Just finished my 6mm arc build. I chose to run 70 grain nosler varmageddon bullets. With cfe223 (it’s what I have and easy to find)
Max OAL is 2.090 I loaded to 2.094 cause I had so much jump.
My jam is 2.230
Is that way to much jump for an ar?
If I increase the OAL is that going to cause pressure To go up or down?
I fired a few rounds today to check pressure and have no pressure signs. And cycled just fine. All the way to max load data of 33.0gr.
Now I’ll put my thermal on and go sight in and shoot for accuracy
