Remington 260

I just sent a 243 rifle to be rebored to the 260 did I mess up?

Not if a .260 is what you want. I have never heard re-barreling called "rebooting."

Who did you send it to and what barrel did you pick? What twist and length?

Clearwater will do a good job on it.

Just curious - Why would you think that ?

A .243 can be rebored to any of the other calibers based on the .308 Winchester (.260, 7mm-08, .308, .338 Fed, & .358 Win), provided the barrel's thick enough @ the muzzle; and the .260 Remington's the ballistic twin / modern equivilant of the venerable 6.5x55 Swede.

.264 cal/6.5mm is known to have bullets with good BC and SD relative to their weight. The cartridge will shoot the projectiles at adequate velocities. It will do it's job pretty well if you ask me.

I've got a 260 and hunt with it. I have used 120 grain Nosler BT's and now use 100 gr Nosler BT's. Just for info, with the 120 grainer I use Reloader 17. With the 100 grainer I use IMR 4064. If you intend to hunt with the rifle, either bullet will work fine. Some might say that both bullets are too light, but with the 120 grainer I wanted to get as close to 3000 fps as possible, but my barrel was too short to get where I wanted. So I switched to the 100 gr Ballistic Tips and they seem to work just fine. If a 100 grain bullet isn't enough, why don't they say that about that same weight in the 243 or the 257 Roberts. It works fine.

I am no fan of re-boring. I always use re-barreling as an opportunity to step up to Shilen or Hart barrels; occasionally a Mcgowen.

I personally thing a .260 is far superior to a .243 in every way except one - commercial ammo availability. Mine shoots 140grn Fusions just fine.

I have never been much of a fan of the 243. There are too many cartridges that are superior to it. For small game, the 22-250 is better suited. For large game, the 260 is better suited. I have a lot of rifles that are chambered in different cartridges including 243. Of course this is just personal observation.

Because the 243 and the 257 have smaller bore diameters. 100 grains is a heavy bullet for a .243 bore, a medium bullet in a .257 bore and a very light (for big game) bullet for a .264 bore. It all has to do with sectional density, a function of bullet weight to bore diameter which a lot to do with how well the bullet penetrates.

The 100gr .243 would also have a higher BC than a .264 in the same weight allowing it to carry energy farther and help reduce the wind's influence on the bullet's flight path.

The heavy 6.5's whip the six, but a specific weight being discussed here is heavy for the six and light for the 6.5, giving the 6 the ballistic edge.

Read again. I never said that. I said that a 100gr 6mm will have a higher BC than a 100gr 6.5mm. which is true if you compare VLD profile bullets.

The diff in BC between 100 grainers in 6 mm versus 6.5 mm isn't going to matter even a teeny bit to the deer or to rifle/bullet performance inside 400 yards. Talk of "ballistic edge" of one over the other is hardly worth the effort. And for what it's worth, I'd much rather have the 6.5 caliber 100 grainer. That's just me, and is how I feel about the two calibers. I can't help but think that folks see that normal chat about the 260 includes 140 grain bullets, and that makes a 100 grainer by comparison sound tiny.

In my one year of use of that bullet on deer, coyote, and pigs, it has worked just fine - as long as I do my part.

BC is sectional density with a form factor for the shape of the bullet thrown in. So, yes, I'm not surprised that a heavy-for-caliber 6mm 100 grain bullet has a better BC than a light-for-caliber 100 grain 6.5mm bullet.

The problem is that it's a distorted comparison, for the same reasons listed above in the discussion about sectional density.

My wife killed 4 nice whitetail deer with her .260 before we got married. After we moved to Alaska that .260 has accounted for countless Sitka Blacktails and one black bear. If you reload then you made an excellent choice, if not, ammo will be spendy, but still a wonderful cartridge. I am going to buy one of the new Ruger American Compact rifles, too bad it wont come in .260. (I might have to have it re-bored or re-barreled) My favorite powder is Reloader 19 with a 129 gr. Hornady SST.

Bushman, try RL 17 with that 129gr if you want to play. You should pickup a few FPS with a higher percentage burn.

I don't think you messed up if that's what you want but I don't find that the 6.5's do anything all that much better than the 6's and I personally wouldn't have spent the money.

I think we all buy what we want and not what we need. As for me, I've never really wanted a 243 or 6MM, and I wouldn't have acquired a 260 if my wife hadn't said she wanted a pig shooting gun. I had that 260 for 4 or 5 years before I ever shot it much, but once I shot it I liked it. I'm sure I'd feel the same way about a 243 or 6MM. Where I grew up, the deer were much bigger and the 270 was thought to be the right 'medicine'. Here in central Texas the deer are rather small, and now I have hogs and coyotes, which weren't an issue in eastern Louisiana back when. Most likely, a 6MM would be just about right for what I hunt now, but I already have the 260.

Doyle, I have yet to need a second shot with my load, if it aint broke dont fix it. I live in a heavily wooded area where shot beyond 100 yards are rare, velocity isnt as important to me as it is to some. Powder is too expensive up here for me to just experiment, at $35-40 a pound I tend to stick with what works.
