Has anyone worked up loads in rifles with extra long barrels

The 264 wm is one of my favorite rounds. I'd have one myself if it wasn't for the belted cases. The thing that hurt the 264 wm was bad press and the introduction of the 7mm rem mag with it's capability to throw bigger bullets. Which made it a better all around cartridge for the one gun hunter.

Wear at the crown is a major culprit to barrel wear. Another is not taking proper care after use and during storage. I was told by two different competent gun smiths that barrels don't wear out they rust out. Tiny little spots of rust, not visible to the eye, form inside the barrel and corrode the bore. The bullets are shot threw these rust spots and drag the rust down the barrel scratching the bore. Another is putting the gun in the case before it cools down. Condensation forms, which forms rust.

It's not a good idea to shoot any barrel at maximum pressure constantly. But, it's nice to know it can be there if you want. If I have the capability to throw a 130gr bullet @ 3550 that doesn't mean that I have to. If I reduce the charge just a bit. I'll still get very good velocity without running at max pressure.

The most important point I'm trying to stress is. Long wizzbang cartridges aren't neccessary to achieve max performance. As an example. The weatherby's are long rifles with long cases. If you get a rifle with a short action that shoots a short fat round and lengthen the barrel so the length of the gun is the same length as the weatherby. You can have a rig that will perform as well as the weatherby. This would be true with the 270 and the 7mm in the new short mags. I haven't done any figures with the 300 as yet.

These new short mags are very versatile rounds. Rifles with short barrels for light weight mountain use to heavy long hard hitters can be designed around them.

Did you know also that to some extent, the 7mm Rem Mag and 300 Win Mag ARE short mags? Previously, the 300 H&H set the standard. That requires a longer chamber. Made more sense to have magnums that fit 30-06 length chambers. I don't know if that was the case with the 264 WM, in fact, to me, the 7mm Mag is merely an extension of it, a round that picks up where the 264 leaves off, and goes on up to the heavy-for caliber stuff. Nonetheless, the 7mm Rem Mag, if properly loaded, will throw 160 grain bullets as fast as the 264 can throw 140s.

Proper bore care is essential. Copper fouling kills accuracy, and powder fouling corrodes the bore. How a rifle is stored plays a major role, I store all of mine if a vault with a dehumidifying device inside. I try to oil lightly, excess oil can get messy later on. I also scrub the heck out of my rifles' barrels to remove all visible evidence of fouling and then some.

With the 7mm and 300 Short Mags, you're going to run into a problem: bullet weight. You'll be ok until you get over 160 grains for the 7 WSM and over 180 in the 300. After that, your bullets really cut into your powder column.

Check out this site:

http://www.long-range.com/

This site hosts some of the nation's best shooters. You want the advise of the Palma and Long Range shooters. These events are shot at 800 - 1000 yards mostly with iron sights.

It's a must that bullets remain supersonic out to the target. When a bullet slows to trans-sonic speed it begins to destabilize and yaw decreasing accuracy.

To ensure this velocity at range, these shooters shoot 30 - 32 inch barrels with slow powders. They have a wealth of experience and are willing to share it.

I've found some good slow powder loads for the 30" barreled 270wsm.
I got a deal on some Winchester Magnum Rifle powder. It looks like this may be the powder of choice for 130's and 140's.

Well, now that I've had the opportunity to shoot this long barreled 270wsm. The thrill of the long barrel is gone. I want to start using it for the mulies over on the eastern portion of the state. Just too much barrel to carry around.
I dropped it off at the gunsmith a couple of hour ago to have the barrel lopped to 26" with an 11% crown.
It was shooting Hornady 130gr Interbonds and 140gr Nosler Accubond at 3 shots the size of a dime. We'll see what it does when I get it back.
It should shoot as well but it's going to be easier to carry all day. It's by far the steadiest holding rifle I've ever owned.

Should keep the same amount of accuracy, as long as the rifling around the new muzzle crown is as good as the old.

Yea, I'm sure it will.
It's a real looker with the custom stock, I'm proud to say, I did the work on.
Dark walnut with wenge accents (african wood that looks similar to a darkened zebra wood) and 20 lpi checkering.
Dark brown Decelerator recoil pad and a 3x-9x 40 Burris sitting in medium rings.
I don't get it back until the 28th of July. That'll give me enough time to set some good loads.

That's the same exact scope that I like to use!

Other than target scopes. I've never used anything bigger than 2x-7x 32 on my hunting rifles until I purchased the 3x-9x 40 Burris.
The 270 wsm looked like it deserved a 3-9. I spent a couple of days looking at various scopes. Was on my way down to the store to get another Leupold in 3x-9x and a friend mentioned that I should look at the Burris first.
I ended up with the Burris. Very nice scopes. It just happened to be on sale, at that time, for almost half of what I was going to spend on the Leupold. I'm very satisfied with the Burris.

I love it that you can see your groups on a target from 100 yards away with the Burris. I also own a Zeiss, and the Burris is about as clear as even that.
