No, it really isn't - but in the terrain that I hunt in I really do need the 300 to reach out that extra yardage. The 260 works great for me to 175 yards - but more importantly it works just as well at 10 yards when shooting a thin-skinned whitetail. The .458/300 grain Nosler is really a stronger bullet and can get in and out of a deer before it really can expand a whole lot when shot at very close ranges. After 50 yards it works just fine and past 175 it probably works better than the 260. I really so not see a lot of difference in the the .451/300 Nosler and the .458/300 Nosler - they are both Partition and they are both Protected Points... almost flat nosed. The 260 is a HP, but the nose is really well designed....

Amoung the rifles that I shoot is an Omega - it is an older one with a .502 bore so the MMP HPH-.487/.458-50 Orange sabot works very well in it. If you have a really tight bored newer Omega you may have to use the .451 Nosler.
