I loaded some 225 grain Kodiak Bonded bullets to 2.875 COL and loaded 57.0 grains of VARGET for a 350 Rem Mag Ruger M77MKII.
I used Remington 9 1/2 primers and they were a little hard as my factory new firing pin spring seems a little weak. So I had three failures to fire from light strikes.
The average velocity was 2,536 fps with a 40 fps spread. The cases all came out with very dirty necks.
I was only able to obtain a 2.2 inch group with this load. I was hoping for a one hole group like Paul H shot using VARGET. It could be that my barrel is not free floated, or these Remington primers. There were no pressure signs.
