That looks like a good load though I prefer to keep bullet shanks in front of the case shoulder.
According to Quickload
Input:
Cartridge 260 Rem
Barrel 22"
Bullet 130 Berger VLD
COAL 2.840"
Powder 38.5grain Varget
Calculated:
Shank seating depth .369" (about 0.1" behind the neck shoulder junction)
peak pressure 56977 psi. (94% SAAMI max a bit warm)
case fill 93.5% (good)
Muzzle velocity 2730 fps (good)
muzzle pressure 9676 psi (reasonable for a 22" barrel)
And per Quicktarget at 1000 yards at sea level STP it should give
Velocity 1446 fps
Energy 603 ft lbs
Time of flight 1.52 sec
total drop below bore line 364"
10 mph crosswind deflection 73.6"
If you chronograph it please post velocities and SDs. It would also be interesting how it groups at 1000 yards. It's still well supersonic at that distance.
