As an avid fisherman for many years, I am finally getting in to deer hunting and after doing my homework, decided on a Tikka T3 Lite .270 with a Nikon Monarch 2.5-10 42mm scope. Most of my hunting will be in Florida and Georgia with an occasional trip to Texas or PA. My question is as follows, I plan on using 140 grain as my base ammo due to the SD of the bullet, but they don't come cheap as most manufacturers are making 130 and 150 grain ammo for the .270 in mass. Since the ballistics are not that much different between a 130 and a 140, can I initially use a 130 grain bullet to scope in towards 200 yds and then fine tune it with a couple of 140's? I am thinking that this will save me some $$ on ammo. Any suggestions would be welcomed.
