i would apprciate it that u dont tell me im overgunned or anything of the sort. im comfortable with this cartridge and every thing about the gun.
Ha, ha, he's ducking before any "shots" are fired
Some good advise noted above. 300Win.Mag. for deer - ok. There's no such thing as
"overkill" - dead is dead. It's your shoulder.
Given the ranges you noted, if you want to use 150gr. bullets I'd stick with nothing but the premium type such as Nosler Partitions, bonded cores, etc. Close range & high velocity, with the lighter/softer bullets can = blowups.
Better, I think, to go with heavier bullets such as the good quality 165gr. or even a
180gr. With the velocities you get out of the 300Win.Mag. you shouldn't have to worry too much about bullet drop at the longer ranges. In fact, at some point the heavier bullets will often have a flatter trajectory, and are not subject to as much wind drift.
Check out the ballistics tables for comparison purposes.
