I have a 26" barrel, 1/10 twist, remington action, in a 300 win mag. I am a newbie to long range shooting and reloading. I am wondering what would be the best bullet for target and hunting over 190 grains. I want one bullet so I don't have to switch zeros. Any information on factory ammo, or reloading info. would be much appreciated. I am looking for accuracy on targets out to 1200 and killing animals at 800-1000 (NOT UNTIL I PRACTICE FOR SEVERAL YEARS). Thanks for looking.
