Ripone I'm a hunter, my guns are my tools, I do love shooting them at the range, but for practice for my hunting in the field. there are many carts for varmint and big game hunting, I try to limit the amount of rifles buy using curtain carts for curtain game animals to be hunted, My 22lr's are for small varmint close range around the house, my 243 is for medium to large game coyotes up to whitetail deer/prong horn medium to long range, then my jump is to 30cals, 300 Savage/308win/ 3006 for deer/hog/caribou/elk medium to long ranges, my larger carts like my 338winmag/Marlin 450 guidegun/454 casull/44mag for medium to large game.Heavy hitting carts., I use these for Bear/Moose etc...I was never impressed with the 223 cart, just my thoughts, too light of a bullet for where I hunt,if I was to use one, wind is big factor shooting long distances, and the 223 does not do well with any wind, this is why I went with the 243win, if not that I would go with the 22-250 due to its performance and still better than the 223 in the wind. Im talking that catagory of carts, where I'm from there is many windy days in the field. So I need a cart that can harness a good size bullet and maintain in the wind, I found that 100gr bt Hornady interlock fits the bill, affordable and well Field tested. One day at the range at 150yards I shot clover leaf and the wind was gusting at least 20 miles hour across the range, this impressed me greatly, I have tried shooting the 223 on windy days and found little accuracy using various bullets, this was a friends 223, I was reloading for him at the time, he ended up getting rid of it for a 243win;)So if the wind is not a problem where you are the 223 will work fine on yotes, just my thoughts, If the cart fits the job at hand, use it, if it works well, stay with it. Different strokes for different folks. Aim small hit small. RAMbo.
