Compressed loads...or change powder? - AR15.Com Archive

One of the things you have to watch out for when doing compressed loads. When seating heavy (longer) bullets. Is your OAL. Sometimes the powder will push the bullets back out of the case after seating. Measure your OAL, wait about 30 minutes and check again. You have to have good neck tension or a heavy crimp to hold the bullet in place.

As for burning rate. Ideally you what the powder to burn within about 3" from the end of the barrel. Burn too quickly, you get low velocity. Burn too fast, you get big muzzle flash, and a dirty barrel.

It's been a week, all good. The 4064 are big cylinders so lots of room after being crushed I'm sure some broke and just filled the gaps. I'd be more worried with ball powder doing this. Only issue I noticed is I have to use LC brass. All others fill up into tthe neck.

Brass from different manufacturers have different internal volumes. Also from lot to lot from the same manufacturer may be different too. This will have an effect on how much you can fill a case and on velocity too.

I gotcha. I'll just keep an eye on these with bullet and powder and cases.

So what am I looking for though in the end? Use a chronograph and try and get the bullets as fast as possible without blowing the case/primer/me up? I'm sure even a slow 223 can be accurate to a distance. I've just never done distance. I know at 100 yards my 10" is dead on but is it deadly if only a few ftps cause the barrels so small?

I know any reload I've done and any ammo I've shot doesn't even touch my ar500 plate. But a guy with normal 5.56 FMJ 55gr out of a 20" barrel blasted right through like a knife through butter. I'm hoping this 16" 416 barrel is a little more powerful.

My AR has a 16" SS bull barrel. I normally clover leaf my groups at 100m's. At 500m's, on a good day. I can shoot 2" groups. My buddy can shoot my AR out to 700m's no problem.

I use either the Sierra 69gr Match or the Hornady 68gr Match bullets, with Norma brass, CCI 400 primers. I want to try the Berger 70gr VLD bullets next.

A number of years ago, I had Accuracy Rifle Systems build a mini-14 for me. The only part of the rifle that is Ruger is the receiver. It has a 1" lothar Walther barrel, about 20" long, Hogue stock, new gas block, you name it. With a cheap scope, it shot .5 at 100 yards bench rested. I went through all the protocols, 1 shot, clean it, for 20 rounds. Took forever. Then 3 shots clean it for 20 rounds. And then I put it away. Most accurate rifle I've ever fired but what the heck do I need with a $1300 dollar .223 rifle in mini-14? The owner has passed away and I bet they went out of business. Cool guy too. Talked to him before he died. Anyone know in this current climate is it worth trying to sell or just keep?

But what are you looking for with your reloads? Just accuracy or speed also as you test so you know it's not only on point but can also knock something down.
