lone star , sure there have been improvements no doubt , but like everything in life some new bullets were good , some hype !
as far as hunting changing , i don't think so ! i think the gun press has conditioned us to NEED the next new product and with out reason elevate the critter we hunt to a higher level of ability to justify the purchase ! ( it may work on your wife , and i may use it , but its a dog and pony show at best ) ! i feel we today don't wish to hunt as much as we want to shoot , that fine ! but the hunting has not changed , the tools have and the way we hunt has ! we seem to picture that " out west hunt with the need to shoot 600 yard shots , 50 years ago it could be done , but 50 years ago most enjoyed the 2 week hunt ! with todays demands and cost of a hunt , many hunters feel the need to push the shot or they will have spent alot of $$$$ for no return ! alot can make the shot so i see no problem other than our insistence on not calling it like it is a choice on our part as to how we hunt !
now , magnums ! i for one think most have no idea what they are or what they are supposed to do !
some say long range , a .458 win. mag is used at a 100 yards or less - made to penetrate !
a .375 H&H mag can penetrate up close on dangerous game but also with the right load can go the distance .
some say it has to have a belt ! some say it has to up the performance of an existing round , say the .300 win. mag. over the 30-06 , if that was true then the 30-06 should be a mag. as it improved the 30-03 round !
so in reality today magnum is of little importance as a description of a rifle little more than hype !
to put this in perspective - a 2506 and a 2506 short mag . have the same ballistics , i have a box stock rem. 700 - 2506 that is 25 years old that will put my hand loads in a 1/2 inch group at 100 yards all day long , telling me the short mag. is more accurate is pure BS ! to be honest i hunt with at least 6 men with 2506's and all shoot great , i have one buddy with a 2506 short mag. and it shoots good also , but his cost per shot is more with factory loads ! yet compare the 243 vs 243SM and its a different story ! all i can say is pick the rifle / bullet combo that will get the job done and forget the BS !
