It sounds like a pretty good caliber. I recently bought a new Winchester Model 70 Supergrade with a really beautiful curly maple stock in .264 Winchester. I actually bought a pair of them....they were the special edition guns from year or two ago when Winchester did a run of Super Grades with "exhibition" grade curly maple stocks. Dealer had a .270 and a .264 and I couldn't decide between them. So I made him an offer about $300 less than the sum he was asking for both. He accepted. So I became the happy owner of two beautiful curly maple stocked Winchesters. As much as me and Jack love the .270, it has proved a jinx and I only see mommies and babies whitetails when I take it into the woods. I took the .264 out, though, and a beautiful big buck came out. The .264 hammered him. Dropped in his tracks. It drops them just like my .270 Weatherby, and I've only ever had one deer take one step after being hit by that. From what I've read, this 6.5 RPM is a little slower than the .264, but it's still pretty fast. And it's available in very lightweight rifles. I have a Weatherby Ultra Light Weight in .30-06 and it's about 7.5 pounds with the Zeiss scope and full of ammo. The Model 70 is not a light weight but rather a full size rifle....though not nearly as heavy as my .375 Weatherby that I built. I actually prefer the normal weight rifle to the super light ones. I think they hold steadier. Anyway, I have come to love the .264 Winchester, even if my grumpy old dad says it offers nothing over the .270. I think he's wrong. You just have to load it properly. Anyway, if I didn't have a 6.5/.264 and fancied a 6.5 RPM, I wouldn't be ashamed at all. Now the 6.5/300....that one will smoke my Winnie. I'd look hard at that one. Although, they say the Winnie is a "barrel burner".....then the 6.5/300 must be a barrel melter
