do you usually load your charge weights for 223 in 0.5 grain increments?  that equates to an incremental increase of over 2%.
given the low charge weights of 223, i'm almost certain that you're missing nodes in your 0.5 grain jumps.
I agree. I usually follow up with 0.2 grain jumps. For example, I might load 23.2 to 24.0 gn Varget next time. I'm not confident in my scale's ability to measure 0.1 increments, plus it's a huge pain in the ass.

I'm also basing the load data from Nosler. Notice in the spreadsheet, the Nosler FPS nearly matches the FPS from my first set but not the second set.

I agree with TooFewPews.
In my experience 77s don't start well till I hit about 2700 fps.

It's interesting that Nosler's data doesn't go past 2700 fps. What am I missing?

Ive clocked Atlanta Arms loads at 2900 but theyre likely using a canister grade powder not available to consumers.

Just out of curiosity, does Kevin and yourself load to mag length/2.260" or do you guys single load?

80s for sure beyond mag length ~2.450

I was playing with the Stability Calculator. http://www.jbmballistics.com/cgi-bin/jbmstab-5.1.cgi

"The Miller stability value. It should be between 1.3 and 2.0 to ensure stabilty (the military uses 1.5)."

The result was 1.835. The weird part is when I calculate the stability for the 62gn that I shot on 8/17, I get 3.059 but had the best accuracy yet with the rifle.  ???  Playing with the numbers, I should need a 1:10 to get the bullet stable.

there's only so much a program can account for.
As I stated before MANY have been down that path you are taking. A 1x7 will stabilize anything from 52 to 80s. I can say from experience and with different barrel makers from Wilson, Douglas and Shilen. Others have experienced the same with Kriegers as well.
What are you looking for in regards to reloading?

well there you go...
most of this thread the information you post in regards to reloading is so convoluted and irrelevant
you ask for feedback and many of us give it but yet you revert to your own resources so why bother asking questions in public?

Looking at the Nosler load data - they are using a 20" Pac Nor 1x7 twist. Pac Nor barrels also have different number of grooves which is not stated. That is a difference between your barrel and a PacNor. Notice that their loads are approaching 2700 with 24.0 RL15. That's the magic load there - and it is highlighted.

Makes sense. I remember the 24.0 gn of Varget was starting to crunch when inserting the bullet. I might have to use the electric toothbrush trick to get more extruded powder into the case and the almost 1" bullet.

Processing the .223 brass. There were some sporadic primer flattening but no cratering. The top two in photo are 23.0gn Varget and bottom two are 24.0gn. The two on the right are flatter then the left two. I can't tell which set they were in, only the charge. Perhaps I was drinking too many vodka margaritas at the time.

You're drinking alcohol and reloading? ::)

Don't do that.

This thread is already a misadventure from page 1.

No.
Go down that road - but don't drink while you are doing it.
Good luck.  :thumbsup:

I kind of have to agree. I haven't followed this thread religiously but from the info I have seen, I have a hard time wrapping my head around it. I really don't understand the max and mean thing. I'm from the school that 3 shots test the load, 5 shots test the gun, 10 shots test the shooter theory. If your load developement doesn't follow a consistent path, all the info you get is irrelevant. If precision is your goal, I would suggest a more sytematic approach to your load developement. If precision/accuracy is not your goal, then disreagard my post.

Not trying to defend RK here as he has many times done this to my attempts to help him as well. But the title to his post is his adventure/misadventure in reloading. So I have decided to take this posting as more of a story or a novel rather than a serious attempt at trying to ascertain relevant information to attain an ultimate goal. Therefore I believe his questions and requests for help are actually rhetorical and are just his way of saying his findings are curious to him rather than actually asking us for his help.

I could certainly be wrong. But I think this post is just his attempt to share information and tell his story.
