i've always prefered the winchester over about anything else, that is the pre 64's and the newer "controlled round feed" copies of the pre 64. a friend bought a black shadow .243 super short and as far as i'm concerned it's junk. the cartridge is so short and fat that it absolutely will not feed without guiding it in with your left hand. the entire gun needs re-designed in order to feed that wierd built shell. and the first shot he fired out of it, with winchester factory ammo, jammed up the action. he sent it back to the factory along with the ammo and they sent it back and said the ammo was overloaded. went to the range with new ammo, stuck again. he still uses it. still doesn't feed worth a damn and still gets empties stuck. i'd pitch it if it was mine. the dealer would dang sure have it back by now. when they first started making these short and super short magnums, everyone had hell with cartridges feeding. the tikka t3 is about the only one that seemed like it was made for the short, fat ammo. i guess maybe they've worked some o' the bugs outta the system, but for me, i'd stick with the ol' standby .243 and let others worry about bugs.
