Actually it does. Remember .22 LR bullets are soft lead so they expand pretty easily. In fact subsonics work better than the high velocity stuff cause the bullets don't fragment as easily. Having said that I use high vel ammo for hunting because it carries energy further downrange than subsonics and Alberta is one big fricken range.
I shot a bunch of different stuff into wet newspaper and learned the following:
SSS penetrates very well but doesn't expand at all.
Conventional subsonics penetrate about half the distance of SSS but expand on average to .36".
High vel ammo penetrates almost as far as the SSS and expands to almost .30" diameter but tends to fragment. My testing showed a 25% loss of weight.
Keep in mind these tests were done at point blank range. Impacts at distance will alter the results.
I think you are quite right. I read an article where SSS was being used to kill deer at 100 yds. Now that requires a CNS shot but no conventional .22 rimfire ammo is going to be able to do that.
Dude, I am hardly an expert in this. I just made the effort to actually set up some type of quantifiable and repeatable test for comparison of different bullets. Saves me talking out my ass about something I don't know anything about.
