Nice setup and writeup. If you have a chance, give some of the lighter pellets a try like the RWS Basics, PistolMeisters(SP?), R10's and JSB Exact RS 7.3 grains.Off of a rest you should be able to literally stack pellets all day long. Have fun and good shooting.
My bench rest/thingy is a folded and rolled up bath towel with a couple of tightly tied strings to keep it sort of round and kind of firm. Works great!LOL!
SNOW! Hmmm... Snow shoes or a tobogan comes to mind - LOL! Any chance you could set up a range in your barn or shoot out of a door or window? It would make for a more comfortable shooting experience. I vaguely remember snow from my early days in WI. Brrrrr!!!!!
This is for Joe in reference to his question concerning the "cant" on the trigger of the IZH.
