Thanks for the info guys. The main reason i want a gun just for deer not just downsize the grain of bullet in my gun is cause when i go for deer i do use 150 grain Spire Tip Boat Tails but then sometimes the next day im going for moose or elk and i switch over to 180grain Partitions and i either dont have the time or sunlight to re sight my gun in according to the bullet or i just down right forget too so thats why i want a gun just for the deer.But thanks for the info and by the sounds of it i may go with the .270 or even .243 but i do value my hearing so i think ill pass on the BOSS.
