Minimum impact energy for antelope?

Many LR hunters are of the opinion that 1000 foot pounds is the magic minimum number for deer and 1500 foot pounds for elk. What about antelope? Do you all think 700-750 foot pounds is adequete for a super light skinned/boned narrow animal such as an antelope? Provided the bullet expanded and tore a proper hole, why would 700-750# not be enough?

I would be good with it. Providing good placment was a given. But would like a 210 better.

So whats up? You thinking a sub-sonic build?

Re: Minimum impact energy for antelope?

Just looked back at a shot I took a few years ago. 107 SMK in my 6mmbr. Yote was facing me at 651 yards. Bullet hit between the front shoulders and exited under the tail with a 1" exit. Full length pass through.

Velocity at impact 1860 fps
Energy was 822 ft lbs.

Just for a referance. I know that is 100 lbs more but I would do a small deer at this same distance with no second thoughts after seeing this.

No. Thats just about all I can milk out of my 308 at 1000 yards.

I am going to try some of Rich's 190s soon. If those will expand at 1600'/sec, these would get me to 1000'/# at 1000 yards.

I can get the 200SGK to about 990'/# at 1K but my rifle likes the 168-190s the best.
