antlers are pretty tough. i've shot through them, on mule deer anyway, and not broke them off. just punched a hole in it. again tho, real heavy antler. even found a shed with a bullet hole through it once. the 2 coues that i saw stop bullets were both broadside running and both spun about 180 degrees when the bullet hit. i imagine a lot of the energy was spent in the whiplash. the one hit by the .30/30 was doa. never even wiggled again. the one hit with the .350 was right at 200 yards. normally, i would think most rifles would tear a deers head about off. and once again, i don't dislike the .350. but i do think a bullet that big needs more punch behind it. ballistics are nearly identical to the .35 whelen. the old .348 winchester is close too. and no, i don't wanna sell the 600. it's the only one i've ever seen like it. guess it's a bdl. has a laminated walnut stock, not hardwood/walnut like some i've seen, real nice blueing, vent rib, cut checkering, black tip on the the stock, factory kick pad and a hinged floor plate to drop the shells out. most 600's are sorta cheesy. i have a couple .243 mohawks. real rough finish on the exterior metal. hardwood stocks. blue is like flat black spray paint. plastic trigger guard/floor plate. good shooters. my kids killed a couple dozen deer with them when they were young.
