Don't know about SST's but don't buy their
Stalker Xtreme's I did what a bunch of junk.
Broke or cracked every one of them and never got to hunting. They hit target and wiggle
And thats it . And yes they were hitting straight.I thought meybe they weren't so I checked with a paper tune.
Guess you get what you pay for.

Hunting is nature.
It is our nature to hunt.
I'm not a hunting fanatic just a hunting addict.
