Trying to outshoot 7.62 X 39 with .223

[Grizzman47]

The answer to the question is likely luck.

Okay…you don't have an established recipe with 69s. What bullet is it? I presume the powder is CFE223. What powder weights did you try? What brass, trimmed to what length? What's the COAL?

All of this matters if the goal is to achieve 1/2 MOA without luck.

You've got to be kidding? A pound of powder on a 223 platform for load development. That's some funny stuff. How about a bullet in the 55 to 69 gr weight then take the time to read a loading manual ( it's got recommended powder and twist used for testing) then do a simple ladder test . Probably figure it out in say just a few rounds. My 223 all shoot different gr weight bullets but they all shoot way better than what your posting. I can get my Contender pistol to shoot circles around the group your getting. It pays to know what your twist rate is and how to load for it.

I have no doubt that many people get 223 to shoot far better than I have managed, that's why I why I am developing a decent load.

No doubt about it, but it's consistent luck with that particular type of rifle.

Beginners luck.

Whats the SD on it, 100 yard groups don't always translate to 1000 yard groups. You can do things the hard way if you like. But there is plenty of good advise on this site for working up loads. I've never had a hand load NOT shoot sub 1/2moa. but I follow traditional load development and brass/bullet prep techniques. You seem to just close your eyes and point. Just got one done yesterday on a 6mm that's shooting .25 across 4gr charge weight with a single digit ES, at the start it was shooting 1.25" at 200 yds…but what do I know.

Also if you're going to pretend you're serious about analyzing loads, at a minimum please get yourself a rear bag and a bipod. Maybe a chrono as well.

I'm not pretending to be serious or anything apart from wanting a good repeatable .223 load. The last thing I need is a bipod and a rear bag, that kind of shooting does not interest me, I don't think it's practical.

This can't even be real .

The 69 grain bullets I have are PPU HP BT 69 grain Match. Yes the powder I tried is indeed CFE 223. I tried one load with 24 grains of powder. The COL was 2.250
It is my intention to make some different 69 loads today, but it will likely be a few days before I can shoot them as there is a storm on the horizon.

Shooting 2" groups and whining on the internet refusing to take solid advice isn't practical either, yet here you are.

Sounds like a good starting point. I have been pleasantly surprised by PPU components. Both the bullets and brass seem to meet my expectations. I would start .020 off the lands if magazine length permits. I've used CFE223 in my AR with 60 Sierra MK and got consistent 3/4 inch 5 shot groups. Some under some over. I think the gun will do better, but I need to change the stock to achieve better cheek weld. My main gripe with the AR platform. Luth-AR has a nice one with adjustable height cheek riser.

It's probably just the aliens again looking to probe you for all the answers . Maybe if you shoot straight up you'll hit them before you get a good probe put in

I looked in QL for a 69 grain PrviPartizan BTHP bullet, but it isn't listed. That's odd, since QL's bullet database is quite complete. Are these bullets pulled from loaded ammo, or new in the box? Does PPU use bullets from another manufacturer? When I select a 69 grain SMK, with 24 grains of CFE 223, the load is under 35,000 psi. What was your load data source?

When I'm looking for 1/2 MOA performance, I use SMKs, ELD-Ms, Scenars, A-Maxes, etc. I've approached 1/2 MOA with Hornady 55 grain SBT driven by AA 2230 through an unlined DPMS 1:9 twist 223 Remington AR, but it was luck that this barrel really liked this particular load, not my exceptional handloading skill.

I'm not whining at all, I'm as happy as can be I'm always happy to take solid advise when it's obviously so, if not I will disregard it.

I got my load info online, it was supposed to be good for a 1 inch at 200.

 

[Grizzman47]

I subbed in Hornady 68 grain HPBT (and changed to the standard case water capacity) and it shows a bit over 41,000 psi, 2620 fps (from a 20" barrel) and only 87% powder burnt. I suggest you ignore that data source.

What velocity are you getting from them?

As far as using a bipod and bag for load development.....the idea is to remove you from the equation. Using a sand bag up front and no shooting aid in the rear is more of a test of your ability than that of the load being tested.

Basic load data from several books. Most have twist rate and barrel length .Notice the twist rate listed for 40 gr .
