I ran the numbers for this load. All generic to QuickLoad and berger ballistics app.
18" bbl, 36.54 grains of Varget begets 2182 ft/s at the muzzle.
At 300 yards, 1756 ft/s and 1370 ft/lbs of energy.
Drops 23" at 300 yards with a 100 yard zero, or 7.3 moa
Drifts 8.5" at 300 yards or 2.7 moa in a full value 10 mph wind
This is at sea level, elevation will work in your favor.
300 yards is on the edge for advertised bullet performance
With a 10 twist bbl your bullet will marginally stable, this will decrease the effective BC so ballistic numbers will be less/worse.
A 9 twist will offer full BC of the bullet.
As always work up any load to assure safety in your rifle.
