I’ve tested 7 powders in the .264 with 140gr bullets.
Use the slowest burn rate powders available for top speeds.
Some of the replies are amusing

It's pretty typical to get 3100 fps from a 22 inch 270 with 130 gr bullets.
Compared to a 264 which, with careful load development, will make 3200 fps with 140 gr bullets from a 26 inch barrel. Which is actually pretty comparable performance.
But I have never owned a 270, and do not plan on buying one. I have worn out one 264 barrel. That Winchester now has a 27 inch PacNor barrel in 264. It makes 3300 fps with a 130 gr Acccubond over 71 gr Magnum. That barrel is heavy profile, and not much for packing.
So, I am now in the process of rebarreling a Win 70 classic to 264 with a standard Magnum barrel profile. It will probably also be 27 inch.
But yes, five inches of barrel, an extra 10 grains of powder, one less round in the mag, to beat the 270 by 200 fps. According to Charlie's post, 125 fps is due just to the extra barrel length.
Was this stuff supposed to make any sense?

Remington's 264's were all 24", I think. So that's what I had. If I were to build a rifle or have one built for me, it would have a 26" barrel. I sort of need a 264...
Not to hijack the thread, but did the 264 have the same issue with pressure deviations that the 7RM has? I recorded extreme pressure/velocity excursions with 140 gr partitions and the first lots of RL25. On three different occasions I recorded velocity increases of 250 to 300 fps difference between 1'st, 2'nd, and 3'rd shots in a string with a blown primer on the third on one occasion. The temp was over 100, I attributed the increasing pressure to increasing barrel temps with subsequent shots, combined with the long bearing surface of the 140 gr partition. I was never able to safely load that bullet over 3000 fps with any of the powders available at that time. I have never experienced any issues with boat tail bullets combined with a long ogive and short bearing surface. My rifle loved the 140 gr Sierra spitzer boat tail over H 1000. Today, the choice is far better in powders and in bullets.

I would have to recommend at least a 24" if you cannot have one longer because that's a lot of powder to burn in a pretty slender tube.
I have a Belgian Browning Safari Grade (Mauser) .264 and cannot believe Browning put the 22" barrel on it. It's a family legacy gun, so not going anywhere. I doubt it's had more than ten boxes of ammo shot in it since new so I am hard-pressed to justify re-barreling with so little mileage on this one. And if I were to re-barrel it, it just might end up with a .284 bore anyway. It IS an exceptionally loud .270...but I can tell you the few 140 grain factory Power Point and Core-Lokt bullets we have ever managed to recover from game usually have long shanks behind the mushrooms, having penetrated the full body length of a whitetail deer.. With cup and core bullets, it kills the old-fashioned way, with sectional density and penetration. This is where it may have a slight edge on the .270 with 130 gr. bullets, which are much shorter proportionally and absolutely. With a similarly mushroomed front, the 130 gr. .270 bullet just won't have as much shank intact to continue penetration.
And it may not matter in practical terms, sort of like debating how many angels can dance on the head of a pin.
I tried to handload for it once in the 70s with 140 gr. Sierra Spitzers, and they had to be seated painfully deep in the case to clear the throat. I used Hodgdon 4831 (the original recovered milsurp powder) thinking it might be slow enough to work in the .264. About half of the bullet was below the neck of the case and they made discouraging patterns, not groups. It was my grandfather's gun at the time and he didn't shoot it more than at a couple of deer a year, so he just stayed with factory ammo and I went back to having fun with my .243 and 30-06 handloads.
Someday when I am really bored, I may see what it will do with a different bullet shape, such as some 140 gr. Remingtons I have. They are .257 diameter forward of the cannelure and .264 behind the cannelure. They may resolve the seating depth issue.

As any shooter knows, there's a bit of difference. But not as pronounced with common hunting bullets as some might have one believe.
If you want to talk of specialized LR bullets, the Berger 270 caliber 170 grain EOL Elite Hunter is stated to have a BC over .700 above 3000 fps. Of course no 270 Win can push it that fast. And it takes an eight twist barrel.

I had that issue with RL-25, too in my 264WM . How ever in my 6.5-06 it behaved itself. My 6.5-06 is slow, max is 2850 where as my 264WM load is 3150. 140s

Some of the replies are amusing Have tried more than 7 powders in the .264, but that's going back around 20 years. At that time Magnum was new, and still haven't found a significantly better powder. But also tried some other 6.5 rounds. Eventually came to the conclusion that for hunting, the 26 Nosler easily gets the "original" 3200 fps with 140s with excellent accuracy--or more if you want it. Of course, the accuracy depends on the rifle.

I haven’t tried N-570 in the 264 WM but have a hunch it may be the ticket. RL-33 with the 139 Scenar was over 3200. I’m shooting the 147 ELD-M now in it at a tame 3100 with RL-33

My m700 Ltd classic has a 24" barrel like all the early 700 bdl's had. When Remington came out with the ss fluted sendero in 264 win mag they finally pulled their head out and put a 26" on it. Most all 264's had short saami spec throats because of the 2 diameter bullets that WW and RP made for them. Haven't checked any current production WW or RP factory ammo but I'd bet they are the same old 2 diameter bullets in them. Fact is Remington factory 6.5 Creedmoor uses the same bullet. Allways shot h870 and fed 215's in mine with the 140 npt to get just over 3000. Mb

When I had my 264WM rebarreled, the gunsmith throated the chamber "normal" . He said it took the qurikerness out of reolading the 264WM. He was right.

I got my .264 out to the range night before last, as a result of this thread. P64, 26" Stainless bbl with the iron coating. I put it in a McMillan, have a 4.5x14 Fullfield Burris on it, and despite being a .270 guy all the way to the bones, am just thrilled to own this rifle. Some guy here at the 'fire sold it to me, poor fella.
I'd been spending most of my rifle and reloading time pissing around with a .308 FW and a .270 FW since last year. Rounded up some .264 shells already loaded, and just went out to punch some paper. It was good to remind myself what amazing performance and tremendous accuracy that rifle gives. Might be the last rifle I'd give up. I'm a .270 guy to the core, but this rifle speaks to me. I never ever had the problems reloading that others have claimed, its not fussy at all, it just makes sub 1" groups repeatably.

My first Classic in 264 had as nice a Walnut stock as I have seen on a production rifle. Until my 12 year old son let it get between his 4-H pony and a tree. It still wears Rutland pepper plywood 30 years later.

Love my Remington 264 Win Mag Classic. One of my favorite hunting rifles. It loves both 120 gr ballistic tips and 125 gr Partitions. It’s accounted for many whitetails and antelopes and few Mule Deers too.
