    I guess that I won't be much help, but I'll talk some......

    I too have much interest in this cartridge. Especially since Remington has been making the Sendero SFII in the .264 Win Mag.

    I know a guy that has a .264 Win Mag in a Pre-64 Model 70. He swears by his and has harvested many deer and Elk with it. I know he likes 140g Bullets and uses IMR 4831.

    He's an older Feller and hasn't or rather isn't the type to use those "new Fangled......Bullets" So I know he wouldn't be much help.

    there is obviously something good about this cartridge if it's being chambered again especially if The Sendero is one of them. I personally belive that the .264 Win Mag is severely under rated.

    I bought a new Remington CDL in 264 and worked up some quick loads last fall. 60 grains of Re 22 in Winchester cases with Fed 215 Primers and 130 gr Accubonds. Also loaded up some 140 gr SMK's with 58 grains of RE 22 in the same cases and primers. Both shot an inch or less at 100 yards. I also would like some one to post some pet loads for this caliber. I'll be working on some loads for this gun and a pre 64 Westerner that I picked up last summer when the weather gets a little better.

    Yes, this cartridge should be way more popular! The average guy doesn't buy it because you can't find them on the shelf like a 7mm rem mag etc. so they don't buy it. I can get over 3300 fps with the 140 Berger out of mine at .640 BC. Run that through your ballistics program and compare it to say a 7mm rem mag, 300 win mag, etc, and tell me why this rifle isn't way more popular. My most accurate loads to get more than 3-4 shots out of the brass run in the mid 3200's. 67 grains of 7828 puts mine over 3300 fps and is very accurate. 7828 along with magpro and even H-870 gives very good results with the 140 grain. Some of the best loads with all the slow burning powders require a ten foot drop tube and 5 minutes of tapping to get enough charge in there but they shoot really good with the 140. 77 grains of H-870 in mine will get into the 3320's.

    Those are some hot loads! The Nosler manual shows 61 grains of 7828 with a 130 grain bullet as max. I wasn't really showing pressure signs with my loads but my groups were starting to open up. I loaded some 140 gr Bergers with 58 grains of Re 22 and had 3 you could cover with a dime and the other 2 opened it up to about 7/8 of an inch at 100 yards. I'm going to play with seating depth and powder charge and see if I can increase both accuracy and velocity, just haven't had time yet.

    Maybe I have a super hot barrel. I wouldn't know because this is the only one I have to play with and worked up loads on. It is a Douglass xx premium about 25 years old with a 1-8 or 9 twist. Some barrels shoot faster than others depending on numerous things. While I have some loads sitting here beside me look at this pet load for my 300 wby. 200 grain accubond at 3219 fps with 87.5 grains of I-7828. 180 AB at 3414 with 90 grains of I 7828. Who needs an ultramag? This is the only 300 wby I have ever owned that will shoot these but this one is a hot barrel. My loading data is way more extensive than the loading manuals since I have kept records for 35 years building rifles. Just work up for your rifle and see where it goes and never under any circumstances start out with another guys max load! What do you guys get for velocity in your 264 winnys?

    Nosler lists max for the 300 Weatherby with a 180 grain bullet at 84.5 grains of 7828 and 83 grains max for the 200 grain with the same powder. The chronograph that I used was acting up the day I was trying to get readings on my 264 loads but the 130 grain Accubond was around 3100 fps and the 140 grain Berger was around 3050, quite a bit lower velocities than what you are seeing.

    Those are very light loads you are quoting out of the nosler manual. These manuals are good to give you starting data. But then you find what your individual gun will do. After you brought this up I went down and found my speer loading manual of the time when I was working up loads for my 264. This was propably my reference at the time. Here are the loads straight out of my speer manual and it looks like my gun shoots right in there with the gun they used for there loads. Here are the best loads for the 140 grain bullet. 64 grains 4831 at 3267 fps, 76 grains of H-870 at 3293 fps, 75 grains of H-570 at 3313 fps, I was one grain higher on the H-870 and the 7828 load is right in there with the 4831 since there is roughly three grains difference between the burn rates. H-570 they don't make any more but my loads with retumbo and magpro would translate right in there. The accuracy load that shoots great in virtually every 300 wby I have built for years is 86.5 grains of 7828 with the 180. It is not a super hot load in most rifles and sends the 180 at just 0ver 3300 fps. 83.5 grains 7828 is the accuracy load for the 200 accubond in most rifles and that runs a tad over 3100 fps. My super hot 300 wby barrel just does a bit more than the others and you run across those every now and then when you build a bunch of rifles. I have been working quite a bit with the 300 wsm lately developing loads and my best velocity/accuracy combo was 72 grains of H-414 with a 150 grain bullet at 3419 fps. I shot it well to 74 grains but the accuracy went away. If you compare those to your nosler manual I bet those are above there listed loads also but they are very safe with no pressure signs in the gun I am testing. In the 264-300 short mag I am testing I am getting the 140 between 3100-3200 so far with no pressure signs. Your 264 winny should easily get into this velocity range if it is a 26" barrel. Good luck with your load developement. I hope this helps to show you where some 264's will go. Like I said I only have one and that is a caliber that just isn't that popular so I haven't got extensive data from customers guns on this caliber like I do in others. So I wouldn't know if this is way outside the norm or not but I am right in there according to my speer manual.

    I forgot to add that I have a side note by the 264 data in the speer manual. I wrote 69 grains I-7828 with 120 nosler BT super accuracy load one hole group. When I do that it usually means that one is a top shooter. I had 3518 fps written beside it as the velocity.

    The 140 grain 264 is 3.335 OAL. I need to clarify that earlier post where I said those are light loads in the nosler manual. I was referring to the 264 loads. Those 300 wby loads are right in there with my accuracy loads. The 180 and 200 accuracy loads I mentioned for the 300 wby are max with cci 250 primers and were worked up to in each gun. Don't just throw that charge in a new 300 without working up. But most will shoot those well if the rifle has the wby freebore.

    I looked up 140 grain loads in the Lyman manual and it listed 7828 at 60.5 grains max, the Hornady manual lists 61.8 grains of 7828 as max. Nosler doesn't list 7828 as a powder to use in their manual for a 140 grain bullet. I've been reloading long enough to know that some guns can handle higher charges of powder than others. One of the early Speer manuals from the 60's was quite hot, some people were blowing primers with the max loads listed' newer Speer manuals are fairly conservative. I will work up my loads slowly watching for pressure signs and watching my accuracy as I go.
    A friend of my dads when I was growing up in the 60's, who was also a part time gunsmith, had a 264 mag and I have always been fascinated with them. Thanks for the info on your gun, and loads, it seems like it can handle extremelly hot loads with ease, and the velocities are also very fast accordingly.
