Favorite Light Load: 40gr H380 with a 40gr V-max moly in WW with CCI 250. Brass lasts forever and in my bone stock M700 VS it goes 1/2". Plenty good P-dog load...
Go to www.centerfirecentral.com ...find "pet loads", you'll find a bunch for 220. Also look at accuratereloading book on this site, bunch more stuff. BA

I have found that for speed combined with accuracy that IMR 4064 works best for my 220. I have two pages of data and I have found that for Praire Dogs that I like NBT 55gr. Molly Coated with 40.5gr of 4064 @ 4025 fps with .20 (5)shot groups (using fed match primers 210M). TAKE HEED THIS IS A VERY HOT LOAD YOU SHOULD START 36GR. AND WORK UP TILL YOU GET PRESSURE. I have blown primers at 41gr. on brass that had been loaded twice. But shot a 5 shot group of .018 with "New Brass" at that load! at a speed of 4060fps.
