I finally got my new .264 to the range yesterday.
Lookin' for info about what has worked well for other shooters. I've got a 27" Hart with a 1-9" twist which Hornady said would be good for that bullet. Lot of variation in load data. Some books min is heavier than other books max.
So far all I've tried is Retumbo and got a 1.4" 200 yard group with 63.5 grains, what Hodgdon calls max. (I started low and worked up.)
I was kinda wondering what other people are using under the 140 AMAX? Lookin' for info on 7828, MagPro, RL25.
If it doesn't shoot that bullet good, I'll be a little disappointed but ok 'cause it is really shooting the 120 grain ballistic tip pretty well. I went under .6 at 200 with H4831.

ramshot magnum worked pretty good for me with a 264 and a 140grain bullet.

No 264 but my 260 sure loves that bullet. It's a fun one.

65 gr of 7828 under a 130 barnse shows some over pressure signs for me. And the barnse has all those relief rings cut in it so if anything it should be more forgiving for pressure.
I like this "work up to it" advice.
I worked up to it in increments that were far to large, being a rookie & such.
I have to find a happy place between 62.5 gr and 65 gr, but I'm definately sticking with the 7828. my 264 was a 1.5 - 2 inch rifle at 100 yds with factory loads.
I'm not done yet but I've not had trouble repeating .750" groups thus far with the 7828.
Something clever here.

What I used....it worked good.
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

I got good results with R22 and a Win Primer. Consistantly under 1"(100). Don't remember the charge(I'm at work), but it was near the top of what the Hornady book lists. I was pretty happy with it. The bullet was seated where I wanted it to be and still fit in the magazine just fine. It's an older Rem. 700 with the blued stainless barrel.

If you are using the bullet for fun and long range varmints, they are the bomb! Don't even think about using them on game. I can't even get them to penetrate an antelope sufficiently to put them down fast. They flatten out like a penny. They are dang accurate, but will leave you wanting more on game. The 162 grain 7mm's are a WHOLE different animal and work fabulous on game.
I shot a nice buck antelope at 420 yards with the the 140's shot out of a 6.5-06 at 3,000 fps. The buck stood there and soaked them up. No penetration at all (about 2 inches), then pancaked. Strangest thing I have seen. He finally tipped over, but no trauma at all and caliber sized entrance holes. no stirred up innards, no exit holes, no penetration. Left me scratching my head. Flinch

i've killed deer with them from 60 to 379 yards and have had fantastic results. the deer at 60 didn't go all the way through, found it on the off side hide just behind the shoulder. all the rest have been pass through with major internal damage.

it's a MK4 4.5-14M1. i switched it out for a MK4 3.5-10 M1 and put that one on a heavy 308. Can't like the eye relief on the 4.5-14's though i do have a couple. thanks, I love that rifle! the buck was a toad!!! for perspective i'm 6'5" and clipping 300 pretty close in this picture...

I took it to 65 grains of 7828 this afternoon. And to 64 grains of RL25. The RL25 was more consistent but the last 3 shots, with the max load of 7828, went into 0.49" center to center at 200 yards. Oh, yeah, that's with virgin brass. Lookin' forward to loading up the other half box and see what happens. I may have to upgrade optics. My old std duplex 4.5-14X loopy is not very clear anymore, it's had the snot beat out of it in the 15+ years I've owned it. Worn out several rifles, fallen off a cliff or two .. Thanks, all, for for the input! I'll be offline now 'til about 11/7.

Well Tom, for a 6.5 bore, I'd still say the best velocity is going to come from powders in the H 414/W760 and or 4350 range...
those slower powders are going to be hampered by the bore diameter of the 264...
as for the old Leupold... time to send it in to the factory, get it refreshed.. and have it back in a week...
Paul W... what a deer! its daddy must have been a Steer! Congrats!
