What powder did you use?
222 Low-Drag
- Thread starter deadduck357
- Start date
The Hodgdon site shows 2800+FPS with an 80 g bullet in a 24” barrel 223.
Duck, what are the last two chrono readings in your last post? 224 Valkyrie?
You may have confused folks showing 3000+ FPS in your earlier posts that were the 224 Valkyrie???
So far if I’m understanding, your low drag cartridge is doing about what I would expect for the case you’ve partially described.

Those chrono are from the 222 Low-Drag, I don't own a 224 Valkyrie. Stated manufacturers 224V velocities for comparison purposes.
All velocity recordings posted here shown on chrono are with the 222 Low-Drag.
I don't comprehend your last paragraph. ??
222 Low-Drag with Hornady 88 gr ELD Match bullets.
Based so my superior google skills and photo extrapolation, these are the approximate case dimension I have determined.
- OAL of loaded round = 2.300"
- Case length = 1.52 to 1.55"
- Base to shoulder = ~1.22"
- Neck = 0.220"
- Shoulder angle 23 to 25degrees, my protractor wouldn't tell me exactly.
Kinda looks like he ran a 223 rem reamer in 0.200" short. deadduck357 will have to tell me how wrong I am.
Posts #6 and #101 chrono pics - one of the chrono readings in each had a title of Federal 224 V
It appeared to me your results were in line with what a 223 round would do.
You have pretty impressive skills, off just a bit on some and very close on another. The COL is 2.260".
I have a 222 Low-Drag reamer the gunsmith used.
If you're out of capacity without pressure, you need to go to a faster powder, like H335, Benchmark, IMR 3031, N133, Reloader 10X. Not too far up the scale, but a little bit.
You can check out hodgdon's relative burn rate chart to see how I got to those powders.

My apology for any confusion but like mentioned in post 106 any velocities stated for 224V or 223/5.56 are per the manufacturers published velocities. All chrono pics posted here are from the 222 Low-Drag.
A 223 with heavy secant bullets (ELD,VLD) at 2.260" mag length??
That's my thinking as well, bought some H335 and Benchmark. Thanks for the advise, let's me know I'm on the right track. Seems like I'm always buying new powder lol.
Yes I do look at their burn rate chart, just wish it was more thorough, not all powders are listed. Like where's A2200? Where does it fall?

Thank you, I also use that one. Their correlation is somewhat perplexing. Like why is H335 so much slower on the Accurate versus than on the Hodgdon (???).
Any new developments on the 222 LD?
Or is OP missing the fingers to update us after his over-pressure round finally caught up to him?

I think those charts are part art, part science. Some of the powders are so close together in burn rate that lot to lot variations or slightly different testing protocols will rearrange the list differently when you're looking at adjacent and closely related powders.

As LONG as you don't go faster than my LONG loaded 22 Nolser with 88ELDs, I'm OK
I'm also working on a .224 wildcat with more case capacity. Having a little trouble getting someone to make me a reamer though.

The balloon is what happens when you put a 22-250 load of powder in a 222 case and seat a bullet on top of it with an arbor press.
I would guess that the OP is busy learning how to respond with his new eye patch and prostetic fingers. Give it a little time, that's a lot to learn. Lol
