the 22 mag 30gr vmax didnt come apart because its too slow at impact velocity @ 100 yds.
if you go to hornady's website, their test data shows 24" barrel giving 2200 fps at the muzzle and 1421 @ 100 yds...
the minimum designed expansion velocity for a vmax projectile is 1600 FPS.
so even assuming its getting full listed MV - its not shocking the bullet just dumped its tip, tumbled a few times and didnt do anything else.
it worked exactly as manufactured. the vidjeo maker just doesnt understand terminal ballistics of the bullet he's testing.
put a 17 hmr thru the gel at 150 and see how it looks, or even 175 if you wanna be closer to the impact velocity of the 22 mag vmax at 100 yds. it'll do basically the same thing - ice pick, dump the tip, tumble and stop/exit depending ont he target depth.
most folks who hunts with a HMR understands that it runs under expansion velocity around 135-150 yds depending on your gun ... and we all know the closer you get to minimum with the vmax, the harder time they have expanding, if at all.
