New 22 Creedmoor build

The 88gn bullets seem to like magnum speed (burnrate) powder, staball hd seemed run consistent.
I too seen pressure signs with 6.5staball pretty early.... almost like pressure spikes.
My very limited 2cents.

@ killing Time,..
I'd be real interested to see, MORE group Testing with, the 73 gr. ELD-M's and some, lower chg's of, StaBall 65 for "best Accuracy",.. Sub,.. 43 grains of, StaBall 65 ( like 41.5 to, 42.9 grs ). ( I'm curious ! )
Also what, Brass / Primers, are you using ?
Thanks in advance !

This is the other groups I shot yesterday before I froze out. These are load development groups just trying to see what the gun likes. The first is a 88 gr ELD-M with 41.0 gr Superformance. Not too bad, especially with how Superformance is not supposed to like it cold. The second is again 88 gr ELD-M with 40.0 gr of StaBall 6.5. This load was a little too hot. I had signs of pressure from this one. And the last one is 73 gr ELD-M with 43.0 gr of StaBall 6.5. No signs of pressure with this one but I may back the charge down a little next time just to see if it tightens up the group. I have several rounds loaded to try with this gun and I'll be glad to show the results if you want. I've got some Bergers loaded that I have high hopes for.
Yup,. I'd Like to See, all / any group's of, 73 grain ELD-M's with, StaBall 65 powder
TIA !
