I tried Varget in my 21" barreled 375JDJ Contender carbine with 260gr Accubonds I didn't get the velocities I was looking for max loads = 2230fps
I tried other powders and ended up using IMR4064 = 2280fps - 2300fps average velocities and amazingly accurate.
I have a Leupold 2.5-8X B&C reticle scope on the rifle with these 260gr loads the main cross hair is sighted in 1" high @ 100 yards the first B&C reticle down = 1" high @ 200 yards and the second B&C reticle line down is dead on @ 300 yards and my ballistic calculator shows that the 260gr Accubond is still doing 1800fps so due to its construction is designed to expand at that velocity = 300 yard thumper...
The rifle in my avatar pic is my 375JDJ...
edit to change powder to the correct powder I am using
IMR4064 not H322 Oooops...
