i just bought my first rifle, a weatherby .270win, which i had topped with a leupold 3-9x40 scope. a friend of mine just told me that he is thinking about selling his marlin lever-action 30/30 which is topped with the exact same scope on my weatherby. he bought his entire set-up for about $850, but stated he would sell it to me for $500.
i enjoy shooting and have no objections expanding my small collection. however, i don't know how useful the 30/30 would be for me. i bought my .270 intending to hunt pig and deer, with thoughts of black bear and/or elk down the road.
maybe this is a dumb question, but how much more beneficial is the 30/30 than the .270? i know that bullet weight is a factor, but is a 150-grain .270 with higher velocity and energy a better choice than a 170-grain 30/30 which is slower and has less energy? i'm new to hunting and rifle shooting, so this is all kind of a foreign language still. but in looking at ballistic charts, it seems that the .270 really outperforms the 30/30 in everything except a slightly heavier bullet.
i'd really appreciate any advice or clarification... thanks!
