Compared to the venerable .300 Winchester Magnum's most common load - a 190-grain Sierra MatchKing at 2900 fps - the .260 has about 17% less wind drift and a few clicks less drop. Even though it shoots a 140-grain bullet, it still has 87% of the Magnum's energy at 1000 yards because its slim design yields a much higher ballistic coefficient (BC) value, so it retrains velocity longer. It also has 60% less recoil than the 300.
One of many cartridges that do the same thing.
nobody is claiming the 260 is a bigger hammer than a 300 Win Mag on big game, just that it is often compared to the external flight characteristics (drift/drop) of a 300 Win Mag w/ 190gr Sierra HPBT @ 2900 fps, when the 260 is loaded with a 142gr Sierra HPBT @ 2800 fps (which is easily doable with a 26" target barrel)
All I'm sayin is if a comparison is done fairly the balistics are not the same. If you use handloads and a 26 inch barrel in both calibers the 260 is going 2800fps and the 300 would be going 3200. This makes for a big difference.
To me it's like saying my 302 motor will match your 351 motor in performance, but I get to build mine and yours remains factory.

But it's not if you consider BC. In order to get the sam BC of 140 grn .264 bullet in a 30 cal bullet, you have to step up to 180-190 grn bullet.
358BLR, I've tried the 129gr SST and couldn't get them to group as well as the 120gr Nosler BT or 130gr Accubond etc. I wanted them to work, because they're pretty inexpensive and they have a high BC, and look to be a good deer bullet.
I had a 260 rem in a 700 mountain rifle. I wish I never sold it. I would highly recommend the 260 rem.
