Smokey...
I agree with Mathman in that you'd be better served by a 150 grain bullet of your choice for deer. You don't need a 165 grain bullet for deer.
To maintain a high degree of original bullet weight, I'd suggest one of the excellent 150 grain bonded core bullets over 40.8 grains of H4895.
My hunting load (deer) in my .300 Savage is 40.8 grains (40.9 grains is a maximum load) of H4895 behind a 150 grain Nosler Ballistic Tip bullet sparked by a standard Winchester large rifle primer in Winchester cases with the overall cartridge length with bullet at the maximum lenght (2.60-inches).
The above load gives me a muzzle velocity of 2635 fps out of my Model 99's 24-inch barrel regardless of outside air temperature since H4895 is one of Hodgdon's "EXTREME" rifle powders which is advertised (and I've found to be true) as NOT being effected by air temperature. I.E., your cartridge won't lose muzzle velocity as the air temperature drops.
This load has a point-blank-range of 250 yards wherein the bullet doesn't rise or fall more than 3 inches above or below the line-of-sight if sighted in dead center on a small target paster at 25 yards.
Since a deer's "kill zone" is about 9-inches in diameter, if your rifle is sighted in as recommended above, you can hold "dead-on" the desired point of impact out to 250 yards and your bullet should strike within a deer's "kill zone" from your rifle's muzzle all the way out to 250 yards.
Naturally, you should re-check the bullet strike at 100 yards if possible. Your rounds should "group" about 2� inches high at 100 yards.
I hope this is of help to you... good hunting!
