I have not seen much reloading data for 7mm PRC WITH Ramshot Grand so I just wanted to share some results I had.
Disclaimer these are my results not yours. Please be careful and work up your load safely.
Velocity measured with a labradar.
I'm using a bat machine vesper action with a preferred barrel blanks pre-fit barrel 24 inch with 1 inch integral muzzle brake 25 inch overall.
Hornady New brass. Hornady 160 CX bullet. Ram shotgrand powder. CCI 250 primers
Grains powder = velocity per second
68.0 = 2990
68.5 = 3000
69.0 = 2990
69.5 = 3020
70.0 = 3046
70.5 = 3083
71.0 = did not read
71.5 = 3120
72.0 = 3155
I was expecting to start seeing pressure signs at 71.5 grains but I did not see any pressure signs even at 72 grains.
My load was 2.5890 inches to ogive giving me 0.0600 inches jump.
