I took her out on her maiden voyage today. Pretty impressed with the results seeing as these were 1.5 grains below book max.

This may have already been said, the 6.5-257 Wby Mag could have been put out by Weatherby many, many years ago and they didn't, I believe it was just another .264 Win Mag and they could not have added anything to the cartridge performance, end of the story. When they did come out into the 6.5mm game, it was based, as we all know... on the .300 Wby Mag case and it's a hot one. Go with the .264 Win Mag... it's a hick of a good 6.5 Mag. Just my 0.2 Cheers.

It’s throated to seat the 156 @ 3.550”. That puts the bullet almost perfect at the neck/shoulder junction.
That is exactly how mine is throated…..great minds and all that.

Trying to get my hands on some 150g ABLR is proving difficult. Can’t get Berger’s here anymore.

Cheers.

In my 264 WM 26" Bbl. I'm driving Nosler 140 AB's at 3229 fps. Hammer Hunter 121gr at 3450 fps, & 100gr Barnes TTSX at 3700+ fps. Not the slighest sign of over pressure in any of these loads. It's just a matter of the right powder. I'm using off the shelf Win & Rem brass. Another plus for the 264 WM is relatively inexpensive 7mag brass can also be used. A simple neck down to 264, instant 264 brass. Who knows what the further holds. Wish we were close so I could show you some of the 264 positive virtues.
I know this is an older thread, but I just ran across it. I have a pre-64 264 Win that I'm getting ready to start fooling with, can't remember if it's a 24" or 26" (aftermarket) barrel. I'm mainly interested in bullets in the 130-140 grain range (likely Ballistic Tips and Accubonds) and was wondering what powder you've had luck with in that range? I have a 300 Win that loves IMR 4350 and quite the stockpile of it, so I'm leaning that way to start with, with the current situation.

Thanks.
