    I own a standard 260 in a custom rifle and don't feel I need to improve it, for one fire forming brass is a pain in the ass. If I decide it needs improving I will have it reamed out to a 6.5x284, 6.5 Rem Mag or some version of the 6.5 SAUM. These are real improvements. Bolt face is not an issue as a Rem action can be modified to the larger case head.
    As far as barrels go Shilens are fine, but cut rifling barrels will last longer.

    Go with the regular 260 shoot 42 grains of H4350 and a 140 grain bullet and your ready to go hunting.

    Im going to go against the crowd on this one. I say improve it. It makes an already great cartridge an outstanding one. Fire forming is not a pain at all as you will have to do barrel break in anyways. When your done you have a broke in barrel and fire formed brass. The performance gain will put you right in the middle of 6.5-284 territory with about 10 grains less powder. I have built two of these now and both of them are giving me 2950 fps with a 140 berger while only using 44.7 grains of H4350. My 6.5-284 uses 56 grains of Retumbo achieve 2960fps with the same bullet and barrel length. Besides this the brass work in the long run is a sinch since all you have to do is neck size and load. No more trimming and chamfering for you.

    Most times, fire forming is quite accurate. so, that's not really an issue. #2,, you did say it's a hunting rifle, so round count isn't as important as a competition rifle would be. Given a choice, I'll choose a Hart barrel over a Shilen barrel every day of the week, when we're talking button rifled barrels.

    I went with a Brux cut rifled and I didnt improve mine. Only had 1 "improved" rifle here and presently its back at the gunsmiths getting rebarreled to a 280.

    The problem with improved cases in bolt action mag fed rifles is, they do not always feed correctly because there is no taper in the brass. Also a 100 fps in most cases is only one moa difference. If you want more velocity get a bigger case or buy a longer barrel. Also when you get into improved cases you reloading dies cost a lot more.
