Home Forums Hunting & Shooting Hunting Rifles 264 Win. Mag.

Yeah I've got one, not sure the box says SF though. Always thought that was stainless fluted.

I do like the rifle.

bearstalker,

If you are going to stick to 100-120 grain bullets, why are you going to a .264 Win Mag instead of staying with a .257 Wby? The real advantage to the .264 WM over a .257 Wby comes from the higher BC 6.5mm bullets like the 120 gr Ballistic Tip (which I'm not sure I would use at full-blown .264WM speeds), 130 gr Accubond, 129 gr Hornady, 130 gr Berger VLD, 140 gr Partition, and even the 125 gr Partition. Granted one can get more muzzle velocity out of the 100-120 grainers, but the wind is the bigger issue, and the bullets with the bigher ballistic coefficient will help a lot with minimizing wind drift. Minimizing wind drift with high BC bullets is where the .264 WM's biggest advantage over the .257 Wby lies.

Hello, I had a 264 built on a new Sako action and had Pac-nor barrel it using 9 inch twist. I used a longer throat so I could seat heavier bullets without wasting powder capacity. I found Magpro and their maxamin charge perfect. My three shot group averaged 3/4 at 158 yards off my veranda. On these match grade chambers my question is by turning necks so chambering is easier does this negate the purpose of tight chambers?

they came in both, the matte was more rare i guess. i wanted stainless, when my ffl ordered they told him they were out of stainless so he ordered the matte. fine with me.

I'm gonna get the parts all ordered up, but I'm thinking I might have you do the fitting.

bearstalker,

Lee, Redneck, and I have been talking the last couple days about a similar build for me. Mine will be on a M70 pushfeed action currently a 7mmRemMag. Ordered a Supergrade Swirly for it today and Williams bottom metal. Lee and I have decided on a Pac-Nor #5, 8 twist, 1.25" cylinder length, with 5 flutes, finished at 26". FYI, this barrel, according to Pac-Nor's weight calculator, will weigh very close to the same as a #3 unfluted.

Sounds like Lee better get his .264 reamer sharpened up. Just wanted to point out the barrel weight similarity by fluting the #5.

Maybe these will come together close together and we can share some load data. The 140gr. Accubond and SST are appealing, as well as the 130gr. Scirroco and the Woodleighs.

I would go with the 26" tube. After all, you want velocity and lots of it, right? I have my Dad's old pre-64 Mod. 70 in caliber .264 Win. Mag. It has a 26" barrel. He loaded 140 grain Nosler Partitions in it and tipped over sheep and quite a few antelope, deer, caribou and moose with it. It was his favorite caliber and his 30-06 and .375 saw little use. My understanding is the 3200 fps mv with a 140 grain bullet is hard to attain. The 6.5 bullets have a good reputation for long range shooting. I want to get a .260 Rem. for my Grankids. If I did not live in Alaska I would probably pull it out of the safe and hunt with it.

I've got the time, AND the reamer..

David, on the Scirrocos, start those loads out near minimum and watch for the pressure to jump.. A very experienced rifleman and reloader near me wasn't able to get decent speed w/o pressure signs.. Max he could safely load ended up about 150 fps under book.. Just FYI..

Thanks for the heads up Lee. I'm pretty set on the 140gr. Accubond. Seen lots of good things about those the last couple years. Some guys I shoot with occasionally, that spend a lot more time "perfecting" loads than I, have been amazed at the accuracy and consistency of the Accubonds. I've put a few through my 300 Roy, but none on game yet.

Lee, Been meaning to ask you about throating. I've got some interest in possibly using 160gr. Woodleighs at some point, however un-needed that may be. Should we talk about cutting this chamber with a long throat for that purpose? Since we have to get a mag box anyway, I was wondering about a H&H length box to accomodate stretched out loads. May all be completely unnecessary, but now that we're rolling on this thing, the wheels are turning. Scary, really!

David

With 26" you can expect low to mid 3100 FPS & 140gr bullets with powders such as RL25, Retumbo, IMR7828.
If you still have some H870 you will push the 3200 FPS mark with a 140gr.
Very curious to see how the new RL50 will do in a 264 WM.
US869 seems too slow for a 264 WM & 26" barrel. Mine would take a max charge of 78gr US869 which gave me just over 3100 FPS.

AA8700 & US869 seem very close in the performance department. I don't know why H870 does so well in a 264 WM, it just must be the perfect burn rate.

I had my 264 WM opened up to a 6.5mm-300 Win Mag. I need to do more testing yet, but so far I am at 3275 FPS with a 140gr Accubond in a 24 1/2" 1-8 twist barrel.



The cluster was my last 3 shots.





Here are the seating depths of different bullets fit for the throat in my rifle.

Thaks Wookie. Good information.

David

I use the 130 Scirroco and push it with 67 grains of Retumbo The data that I have says 67.5 as max but at 67 I got 3225 fps and excellent accuracy so I stopped there. A bullet that you may want to give a try when the become available is the new 120 GMX from Hornady. And if you want to spoil a coyote's afternoon try the 95 grain V max. A charge of RL-25 works good in mine.

Every research article I've read to date has indicated little benefit in going to 160s.. If that weight is needed, it's best to go to a .30 cal.. The .264WM has a rather narrow band of good-performing bullet weights compared to other chamberings..

Got it. Figured you had enough experience with the 264 I could get some good information. Realistically, there's little in North America that can't be taken with a 140gr. bullet.

Is your reamer to SAAMI spec, or is a custom? What I'm asking is if I'm gonna have to turn necks for this rifle, or will factory Winchester brass work?

Thanks,

DW

Why settle for a mere 26" barrel?

Hey Tom, How are loads coming along in your behemoth? You support the muzzle with shooting sticks? Probably just whack most critters in the head with the muzzle, huh? Makes load work-up easier that way I guess. ;-) That build did turn out nice. Post up a couple of pics, maybe some targets. We all need some motivation.

DW

I have not even loaded ammo or shot it yet. (I know I need smacked) it balances quite nicely for such a long barrel.

This spring baby! this spring.

No new pics but I will post one of the old ones.

OMG, Tom, If you weren't in prison, one of us would have to smack you. Wouldn't want Bubba thinking we's beating on his little biaaatch!

Karl does a fantastic job, for sure. What does she weigh? Got her scoped up yet?
