Thanks Truckguy you have given almost exactly what I need. I’m working with 88gr ELD MATCH but I can figure that out. Still waiting on an X Caliber prefix barrel for a Savage
 
X caliber should be GREAT. Let us know your results, there is not very much 22 creedmoor load data available.
 
Great now there are 3 or 4 of use playing with a wildcat. Problem is it’s not my rifle I’m building it for a friend. However I will get to do the break in on it
 
Ok here goes. It’s a simple build we’re using a chassis and action from a Savage 10 Stealth has a new Basix trigger and waiting for an X Caliber pre fit 22 inch 7 1/2 twist stainless cryogenically treat barrel.88gr Hornady ELD match Gunwerks 22 creed brass and Hornady 6.5 necked down. That’s about the size of it. Just waiting for the barrel so break in cat start.
 
What are you using for a COAL with the 85.5gr Berger’s and what is the length of said bullet
 
I would run your own measurements as every rifle is chambered slightly different. Over all length of actual bullet is 1.167
 
Thanks I’m just trying to compile as much info as possible before barrel gets here . I have loaded 25 break in rounds with 38gr of H-4350 and a 210M primer and barely seated the bullets. Thanks
 
Just finished up 1st trip to range with my new 22CM. Looking for some help or suggestions.
The Particulars:
Ruger RPR brand new action
Proof Carbon 22" 1-8 twist new barrel
Peterson brass 22CM SRP new brass
VitaVhouri N555 powder
Nolser 85gr RDF Loaded .004 jump basically to the lands
Federal SRP
So I loaded 10 break in rounds at 36gr to check overall function or rifle and load. Avg velocity was 2818fps. No pressure signs. All is good. These are the 10 rounds on the left in the picture.
Then began a pressure test ladder to find where the limits might be. Started at 36.5gr and moved up in .5gr increments to 40gr.
Was hoping to see somewhere around 3100fps before pressure signs. Started seeing the primers flatten and back out at 38gr at 39gr my son said I better stop but I went ahead and put the 40gr in the mag and promptly blew the primer. Other than the Primer signs no other signs of pressure. No sticky bolt, no swipe marks, no extraction issues.
If I go with the last safe load indicated then max velocity is around 2900fps. Kinda disappointing.
Any suggestions if I want to shoot 85-90 grain projectiles?
Do I need to bush the firing pin on a RPR to handle the small rifle primer?
Pics attached. Shows bolt face after range trip and the case heads 10 on left are 36gr. 8 on right start at 36.5 on lower left and the 40gr blowout on the upper right.
Appreciate any input.

It looks like the primers are getting flatter as you progressed up in grains, so if that’s the case then the issue isn’t just the bolt. The weird thing about that is your 36gr loads look to be flattening primers in some cases, but not others. How are you measuring charges when loading?

I don’t have experience with N555 but at least on the burn chart it is in the right area. On a different note, I think you have a marginally slow twist rate for the bullets you want to shoot.
 
All loads dropped with Chargemaster and then trickled up to exact grain weight with Redding balance beam. Should be able to handle 85gr with N555 according to other comments using N555 up to 90gr with 1-8 twist. We will see. Have reloaded the same cases now that they are closer to chamber size with 2thou bump. Next test will be the same charge weights with the Federal SRP and then CCI 400 and 450 to see if anything changes. Plan to probably run some 75gr ELD and see what happens as well. Will report after testing. Thanks for the input. Jerry V
