RE: 30-06 and grizzly
This one 20ft but there are others which spray further,
but IMO, then you will have a wind factor and you lose
some to the wind.
I take .338WinMag and .44Mag side arm,but If you are an expirienced
hunter you can use your 06 with no minimun than 200gr and place your
shot properly and not to long of a shot.
