Freddy--you are absolutely correct about a few fps don't mean much for hunting. I had just picked up in several of your posts that you were wanting a bit more vel and I think you have a bit of room to go with the re17.
I have a tikka in 300 win mag that shoots 180's at 300 yds into groups that would make the average guy happy at 100 but it does so at about 2975 fps. The gun has freebore and I think it could easily do another 100 fps if pushed but there isn't really any point.
I have read there are some newer high energy slow powders coming down the pike for calibers like the rum and 30-378. So, all this pushing with re17 is just the begining. It will be interesting when someone gets a pressure gauge hooked up to some of the calibers we all shoot and compare the high energy stuff to our good old powders that have been around for a while.
