264 win mag and 7828, 140g bullets

Hey guys,

I am curious about something. I did a tiny bit of loading this morning for the 264, I had some 7828 in the drawer, brand new, I could only figure I had bought for the 264. I searched here and sure enough there were a lot of guys using it (it seemed like) and I know I would have searched here before buying supplies.

What I"m wondering about is the manual shows I think a max of 61, I started with 57.5, but I see guys here using more than 61. is this from another manual or they worked up past listed max?

the other thing I want to know is, did you guys get better accuracy as you increased the charge?

I didn't have any factory ammo to try so don't know if accuracy was the rifle or the load, but groups were over 2-3". Not bad single shots, I had bore sighted it using the collimator, so aside from a couple of inches of windage it was 2" high at 100, which is good for right now.

4831 better? I have that for my 308 norma, but if I use it for the 264 what's the 7828 good for? Smiler

Well, 7828 performed very well for me in my Sauer 200 270 Winchester with 140 gr bullets. I don't have the data in front of me but the Sauer barrels are 25.5 inches and can burn the slower powders efficiently. I don't know if it would be proportionally as effective in the 22 inch barrels most factory 270s wear.


"Experience" is the only class you take where the exam comes before the lesson.

IMR use to say 65 gr. was a max load with 140 grainers. My Hodgdon #27 also lists 65 as max, in their IMR powder section. I have used this load with 140 gr. Nosler Partitions with good accuracy and case life. It does 3100 fps in my 24" barrel. I also have a good load with IMR7828 in a 6mm Remington with 100 gr bullets.

I would say H4831 is not better in my 264. I would say slower powders are better. US869 seems to work pretty well with the 140 gr.

My M70 Supergrade loves 65g Imr 7828 and 140 Partitions. Shot a deer we named Fat Albert yesterday morning w/ it. I now have another 6.5 Partition---perfect mushroom w/ nice retained rear core---to add to my collection. Up close or out far, the Partition does it all.

Thanks guys, I knew there had to be something. I could tell from the lack of recoil that I was under factory rounds I'd shot in it before. I wonder why they backed it down so very much. I don't care about barrel life, this is a pure hunting rig (as evidenced by it's ugliness) and as soon as I get it shooting good groups that are reasonable in speed I'm only rechecking zero from time to time.

I guess with that in mind I need to move to the 130grain TSX that I bought for CA hunting, I wanted to be ready in general with the 140's for anything out of state though. (and have a lot of 140's for it!)

anybody have the load for 130's?

thanks gents.

I'm shooting 65.5 gr. IMR 7828, 130 gr TSX, win brass (neck-sized), and Fed GM215M primers at 3340 fps, no signs of pressure, but this is 2-3 gr. over book. I'm shooting the 120 TTSX with over 67 gr. 7828. Both in .264 Win.

I called Hodgdon tech support after loading so far above book values, spoke to a handloader there who shot a .264 Win, and he said he very routinely went up to 5 gr. above their published values, just watching for pressure signs. (Hodgdon owns IMR, as you know). He said they are fairly conservative, and the book used old data.

The typical precautions with using other people's data should apply here!

Aggie: how has those 130TSX and 120TTSX's performed on game? What velocity are you getting with the 120gr? FWIW, I use the 125 Partition at 3300fps, which has been great.

IMR 7828 is an excellent powder in the .264 -- for varmint weight bullets of 100 grains or so.

If you want a 140 to go at a cartridge-appropriate speed you will need to use a truly slow powder. The old H-870 and AA 8700 are good examples. I personally use some WC-872 surplus powder with 140's, but such powders can vary from lot to lot, so I hesitate to name a charge weight. I am told that US-869 is somewhat faster than WC-872, but it might be a candidate.

Olarmy,

I almost don't want to say how fast the 120's are going because I'll get all sorts of disbelieving feedback, but here goes: Oehler chrono has clocked them on 4 occasions at 3474-3481 fps, with SD of 9 fps. Krieger 26", 1-9" bbl. Shoots 5 shots consistently into .76", usually 3 touching, 2 spread out but still within 1/4"
Only shot a coyote with the 120's, instant death through H-L area, not massive hide damage.
One hog, 180 lb., with the 130 TSX, dropped, through shoulder/ spine, again not a lot of collateral damage, but you hardly ever see those hogs torn up much because their hide is so tough, they don't seem to explode badly.
Have been deer hunting off & on, but haven't pulled the trigger on one yet to know about effect on thin- skinned game.
Very mild recoil, but that long barrel keeps the weight at the muzzle. I always (nowdays) wear hearing protection, but don't notice much muzzle blast either.
Next on my list are some Scirocco II's, 130 gr., and some 140 gr. Hornadys; the Sciroccos have an awesome BC, I'd like to see what that looks like in downrange trajectory.

I've also tried Retumbo with those 130 TSX's, but was really disappointed with velocity at just over 3100 fps. Maybe it would be better with 140's, I'd like to have something heavier for elk, but I've seen so many elk shot well with the .270/130 gr, that I'd not be afraid to shoot them with the 130 TSX in .264.

Thanks guys, I'm going to work the 7828 right now, I only have a 23" barrel to work with so will try the slower powders later if this one doesn't work out. If it doesn't then I'll probably also have a proper 26" pipe installed too. I always wanted a killer 264, I think it's a sexy ass cartridge, hate to have a dud.

I'll prep some more cases and take the press out with me next time, I like to do that so as soon as I see pressure I back off, saves me time of either repeat trips to the range or pulling bullets. this place is nice in the fact that they have a little room there I can use for this. one of my presses is on a light weight stand easy for transport.

I have found that 7828 works best with 140 grain bullets (Nosler Partitions) and can get a muzzle velocity of 3,165 fps with a published load from a 24 inch barrel Winchester M70. I have found that 7828 also works well for 125 grain Partitions, but that 4350 works better for 100 grain bullet loads, especially in terms of accuracy.


Best of all he loved the Fall....
