Downshift, Very interesting idea. I've never really considered that. I did a bunch of science fair projects w/ my son where we chronographed bullet penetration vs velocity w/ Nosler BT bullets shot in a 308 Win. If you have problems getting ballistic gel, you could instead use water soaked bundles of newspaper. One thing I know you'll find is that when shooting an expanding hunting bullet like the NBT (w/ the bullet weight constant) penetration will decrease as velocity increases. I remember the 125 NBT penetrated as much as 14" @ muzzle velocity of 2200 fps, but only 10" @ mv of 2650 fps.

If you handload or know someone who does, you could always load the muzzle velocity down so that you could shoot the target at 10 feet instead of 100 yards. For example if the bullet is velocity at 100 yards is 2700 fps, reduce the load so that your test round muzzle velocity is 2700 fps, then shoot the target at close range (10-15 feet or so).

I'm not sure if its a valid theory or not. A deer can only provide so much resistance, and resistance is what allows the bullet to transfer energy, so it seems to me like there would be an asymptote if you plotted the amount of energy left in the target for each caliber. At least that's what it's seemed like in my head on plenty of cold mornings

Like I said earlier, there definitely seems to be some tapering off of the amount of damage done by regular hunting loads after the .30-06 and into the belted mags.

After I went to bed last night I started thinking that wet news paper might be a good idea, but it might invalidate my results a little bit because it's "less professional." It's certainly an option though.

I have access to a very large cooler to make plenty of gel, so I don't think that would be too bad.

I have a buddy who hand loads. One thought was to get him to load me a bunch of 150gr .308 loads from pipsqueak to barrel peeling.

Its still very much on the drawing board and not close to happening. Hopefully myth busters reads this and does it for me
