rem sendero .264 mag

case capacity wins again! :D

when the 264 came out, other than H870/7828, there was few powders slow burning enough to really fill up the case. now we got Retumbo, RL25, US 869, H1000, as well as 7828. Launching a 140 @ 3100 fps + with a 26" tube is totally within reach. That bullet has a BC of .490+, and a good SD of .287, and has good downrange numbers.

A 270 Win w/ 140 @ 2950-3000 fps isnt *too* far behind, but BC isnt as high (.430-.460), and SD is .261. Burns 60 grains of powder still. No doubt a great cartridge still (IMO one of the top five choices for deer hunters coast to coast).

Filling a 264 case with 4350 is like stuffing 4064 in a 300 Mag. Just aint right! :p :cool:

I bought a 264 two years ago and if you are into reloading it is an excellent cartridge. The most attractive aspect for me was the BC; fast and flat. Do not worry about throat erosion or burning the barrel out as long as you use the right powders and properly cool your gun down while at the range.

People will still argue whether the 264 or 270 or 7mm is better, but in reality most people don't shoot well enough, often enough or far enough to ascertain the difference.

Buy one because you want one, then enjoy it!
 
Another with no regrets on a .264 Win Mag

i love my .264 mag, i paid to much for it. i knew i was paying to much, and still i walked away smiling.

I had one put together on a Rem 700 action. I wanted it. I had it done. I too have no regrets................. :cool:
 
Yes we all know from our armchair reading that the 264 Win Mag is:

- "Overbore"; :eek:
- "Inefficient"; :eek: and
- a "Barrel Burner". :eek:

Overbore - costs at most an extra nickel a round to shoot.

Inefficient - the 270 achieves the same velocity at the same pressure with less of the same powder. See above. So what. The 30/30 is more efficient than the 308 which is more efficient then the 30/06, which is.......... Pretty much meaningless, in a practical sense, unless the extra nickel a round you spend stresses you, and the big potential velocity upside of the round is not worth it to you.

Barrel Burner - the more powder you burn, the quicker the barrel will wear out, which is generally true. Use of spherical powders seem to reduce wear, and keeping the heat down helps, but the barrel will wear out faster. If you shoot a lot and replacing a barrel after 5,000 rounds as opposed to 10,000 stresses you then it's a factor.

If you have a 25/06 you should sell it and buy a 270, if you have a 270 you should sell it and buy a 280, if a 280, a 30/06,.............

I don't have a 264 Win Mag, but I do have a 6.5/300 Win Mag. A case full of US869 with 120's puts me over 3500 fps and with 140's to almost 3300 fps. With a 24" barrel. Here's another myth - that the 264 Win Mag needs a 26" barrel. Armchair folks seem to believe that "Overbore" cartridges need a long barrel. I've seen such crap as "a 7mm RUM with a 22" barrel will be slower than a 7mm Rem Mag with the same barrel length. Yes, the loss per inch of shorter barrel is greater with the larger cases, but capacity still rules.

You are 100% right, I am avg 3200 fps with out trying to hard with RL-22 powder and Over max my a smidge but not pressure signs but accurate as hell!
I tried with 120 gr bulles and do to the fact accuracy was suffering i stopped but i hit 3400 fps.
Advantage with handloads over a 270 win, ya you bet!

Anyone that owns both a 270 and a 264 Win mag, and actually loads them to their potential knows the difference!! I've heard and read a lot of snide comments, like: A 264 is just a loud 270, a 264 is a 270 that burns more powder, on and on, ad nauseum. I have used Retumbo, Reloder 25, H1000, H5010 and Vihtavuori N170 to achieve superior performance from the 264 (and the difference in equal length barrels IS more than 100 fps.) The 264 is certainly a "niche" chambering, and many can do just fine without it, but if you can justify owning one, there is nothing quite like it!! Regards, Eagleye.
 
That word "OVERBORE" it's synonymes with two cartridges, the 220 Swift and the 264 Win. Mag. two of the highest performance cartridges ever to come out of the Winchester stables. The funny thing is there are many many more overbore cartridges today then were available during those glory years but rarely does one attach the overbore label to them, why!
It doesn't matter, I don't own one but two 264's and wouldn't sell them. They do what I ask of them and have pizzazz factor, and that matters:D
bigull
 
Anybody that has owned and reloaded for a 264 would never compare it to a 270.I sold my 264 but with a 24 inch tube 3250 was not hard to get with
140 grain bullets.The 264 is a flat shooting hard hitting round,good for anything including moose and big bears.The new powders really wake this cartrige up I had some factory loads that I ran over the chrony.
140's didn't even break 2800, diff story if you handload.
 
264 win yea

I have always wanted one and bought one at bashaw sports in a sendero and sent it to my gun smith to have it blue printed match 28" barrel bedded and trigger adjusted to 1 pound . my smith does superb and in 2 months will have her home working up a load for her:D
 
I can easily get 3150 fps with 140 grain bullets in my .270 (24" bbl) using 60 grains of RL 22. I can get marginally faster with a .264 Win Mag, but I'm using a 26"+ barrel, burning 10 grains more powder, making a hell of a lot more noise and heat, and wearing out my barrel much faster.

Overbore is an objective condition, not a moral one. A cartridge that's more 'overbore' than another doesn't mean it's bad or evil, but it does mean you're getting less (in some cases MUCH less) velocity return on your additional powder 'investment'.

Doesn't mean you can't own one or feel good about shooting one. I've always wanted one in a pre-'64 model 70, but I'm absolutely not surprised that it's dead, or nearly so.

You must be mistaken. 3150 fps with a 140 out of a 270 with a 24" barrel, then you are running 70K+ psi, even using the slowest of powders (and RL22 isn't even close).

What does it mean to "easily get" a velocity anyways?
 
That is cooking for sure! I run 130 gr Ballistic Tips in my 270 with H 4350 ans 4831 and have not pushed to far over the 2900 fps mark! and avg load i backed down to 2850.
I have not tried the Allient powder however.
 
264 win mag

I decided to try this cartridge after loveing the 6.5x55mm so much. As others have said 3100fps can easly be reached in a 24inch barrell using new powders. The only thing no one has said anything about is the short throat on a factory 264. Get it throated..... increases velocity and bullet slelection. shooting both 26 and 24 inch barrells with the same load gave me an average mean difference of 35fps.

Good point. I believe that they were throated for the "bore-rider" bullets in use at the time, such as the Rem 140gr Core-Lokt (the Hornady 160gr RN is another). Those bullets can be seated way out, but newer bullets lose a good 0.250" which can add up to 7 or 8 grains of powder space.
 
Well, if the 6.5-284 can get 3050fps with the 142 SMK 'safely,' then you'd expect that the 264 could 'safely' be pushed a good bit more than that.

As far as the 270's concerned, it's apples and oranges. If the golden standard is how fast we can push a 130 or 140 grain pill, then there's no contest. Likewise, if the golden standard is 'efficiency' and barrel life, then my 22lr rules the world. But the bottom line is that the 264 delivers more energy, with a flatter trajectory and less drift than a 270 right across the spectrum. Small difference, maybe, but so's the difference between a 270 and a 7mm08 or 280 or 25-06 or 30-06 or a 7mm mag, or any other number of cartridges.
