"THE" 223 load thread....

Just to keep you happy... ;D

 

Apparently, that 23.3 8208 load with 77s and 80s flat hammers too...

Don't know the answer to the burn rate Q but Hodgdon have a fair bit of data on their site:

LOL! Yeah being that there wasn't much of "Long Range" being discussed. Anything from 600 yards in is "Mid-Range"!

 

bOY... yOU IS CRAZY,

 

No, I am a man! And no I am not crazy, I am eccentric, I just don't have the money to prove it!

 

Yes.

 

I would try the 25 grains of 2015BR or R10x. Try 24-24.5 first. Somewhere in there you will find you max pressure.

 

I hate these stupid CCI 400 primers!!! I had no idea they were thinner than my Federal 205s...

Last batch of processed and primed LC 223 I got was primed with CCI 400's. They are not worth a crap for heavy bullet loads.

 

Ya know, I never had problems with CCI-400s until recently and then I was experiencing about 25% pierced primers.

Made a switch to CCI-450s shooting the same loads, and those primers look perfect.

 

It's been pretty hot... Your loads might have been fine in the winter.

 

I tested loads in my Savage 1-8 Benchmark barreled bipod gun this weekend.

R-15 at 24.5 grain with 77 SMK shot kinda kick *** considering the horrid conditions. I was shooting at 400 yards and could barely make out the orange quarter sized spot on the target. Mirage was UMMMM heavy!!!

I was seeing about 1 inch of vertical. Lots of touching bullets in 10 shot strings.

Do not use CCI 400's with this load. I had some real primer problems and I never had these problems with 205M primers, even in a AR-15.

I shot the 23.3 8208 load. The group was round but not nearly as small as the R-15 load. Also, pressure was low, so I assume I could go up.

There was a FOOT of vertical difference between the two loads at 400 yards.... The 8208 was slower by a lot... I apparently need to go up.

The 8208 runs like a dream in the progressive. It throws to within .1 grain.

 

I've never had any problems with the 400s. Then again I'm only running up to 69s. We'll see about the new batch as I just picked up another 2k of them along with 2k of the 200s.

 

A variance of +/- .1 is enough in the .223 to give you verticale provided that everything else is good to go.

 

Not to be argumentative, because I am sure you have lots of experience with this, but isn;t that the point of OCW and ladder testing? Finding the "dead spot" in the charge amount where a slight change in charge does nothing?

I would think shooting 90's like you do would make it much worse...

 

I am going to thick cup primers only. The 400's are not really made for high pressure loads at all. In fact, I think CCI recommends these primers only for the low pressure cartridges under 40k PSI.

I have Remington 7 1/2s and CCI 450s so I'm good.... The local store carries the new Wolf 223 primers, which is supposed to be made for high pressure loads.

 

Everything is more criticle at 1K and with the small case of the 223, exspounds on it.

 

I'm almost glad that I can only shoot to 400. If I had access to 1K I'd have to get another scope or build some more drop into this one. Currently (theoretically) I can dial out to 800.
