Ar

I swapped some uppers and sights on a couple of my ARs this weekend. On my scoped rifle I sighted in at 25 yards and when I moved the target out to 100, I was 8-10 inches high? After adjustment I was getting 1" groups using the tailgate from my wrangler for a rest. I'm confident that shooting from a bench it'll do well under an inch.

Thats good shooting. My completely stock 70's Colt SP-1 will do 3-4 inches bench rested through the factory irons. I can tighten it up some with meticulously sorted brass and bullets. Trimming once fired brass for consistent length, weighing each and every charge and bullet but when I do 223. I usually load several hundred with various brass. I drop charges a little more than 10% below max depending on the measurer rather than scale each load. I've cut the charge of Win 748 powder 20-25% below max, My AR still functions 100% but the shot to shot accuracy takes a nose dive. The same reduced charge was iffy in my shooting bud's Mini-14.

1" at 100 from an AR off the back of the truck is good.

 

 

Years ago, I loaded up a bunch of ammo on my Dillon 550B. Just chucked it through with ultra cheapo 55GR spitzer bullets (~3 cents ea back in the 80's), milsurp H335 powder, whatever mixture of brass (mil surp, commercial, all mixed up). Went boom in the AR. In my 14" contender, it shot sub MOA off a sandbag with a Burris 3-9 extended eye relief. You could drill things you couldn't see without the 9x scope. Golf balls at 100 yards were not even challenging.

I've watched some younger shooters do some amazing shooting with heavy barreled AR's at a 200 yard public range. With free floated heavy barrels and an improved rifling twist rate. These modern AR's are very capable of match grade accuracy.

 

Doc, years ago as we packed up at the end of a Javalina hunt. I watched two guys in our group do some spectacular shooting rolling beer and pop cans at about 100 yards. One had a 223 Contender the other had a real classic, a Remington 221 Fireball. I don't recall either of them missing a shot.

 

A co-worker picked up a Contender chambered in 35 Remington at a yard sale on his delivery route. After work we headed to the desert to shoot it and I only shot it just once, my co-worker had the nerve to shoot it twice. No way would I ever shoot it again with factory ammo. I think the bullet weight was in the 225-250 range. After the immediate sharp pain went away. My hand and wrist felt like it was vibrating for the next hour. I can't recall the number but do recall he got it cheap along with a SKS. After shooting the T/C, it was easy to understand why somebody wanted to sell it.
