I have some, but have not hunted with them. I was at the range the other day with the Genesis, working up a load for this weekend. I was shooting the 245 grain Powerbelt, and decided real quick that that was going to be my hunting load. When I was all done, I loaded up 80 grains of 777 powder, and a 270 Platinum, and shot a couple of shots. Now, I didnt spend much time with the 270's, ( there were a lot of guys waiting for my spot at the bench) 2 shots, the first one was about 8" to the left, and the second shot was about 8" to the right. I plan on working with the 270's more when I have time.
On a side note, I thought that the Platinums could handle the hevier loads?
