They will all work fine, but I would really think looking at a heavier bullet, given your shooting range of 99% less than 100 yards would be an interesting and justified choice.

I've had some of the same experience as you with the .270. The normal (if there is such a thing) white tail bullet for this gun seems to be 130 grain. I've shot heavier .270 bullets, actually round nose bullets, and have had very good performance, IMO better performance than the 130 grain. But then I know I can not shoot a 150 Grain Round nose as far as the 130 Grain SP bullet. Example would be I may shoot the 130 grain out to 300 yards, but only shoot the 150 grain RN out to 225 yds or so.

Since your range is 100 yards or less, you could shoot a much heavier bullet, aim where you intend to hit, and increase the energy at target. Some high velocities at short ranges also result in bullet failure, but I don't think you will have that experience with the 06 in 150 or higher bullets. I would suggest a 180 grain bullet for the ranges given. But then like I said to start, they will all work fine.
