Now I am new to all of this, as far as hunting would go and what to use, on what animal. What I am trying to understand is this: Why is the 44 mag considered great for big game, while the 30-30 is advertised for medium game, yet the guy at my local gun store warned against using anything less that a 308 for even that. For me, the self admitted newbie that I am, I see that the 30-30 moves faster, apparently can reach out farther, and has more energy than the 44 rem, and while the 30-30 does not seem to hold a candle to the 308. So is it the bullet weight that makes the 44 so much better for game than the 30-30? Is it the speed and force that makes the 308 better for deer? I know this sounds silly but I had been kicking around the idea to try to go for deer and the guy behind the counter filled my head with doubt about the dependability of my old inherited 30-30 for clean kills. The internet says the 30-30 is great for deer... I just want to understand what the fuss is about... or if this guy was just trying to make me nervous and get me to buy a new rifle. Sorry for the rant! I hope it makes sense what I am trying to ask. I appreciate any info you all might share! Thank you.
