17hmr vs 22 mag v-max vs v-max

For the most part those are pretty standard results.

Having shot sage rats for most of my life with a variety of different rimfires from 22LR to 17WSM the 22mag is always the worst with regard to ricochets and I'm sure it's largely to do with the fact the bullets don't come apart like they do in the 17's, instead they skip and ricochet.
 
Good video man! But I would definitely question the stated velocity of both rnds.. The 22 mag has a larger expansion cavity its just a little deeper due mostly to the bullet weight/energy.. I doubt either cartridge is getting the claimed 100 yrd velocity due to BC.
 
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.



 
To clarify my statement.. The only way to know the true velocity from any given rifle (due to several factors actually) is to test tthe velocity at muzzle & at 100 yrds or whatever distance.. Then, with the results, you can figure the BC your getting.. The mag if loaded to full potential, can be quite devastating with the right bullet! also much more accurate than people think... But as the bullet slows, so does the twist! which in turn changes the BC which also effects terminal performance at further distances..
 
Just a guy in your back yard is right.

Set it up so they are doing the same velocity at impact If all you want is a expansion test.
For no expansion the 22 mag sure had a much nastier wound cavity and a bunch of penetration.

15" of penetration is great - if you're shooting a target thats 15" thick. which really isnt the designed wheelhouse of rimfires.

if you look - the wound channel on the 22 mag doesnt start until around 3.5-3.75" mark. so on a relatively small target - squirrel, cottontail, groundhog, etc... the bullet isnt starting to do anything until after or almost at exit - assuming a broadside heart/lung type shot. otherwise its an ice-pick wound until after its past the vitals.


whereas that vmax starts its wound channel about 1" in... and dumps everything in just over 6" - leaving a jelly mess in its wake.



the point is - the hmr vmax running hot like it does puts the wound channel where it matters for small critters - starting just inside the skin layer with disruption in the body cavity where it belongs.
 
Add bone and things that are in a living target and you'll see different results. I've recovered .22mag bullets or fragments from animals and haven't ever seen one not work like it's supposed to.

Put bone in front of that frangible 17 grain bullet and you'll have wounded animals if you're shooting anything the size of a house cat or bigger.
