[QUOTE="cfvickers, post: 595604, member: 25488"] The last factory ammo I bought for my 300 win mag, and it will tell you how long it has been since I did, was Hornady Heavy Mag with a 180 interlock BTSP. Just off of memory I put a close estimate I think of the BC (.486) in the berger ballistic calculator at 3100 FPS. That stuff said 3120 and across a chronograph it was doing 3110 from my 24 inch barrel, and I bought 5 boxes of ammo from that lot because I was getting the most amazing and amazingly consistent 1 single hole groups unless I screwed them up (three shots not 5, never tried 5 at the time) at 100 yards I had ever seen. My SD on the ammo was about 8 and ES was right at 14. So I stuck with it for a while. that is where I got the numbers. They may be a little off but it was intended to be generic. I realize not all factory 180 grain 300 win mag ammo will achieve this. But any way. I completely understand your choice not to take a shot on a good bull past 650, a lot can go wrong past that, and crippling a beautiful animal like that would be sickening. I have passed on a few shots on very nice deer with mine because I was afraid if I did hit it it would not be a kill shot. I just understood you to be saying that it would not kill the elk, and to that I was just saying the required energy is there, it is just a matter of getting a good hit. [/QUOTE]
