In other words, I'm tired of cleaning heavily fouled barrels.
There seems to be an inverse relationship between cartridge intensity and barrel fouling. The .30-06 seems to be easier to clean than the .264 Win. Mag. I seem to get more shots between scrubs with the .222 Mag. than the .25-06.
Has anyone just given up on the overbore rounds because the cleaning is a nightmare?

You can cut down a lot of the fouling if you break in the barrel. It means a LOT more cleaning though. Get the bore down to bare metal and shoot one shot. Then clean to the bare metal again and shoot another, clean again. Do this for at least 20 shots so be prepared to spend a day at it. Then clean after every 3 for a while.
You can also power lap it with the Tubb's system.

Wipeout is bore size "stupid". It doesn't seem to know what size "straw" it's working on. AND IT DOES WORK!! I used to hate small bores. Now it just doesn't matter. Let the wipeout do the work....push it out with a patch. Put a little oil in the barrel....done.

I loaded up some prepped 308's tonight and then did 20 243s from scratch. I was thinking of how much I always liked the 243 but that I would be putting a barrel on it some one of these years. Doubt the 308 will ever wear out.

I don't clean the rifles inside much any more and they seem to shoot about the same.

Is it enough to make you choose the .222 Rem., the 7x57, and the 30-06 over the high intensity cartirdges?

A smooth and or well broken in bore does clean easier than a rough one. But other than that it doesn't matter which caliber. If you use the right technique and solvents one is just as easy to clean as another.
Like the earlier poster Wipe-Out has transformed the hassle of heavy cleaning for me. Let it do the work and you won't worry about which caliber fouls more or for that matter too much about a slightly rougher bore.............DJ

I guess I'm going to try Wipe Out and Eliminator!
Now what do I do with the jug of Butch's Bore Shine?

Use the Butch's after the WipeOut. I run a patch or two of a solvent(I like Hoppes-smells so good) after the WipeOut to get the powder residue out. I don't use oil afterward because the Hoppes has a rust protectant in it. I've used this system for two or three years, and my guns shoot as good as they have ever shot. I honestly can't remember the last time I used a brush!

I have two 7MM Remington Magnums. The first one is factory. It shoots very well but does take a bit of effort to clean. The second is a M70 that I've had rebarrel with a Lilja. A little Butches a good brushing and about three to four patches with this solvent and it's as clean as the Remington is going to get. This barrel also has almost no coppering.

So in my opinion the amount of powder you're burning has a little to do with it. But more importantly the quality of the barrel means much more.
