wow, what an interesting topic to comment on for my first post. First off: credentials. I bought a mini 14 ranch that was originally a police dept gun for $400. Since then, the only problems i have had were crap magazines (of course), reloading (brass problems: mis-shaped shoulder from brass out of my dad's mini 14), and the scope i put on it (never buy millet). Now, as far as carbines go, i have read a bit and i picked one up once (cool, huh). I consider myself impartial to opinion and base what I think and say on logic and scrutiny of ze facts.
My questions are these:
1. what are you using it for? killing running rabbits at 10-200 yards id say mini14, tested and proven over the heavier carbine. Ballistically, .223 has the advantage as a larger diameter bullet is not necesary. Is it for Home defence?? Lord, i pray im not your neighbor when you light up an intruder. Try a shotgun or possibly a pistol for the house to save collateral damage. Plinking(cantalope)/shooting pictures of Hilary Clinton at the range? Either is a good choice, though if i went tomorrow and had a choice, i'd choose the carbine as ive never shot one and its a cool old gun.
2. Whats your price range?? I don't know what carbines go for "new," but a new mini is moving upwards of $6xx, more towards the AR range (ive seen em built for $750). I bought my mini used and in excelent shape for 2/3 the new price. My rifle is just as good as new and will do anything one from the store will. That being said: make sure you always always check the tell-tail signs, such as excessive wear, bore pitting, bad finish yada yada.
3. As far as ammo is concerned, thats really a question of what you are using it for. You want to know about hollow points? I dont think a pumpkin will feel differently if you shoot it with a HP or a FMJ. Shooting small furry things? HP definetly preferred for .22 LR, but this is a 30 caliber cartridge designed for people killin. Remember, this is a war gun (albeit a light model). .30 carbine shells got plenty of poop for small critters, and possibly up to antelope sized game. I'm not sure how .223 and .30 carb compare, but .223 is capable of taking deer sized game (seen it done). If you're looking to defend yourself at home, once again shotgun is the preferred short-range weapon, but it is a free country.
Closing statement: Opinions are like a**h*l*s, everyone has one and they all stink. If you buy a carbine and like it, great. if you buy a mini 14 and like it, also great. If you think one is better than the other, well maybe it is for you and what you were using it for. In a perfect world, you would buy both and a ton of ammo, shoot until your shoulder bleeds, then decide which is best for what application.
EDIT: as far as accuracy goes on the mini: it is true, not a target rifle. Wasn't made to be. Its a truck gun that sits in the rack collecting grime dust and goo, until the unsuspecting coyote is caught by suprise, or yonder jack rabbit ventures too close. Why do they make 20-30 round clips? Because if at first you dont succeed, try try try again. Besides, youre not gonna use it for a biathalon are you?
