I bought some 150 grain Accubonds at the Pro Shop last week and loaded them for my .300 RUM @ about 3500 fps. Anyway the guy at the desk told me if I was shooting this bullet in this caliber, he wouldn't recommend shooting at an antelope if it was closer than 100 yards. This made me a little nervous so I decided to try a penetration test. Real high tech newspaper test. I comressed newspaper down to 24" and shot from 50 yds away. It blew the paper back 3' and penetrated about 2/3rds thru, cutting a hole 3'' wide. The bullet weighed 87.3 grains and looked like a Chinese throwing star when I removed it. Should I worry about penetration on an antelope? I really like this load and bullet with 5 shots @ 100 yds all touching, so I don't want to change it.
 
I think you are fine, the NAB was designed to stay together. For a more realistic test, cmpletely soak the paper then shoot into it. Dry paper is very hard on bullets.
 
OTOH, even wet newsprint is a poor substitute for lung tissue. Shoot an animal through the lungs and the bullet sees an inch of hide/fat/muscle, then two air-filled sacks with almost no resistance, then the muscle/fat/hide again. Hardly like a solid "brick" of muscle that the wet newsprint tries to replicate. But the paper is a decent replication of a shot through the paunch or the hams....

That said, I've used the wet paper to help evaluate bullets. If it does not expand in this, then it may not expand on lung shots, or even shots through the paunch.
 
First of all I havn't tried the AccuBond at 3500 fps. I have, several times in the past, hunted deer in California with a 22-250 at about that same velocity with a 60 grain hollowpoint. The term( one shot kill) would be an understatement. The shock at that speed is devestating and instant to the nervous system and it jellied the lung/liver. The antelope is about the same size and weight as a Cal. blacktail at 75 to 90 pounds. The point being that what the AccuBond will do cant be as dramatic as a thin hollowpoint but will certainly stop the antelope in it's tracks.. If the shot is that close you will probably hit it in the heart lung area and not do any more damage to the meat than any other bullet will.
The real story here is that you aren't likely to get a 100 yard shot at an antelope. At a half mile when you sneak your head and spotting scope over the hill for a look at the antelope you will find the antelope checking out what your wearing. They see reeaal good and are very un-aproachable most of the time. Your biggest problem is likely to be getting within 3 or 4 hundred yards for a close shot . For that the AccuBond is going to pay big dividends in accuracy and retained energy but they are thin, small, frail creatures and don't take a lot of knock down. Their strengths are their eyesight and speed. You have on your hands a non-problem unless you get unlucky and shoot him in the head and ruin the mount and any bullet would do that for you. Good luck. Oh yeah, that old trick about putting a piece of cloth on a limb and the antelope will get curious and come close and look at it really works, but no big bucks came only little ones and does. :)
 
Greg,

It sounds like you are good to go. I like to plan for the worst and hope for the best.
You have both ends covered my friend.

I suspect that a 150-gr. AccuBond in a 300 RUM at 3,500 + FPS will behave (on game) similar to my 30-06 shooting Winchester 180-gr. Nosler Ballistic Tips (BT's) at 2,750 FPS.

This heavy for caliber BT bullet has similar contours as the AccuBond with more aggressive jacket profiles than 165-gr. and lower BT's.
