well last winter I was shooting a Remington Model 700 chambered in 243 Winchester, and will most likely do so again for 2008. It has a 24" stainless barrel, and for most of last winter I was running a laminated stock on it, but just before spring I switched to a snow camo Bell & Carlson Medalist fiberglass stock, which is real nice. I was shooting 70 grain Nosler Ballistic Tips @ 3500 f/s which worked real well on the five coyotes I shot with that rifle, at ranges out to 300 yards. This coming winter I may try something else, summer load development will start soon with the light 55 grain Nosler BT, which in inital tests seems like it should be accurate and give a velocity of around 3850 f/s, although I've pushed them up to 3970 f/s but accuracy went south. Topped with a Leupold 3-9x40 VXII with the LR duplex. I put a 2.5" sunshade on it to cut the glare off the snow and to give me cool sniper look.
For calls, the past two years I have enjoyed using a Foxpro Fx3, but I sold that last month to a buddy and before December I'll most likely upgrade to the Fx5. Teamed with the Jack In the Box decoy, its can be a very deadly combo. Used to use mouth calls for a few years and had good results with them, but I do prefer to hunt with the electronic caller.
I've found early morning through late morning the most productive time for calling, but any time you can get out and hunt is good. I havent had much luck in high winds, or warm weather.
For camo last winter I used a Cabela's coverup parka, in Prairie Ghost snow camo. Its a good pattern. This winter I might pick up some Columbia wool in a greyish pattern that will work in both fall and winter. Lately Ive been wearing some snow camo fleece pants, Mossy Oak Tree Stand I believe is the pattern. Im usually sittin down anyways so its not too critical. Speaking of sitting down, a good waterproof foam cushion is an excellent thing to bring along.
