They stabalize in my 9.25 twist 7mm-08 so i think you should be able to with a 9.5 7mm Rem.

Re: 162 AMAX (.284) Min Expansion Velocity

Trying to vote on this one. Following the rule of thumb, wanting 800-900 ft. Lbs energy for deer. A 162 gr bullet drops to 800 ft. Lbs at 1500 fps. I have recently loaded 162 Hornady interlocks to 2800 fps using 2000 MR, Winchester brass, WLR primer. No excess pressure signs. Remington 700 varmint, 7 mm 08. 26" barrel through a CED M2 chronograph. This gives the interlock 1488 fps and 796 Ft. Lb at 1000 yards. (4700 ft elevation). The higher BC of the Amax retains 1016 Ft. Lb with a velocity of 1681 fps at 1000 yards. And some try to say 7 mm 08 isn't enough for elk.

Re: 162 AMAX (.284) Min Expansion Velocity

Back in 2012, we measured the expansion threshold of the 208 AMAX in to be 1700 ft/s in ballistic gelatin. Slower impacts reliably tumble and demonstrate excellent wounding via tumbling, but they do not expand or fragment. Our experience in deer is that hitting bone can initiate expansion or fragmenting at lower velocities than bare gelatin, but bare gelatin is representative of hitting softer locations.

Usually different caliber bullets of the same basic design and construction have comparable expansion thresholds, so 1700 ft/s is likely a good estimate for the 162 AMAX. 1800 fps gives some margin for error.

Tumbling in one caliber does not indicate a likelihood to tumble in other calibers. I also don't feel as good about the wounding potential of the shorter, thinner, lighter 162 AMAX as I feel about the 208 AMAX. High speed video shows excellent wounding potential of the 208 AMAX when it tumbles, even without expansion or fragmentation.

Bottom line is the 162 AMAX might be iffy below 1800 ft/s. If it hits something harder to initiate expansion or tumbling, you might do OK down to 1400 ft/s.

I think the bullet should be super sonic to give good results or right at super sonic so I say 1200 to 1400fps

Re: 162 AMAX (.284) Min Expansion Velocity

Ive killed deer and elk with them, furthest out to 1125 yards from a 7 RM loaded at a slow but very accurate 2900fps and theyve had no problems expanding/penetrating like any other cup and core bullet.

Average impact velocity at 1125 yards with above combo give or take etc, would be around 1450fps along with 750 ft lbs of energy.

I know its plenty and gets the job done with that bullet put in the chest cavity.
