Re: Any of you have a Sig 522
I love mine as well, its basically the only .22lr I shoot these days. Personally, I have more fun with it than my Volquartsen barreled Remington that I may end up selling down the road.
One thing to note is the stock is a little low and cheaply made so with optics mounted you're going to have to use a chin weld. I saw a guy at the range who bought a metal adapter and replaced the original stock with a Magpul PRS which gave a better cheek weld.
At 300 meters most of my shots using cci minimag are hits on a 12" plate. I have a SWAT edition as well but feel it is a bit front heavy.
Overall the rifle is excellent. It eats every type of ammo, even cycling subsonics like Wolf MT and Eley CS. The only time I had a misfeed was due to sheer gunk buildup from over 500 rounds fired without cleaning.
