being a lefty myself i can tell you that either one (270 or 06) will get the job done. I have a 30-06 Left handed browning a-bolt and its on the money and puts them down if they are hit in the right spot. I just ordered (again leftys have to do it differently) a Tikka 270 for the longer distance hunts in the daytime, but i havent shot or hunted with a 270 since going after boar. Bottom line: if i had to leave the house with one, it would be the 30-06.
