a .243 is great for mule deer out to three hundred yards. but the bullets have to be light and have good penetration and seldom do you find this combination. I would most definatly hunt with the 7mm. If you hand load try a light charge and persay a 139 sst from hornaday. now a gun is a gun and they only do there job when used properly. the reason the sst are good is because you can make a shoulder shot and still get good penetration so at ranges like that your not really gonna wanna track a deer even farther so a shoulder shot should be a consideration.
nothing against a .223 but it should be noted that most states have a min. of .24 cal for centerfire rifles used to take Deer and similar size game animals. Check your local regulations before using a small calibre rifle for Deer.
Fuzzybear; I use a 22-250 for deer here in North Carolina. It’s legal and deadly. The combined technology 50-grain bullet with H 380 powder is a great combination. I always get pass-through shots no matter where it hits. Also remember we use dogs to “move” the deer down here. I have yet to loose one or have one to run more than 50 yards. The largest deer I have taken with this rifle / bullet combination is 203 LB’s (on Foot).
I owned a 243 win for many years and was always going to try the 80gr core locks. Being satified with the 270 win and 130's, I never attempted it. But then again, all of my hunting has been in the vast western states.
I have a friend who loves to use deer feeders that will hold like 5- 40 pound bags of feed or corn, and wants help hauling them deep into the woods where he has amazingly located the perfect spot for this 30 pound battery operated tripod that will only be there for a couple of weeks each year. My suggestion to him was to build some kind of light weight gravity feeder that could be strapped to a tree or a fence post if permenant, and this is what we came up with. I am...
