Not to sound like a jerk or anything but....... do you guys get out much?
Bruce,
Ammo for .270 is available absolutely anywhere that the 30-06 is availale. While it does not have the range of bullet weight that the 30-06 has it is pretty much a non issue considering what you will be hunting. Florida deer and hogs require either a 150 grain bullet from the 30-06 or a 130 grain bullet from the .270. That's it. Even if you were to hunt animals as large as moose you still wouldn't need a bullet heavier than 180 grains in the 30-06 and the .270 has plenty of 140 and 150 grain bullets that will kill these animals just as dead.
Mr, bow,
Neither the .270 or 30-06 are hard kickers. Especially for someone that is 6 foot tall and 200+ pounds. Someone this size should be able to sit down at the bench and shoot mulitple boxes of cartridges from either of these two with no problem. My 12 year old son, who is 5'6" tall and 120 pounds, has a 30-06 for his hunting rifle and has absolutely no problem what so ever shooting 40 rounds or so from the bench.
Now that I got that out of the way.......... Sorry guys!
Either one will do a great job at killing deer and hogs. I prefer the .270 over the 30-06 but it is all a matter of personal preferance. What one person can do with one another person can do with the other.
The biggest thing you gotta remember is you gotta practice to get good. When you go out hunging you must remember to not push your personal effective range limit. The cartridges are every bit capable enough to take deer out to 500 and 600 yards but you won't be until you put in the time at the range shooting from real hunting positions.
Good luck and welcome to the wonderful and
very addicting world of guns and big game hunting.
