TMI, I suppose, but that's why I settled on a 20" AR-15 in 5.56 NATO as my "general purpose" rifle.
Your mileage may vary.
