Some of this is repeat info that I posted in another area of the forums. But snox801 reminded me of this MOA Challenge post. This is definitely my best group I've shot with an AR.
-8 shots in 1/4 inch at 100 yards.
-Cheap Del-Ton Lite model AR15.
-Original 16 inch 1:9 twist standard contour barrel.
-Stock trigger except for I changed the springs and added a take up set screw.
-Burris fixed 3x scope.
-Original non free floated forearm guard.
-$15 muzzle brake I got from Amazon. Not sure who makes it.
-I did recently add that $3 Accu Wedge but not sure if it did anything.
-I did not use high end brass for reloading this ammo.
-I didn't measure every powder throw. I just threw directly into the case from a Lee perfect powder measure.
-The powder I used is old as hell. I bought 3 jugs of it at an estate sale last summer.
-I did uniform the flash holes of the brass.
-I used Lee Dies and did also use the Lee factory crimp die.
-Measured OAL on the picture was using a Hornady comparator on my calipers.
-The COAL is as long as it can possibly be and still fit into a magazine. And I did not single feed to get these results.
-Shot using stacked up bags in the front and a rear bag.
-And one last thing; when testing reloads I always wait a good bit of time between shots for the barrel to cool. It was getting dark on me fast yesterday and I shot this group straight without waiting. But I do know, this barrel starts walking if it gets heated. I do not think I could have shot many more and kept the accuracy without letting the barrel cool.
These are not my typical results. Most of the time this AR is an 1.25 inch shooter with factory cheap ammo. But with an 8 shot group instead of 3 or 5, I don't think it was luck either.
I'm been reloading about 6 months.
What do you guys think?
