    I have two 300 BOs.

    A 16 inch and a 10 inch.

    I use 200m for supers and 100m for subs as a rule of thumb.

    Cool. Kind of along the lines of what I was thinking, and given your background I'll make note of it.

    I have no special, tactical experience with the round.
    I only have a fraction of a perfect of experience with it on animals vs 30-06, .270, etc.

    With longer range man stoppers and game droppers, you are typically dealing with 3000fps. Sometimes a little less, sometimes a good bit more.

    My opinion is mainly based on range time only.
    For subs you want to be not much over 1000fps.
    Sound really refracts and seems louder and travels farther in the cold, and cracking the speed of sound is easier when you are freezing your ass off. Playing at the desert range at 110 degrees as your only use you can use faster subs, but for simplicity let’s round off to 1000.

    The 300 Subs act a lot like 147gn 9mm, 165gn 40, 185-200 45ACP, 45 Colt (factory type loads- no 44Mag rivaling handloads for your Ruger or Marlin), and real light 38s.
    While some of these hit harder or lighter, they have pretty similar trajectories, and pretty similar run out of oomph ranges.


    The supers act a hell of a lot like 30-30 and 7.62 x 39. Sort of in the middle between the 1000fps and 3000fps cartridges.
    You can play with your zero, or use BDC reticles, etc. but tend to drop a lot past 200.

    From talking to guys that drop a ton of animals with particular calibers,
    I add that in.

    For my ability, accuracy, calibers, guns, damage at that range, etc.
    My 1000 FPS-ish stuff my rule of thumb is 100m

    For 2000 FPS-ish stuff, 200m.

    For 3000 FPSish and up stuff, 300m.

    Sure, if you are a marauding post apoptalypic war lord coming at me on a motorcycle with an Uzi mounted to the headlight 500m away, I’ll try to wing it with any of the above.
