+1 for cove creek. Bob and Bobby are great.
The 257 Weatherby is a .25 caliber, (6.35 mm), not a 6.5 mm. The 6.5 is a .264 caliber. Not that the 257 Weatherby is less efficient, with its speed it's generally as efficient as most 6.5s but it's a smaller caliber.I've owned a 375H&H Blaser R8 with the 22mm safari barrel...rifle weight was over 13#, and was way too heavy of a rifle for that caliber. I now shoot a 375H&H with a 17mm standard barrel, alloy receiver and no kickstop that weighs right at 10# including scope, sling and ammo. Bare rifle weighs 7.75# and is still a pleasure to shoot. I'd highly recommend staying with the 17mm standard barrel for 375 and below. If you need to add weight, add the kickstop because you can easily take it out. For a rifle that is being carried much more than it's being shot, it's something to consider.
As for calibers...if you are looking for 375H&H and 300WM it would be wise to stay in the same Magnum (MA) category of bolt heads. Something like the 257WBY would be a nice 6.5mm to add to the collection and uses the same MA bolt head.
I understand that I was off 0.15mm, but I should have been more clear. The idea was to get as close to a 6.5mm and still use the MA bolt head. The 257WBY is as close as it gets.The 257 Weatherby is a .25 caliber, (6.35 mm), not a 6.5 mm. The 6.5 is a .264 caliber.

The 264 Winchester Magnum is actually as close as it gets or the 6.5x300 Weatherby. There are no flies on the 257 Weatherby but it is not "as close as it gets".I understand that I was off 0.15mm, but I should have been more clear.

It's as close as it gets with factory chamberings in the rifle being discussed - Blaser R8.The 264 Winchester Magnum is actually as close as it gets or the 6.5x300 Weatherby. There are no flies on the 257 Weatherby but it is not "as close as it gets".
I see your passion, but I must say...you have a peculiar way of trying to influence people. Good luck with that.Your reasoning isn't on topic. It's the same meandering that the author of this thread had about the reason why the Germans invented the CRF. Nothing to do with reality. The Mauser was not a "peasants" rifle. It was sold to governments and their military. Same uninformed idea that a 22 mm barrel can fit into a standard Blaser action, then surprise...The author bought an action that could accomodate that barrel. A second action after praising wrongly the vast peripheral virtues of the standard action capable to accomodate anything. Man, just stay on topic. I don't enjoy uninformed banter for the sake of it. You wont get another reply.
You're trying to be a white knight for someone as uninformed as you are confused.

Would you be able to expand on the above?The 257 Weatherby is a .25 caliber, (6.35 mm), not a 6.5 mm. The 6.5 is a .264 caliber. Not that the 257 Weatherby is less efficient, with its speed it's generally as efficient as most 6.5s but it's a smaller caliber.
There's a misunderstanding. While (almost) every metric calibre is rated by the lands' diameter the imperial approach is rating the calibre by the grooves' diameter. That's the reason why both dimensions usually don't match. One of the few exceptions is the 9,3 calibre group.Would you be able to expand on the above?
From what I can gather the .264 caliber is in fact a 6.7mm and the .257 is a true 6.5mm. The 6.35mm would be a .251 caliber.
Although most cartridges named 6.5 is .264 and therefore not true 6.5mm.
Although I cannot anchor any evidence about that fact, I believe it was a strong factor when the Cape Province came out with their Ordinance of 1974 that is still in force in the Eastern Cape “… calibers above 6.5mm to be used for…” or something to that effect.
Thanks
Sorry for the off topic.

Thank you @Hunting Sailor & @Christot. I appreciate the information on lands vs diameter. I don't currently own a 257WBY but it's not for lack of wanting one. When I do, I can tell all my buddies I've joined the man-bun-club with a 6.5mm. Cheers.There's a misunderstanding.

Well, close. Transferring the .257 Wby to a metric rating it would be a 6,35mm Wby or 6,35 x 56,7 mm. If your buddies don't know the difference, yes you joint the 6,5mm club.Thank you @Hunting Sailor & @Christot. I appreciate the information on lands vs diameter.

Appreciate you too @One Day... for setting the record STRAIGHT in a way that only you can do.
