Help me explain this ???

Bottom Line is You, and I don't disagree, I'm merely cautioning against letting ES and SD rule the roost. Simply because those values can be lowered by larger data collection sizes, neck tension, primer selection (LR vs SR) and the list goes on.

i wasnt trying to suggest that ES/SD should be the sole considered factor - sorry if it came across that way - just more so that even with smaller data sets that we can still use them in conjunction with accuracy to eliminate loads from further testing

one more tool in the toolbox if you will, not that it should be the only tool considered

I was actually hoping that you would pop in here to guide the OP through what the ES and SD actually mean, and how to use it effectively.
After all at one time most thought only ES was the answer, now we are chasing both ES and SD.

i'll happily leave that project to someone else this time around

No, your good at it haha ....

You didn't and my comments wasn't meant for you. The comment I was referring was to keep some from focusing just on that.

Exactly we agree whole heartily, I'm of the opinion that it should be included in the tool box. See I told you we agree a lot. You have said the exact same thing to me earlier when assisting me in a load. Which is why I said I know we agree to a huge extent. I just suck at conveying my thoughts some times.

Im making a move away from the 55 grain and going to go with a heavier bullet, i learned alot from trying to turn my 6mm creeedmoor into 22-250 proformance . Its just not meant for that . Im going to load some 80 grainers and go from there . I can not seat that little 55 grainer out for enough to get the velocity I was hoping . I will specify so i dont get killed on here !! Accuracy is my first priority . I was trying to achieve speed as well , i liked the idea of shooting a 55 grain at almost 4000 fps something the 22-250 can't quite achieve . I can with a 50 grainer in a 22-250 but not a 55 grain , but now understanding i probably should have bought a 243 instead . Well I learned alot and know that I need to focus on what the cartridge was designed for the heavy longer bullets .

Not getting into the ES and SD conversation, I would agree with you on moving from a 55 gr bullet to an 80 gr bullet in. your 6CM. The reason I say this is that I shoot both a 220 Swift and a 243 Win. The Swift is made to shoot smaller bullet very fast while I believe the 243 Win has a sweet spot around that 80 gr mark but that is just my opinion. I worked up a load for my 243 Win (rifle is a Tikka T3x Super Lite) using the Barnes 80 gr TTSX bullet and I absolutely love not only the accuracy but its performance.
If you have not already, give those Barnes 80 gr TTSX bullets a try.

all good!

sometimes slicing quotes comes across wierd... you had my quote in there above your comment as a whole and i was like "did i not have enough coffee when i wrote that and missed something" and actually went back to double check my post LOL

Little update with the new 80 grain eld vt with staball 6.5 powder 46.5 grains. Oal 2.790 im on to something here . Sd was 7 feet . I think im going to play with some tenth of a grain increments. That shot to left was me bad squeeze so I fired a six shot . I think with maybe charge and bullet seating depth playing around I can find a great load here. I think I might rip this scrappy trigger out too and put a timeny in . Its like 3.5 pounds and doesn't break clean I feel . I think it might help .

The nosler book also said 3800 fps and I only iam getting 3400 at max. Any input would appreciated as im always learning

Here lies your problem - Nosler book.

I will probably get a lot of flack over this, but, I have never done any of my reloading using this book! Why, because the velocity were never even close to what my choreograph was reading. I tested 22-250, 7mm Mag, 270, 30-06, 308, and 300wsm.
All my loading was done using either the Speer or Hodgons manuals, for they proved to be the most accurate.
