Bullets that expand at low velocity

Alright guys, I need some information on long range bullets. I am messing with a special lower velocity load for hunting in an area where I need to be quite, and very safe. I'm loading 155gr A-Max 30cal bullets @ 2,300 fps. I'm getting good accuracy, but I'm concerned with the expansion of the bullets at low impact velocity. I need a bullet that will expand well at impact velocities as low as 1,500 fps, but not explode @ 2,200 fps. Will the A-Max do the trick? My research tell's me that I have enough energy for the very small whitetails I will be shooting. I just need to know I'll have the expansion I need in soft tissue.

Re: Bullets that expand at low velocity

I don't know about the expansion you will get but if you are shooting whitetail's put the bullet into a front shoulder and even if it does not expand much they ain't going no where. The bone fragments and shock will do a number on them. You will most likely get pretty good expansion with the A-Max. Your best bet would be to go with a 125 gr Sierra or one of the bullets made for the 30-30 win. A 30 cal. pushing a 150 gr bullet 2200 fps will not be quite.

Have you considered a 30 cal bullet designed for handguns? How about a 30 cal varmint bullet? Put either one in the vitals of a whitetail and it's "good night Irene".

A 155 AMAX will NOT blow up at 2500 FPS impact (at least when it hits the rib cage, the shoulder bone might make her behave differently) AND it will open at velocities a bit less than 1500 FPS.

Re: Bullets that expand at low velocity

Thank you Gentlemen for your input,

RT2506: I have tried the 130gr. Hornady SP's over 46gr. of Benchmark. Year before last, I took 4 deer with that load. One was a head shot at 60-80 yards, another was a shot down through the lungs and removed the heart at about 20 yards, another was a heart/lung shot at about 80 yards, with the last being a high shoulder shot at 150. All were DRT except the 80 yard heart/lung shot. The only thing is that it sounds like a cannon going off in the little valley that I hunt. My wifes folks own a 50 acre farm with fussy female neighbors that don't like hunters. I try not to stir-up too much trouble, so I started developing this load (155 A-Max over 28gr. of SR-4759 @ ~ 2300 fps). This load is considerably less offensive to the ears. It sounds more like a 9mm.

Varmint Hunter: Yes, I have considered the pistol bullets, but the BC is so low. I want to be able to reach out to at least 300 yards. I would have to drive them much faster, with much more muzzle blast to accomplish this. I don't think the bullets can handle that kind of speed either.

Michael Eichele: Thank you for the expansion information on the A-Max. I will be making head and neck shots under 200 yards, and placing them in the vitals beyond that. Do you think that a 155 A-Max would break the shoulders of a small whitetail @ 1500 fps, or just break up the bullet?

Again, thank you gentlemen for your assistance, and nice to hear from you.

Re: Bullets that expand at low velocity

2000fps is a good rule of thumb for minimum impact velocity. I know the 7mm 168vld berger absolute minimum impact velocity is 1800fps due to inconsistent expansion(I mean either open up or zero expansion) under that 1800fps velocity.

In what I have seen, the Amax expands better at lower velocity than those soft berger vlds.

1500fps sounds likes a good minimum impact velocity for the Amax, testing it is the only way to find out.

Good luck.
