Looking for a little feedback on a few reloads I worked up for my 6.5 Grendel:

Speed is Fine, Accuracy is final....but accurate hits at extremely high speed is final much faster.
I don't think you understand, these boys killed my dog!

Is this from a bolt gun or an AR platform?

The Grendel’s a low PSI cartridge, SAAMI spec for an AR is close to 52,000 PSI. Typically, in broad general terms, pressure signs on brass don't start showing up until the mid-50,000 PSI range. So, if you see pressure signs with an AR, you’ve more than likely already exceeded the SAAMI design spec. Know before you go! Just saying………

Bolt guns are a different animal and you can work up slowly and then back off when you see pressure signs starting to present.

This is an AR platform. Going out this morning with some additional charge weights and crono.

Primers are flat with really sharp firing pin indentations.

They are normally rounded, so something looks off to me.

Pressed them in very firm. They gotta be seated as far as they can go.

No I didn't. I'm not sure I have the proper tools to do this.
