Re: CALIBER CHOICES
The scenario you gave about the 500 gr 51 cal. from the 408 (505 Gibbs) case at 2400 FPS is really not desirable at all to me.
To me it would be a fairly good "close range" Moose gun, if that.
After running it on the computer (programed a 51 cal bullet with a BC of .900 at 2400 FPS, I find that at 1000 yards it takes 33.7 MOA to reach the target and there is 2686 FP of energy left. At 2000 yards it takes 107.7 MOA to get to target and only 1186 FP of energy. This sucks.
Lets compare that to my 338/416 with a 300 gr MK at 3300 FPS which I do get.
At 1000 yards it takes 16 MOA and I have 3300 FP of energy left. At 2000 yards it takes 47.7 MOA and still has 1675 FP of energy left.
The 338/416 wins hands down.
I would be more inclined to neck the 505 Gibbs case down to 338, use a 40" barrel, 300 gr MKs or Warrens 270 Gr 338 bullets and try for 3500 FPS in a good heavy action.
If your going to a 50 Cal bore, may as well make it the 50 BMG and be done with it.
In my opinion and for me, it's the 338/416 or the 408 period for ultra longrange hunting for elk, deer or black bear.
Hope that answered your question.
