I would look hard at the 243 AI. Already have the brass, none of the 6mm calibers listed above come close the beating it performance wise, and simple to form cases. Paired with a 1:7 quality barrel and high b.c. bullets available, you will have a gun capable of across the board accuracy

You seem to like things with extra velocity so if you're going to switch to something different and buy a new set of dies anyway, I wouldn't even bother with the tiny increase of AI'ing a 243.  Save yourself the extra time of fire forming, make it worth your time, and go 6-284.

You beat me to it! The 6x47 Lapua is a good one too. It doesn't really offer an advantage over the 243 Win, it's just a little less vanilla. :chuckle: The 6 XC is in the same performance range and has been a proven performer too.

The .243 Win is solid. I imagine you have a ample brass supply. Might be worth staying with the same chambering.

you are correct as I have tons of 243 components.  I do have a Redding die set for 243ai.   
Just sold a rifle the other day that I had for 3 or 4 years and never shot it once, thatís my barrel $$ now.   When I first rebarreled this rifle I was wanting 243ai.  Maybe now itís time to do that. Probably the cheapest route since I have brass and dies and bullets already.
Plus Iíve been thinking about getting a lite weight hunting barrel for my vanguard in 338edge   


This just blows my mind, how can you have a rifle for 3 to 4 years and never shoot it   :hello:

you know me well, 6/284 has always peaked my interest.

In a short action, if you plan to get the max out of a 6-284 shooting the heavies, you'll be limited to single feeding them but I think you mentioned you were already doing that so it won't really be anything new for you.  Even if you throat a 6-284 to shoot the heavies at mag length in a short action, you'll still have a fair amount of case capacity advantage over all the others.

My 6-284 was the very first custom rifle I ever had built.  Funny thing is, I was all set to have a 243AI built instead, already had bought the dies and brass even.  Before the gunsmith that built it for me stuck the reamer in the barrel, he called me to make sure a 243AI was what I wanted.  He asked me if I had given any thought to building a 6-284.  About the time he said you'll get more velocity with less work and expense a light bulb went off and I quickly changed my mind.  I've been a 6 & 6.5-284 fan ever since.

was a sporterized muaser in 22-250.  Barrel was probably shot out, crown looked like hell.  Guy wanted it so I said make an offer. 

6/284 is sounding better every time I think about it.

Pretty sure the 243 barrel is on its way out. Thinking about playing with a new cartridge for a barrel or so.  Looking for some ideas to ponder. Would prefer to stick with the same bolt face but might change that, 6mm or larger cal., run in SA ai mag, and not a creed bore.

Just wondering why? Did you run a good optical borescope through it?  I've always been surprised as to how many folks sell a rifle or rebarrel it due to it "being shot out" only to find it was copper fouled from years of just standard cleaning.

no I cleaned it to bare metal. Never has this barrel had copper fouling.  I stopped talking about it since folks never believe it but zero copper.  My cleaner tunes blue as hell with copper but zero copper from this barrel.  Zero!   700 is not unheard of for 243 run like this one has.  I can probably get another 300 from it for hunting but accuracy is past what I expect.  At 100 1/4Ē is normal but velocity spread makes it useless for my purposes.   Iíll say it once more. Zero copper weather you choose to believe it or not is your choice.  I just know what I see.

My wife has a .243 with a shot-out barrel.  Talked to a gunsmith once about re-barreling it and he tried to talk her into swapping over to a 6mm remington caliber.  He said the geometry of the case design provided some benefits over the .243 win.  I don't remember the specifics but he was very adamant on the 6mm remington over the .243.  I don't have first hand experience between the two.

I have a rifle that quit grouping went from under in inch to around 2 inch groups. I spent several months removing coper fouling. I thought I was doing a good job cleaning, but found out I was not getting all the copper fouling out. when I say I spent several months I mean every time I entered reloading room I put a patch of hoppe's   or some other solvent down the bore. It took all that time to get a patch out that did not turn green. wonder of wonders I then took to the range and it again shot great. the rifle was over 20 years old and I bought it new. I vote for if it is not broke dont fix it. as far as caliber asking what other people think isnt real important it is your money and your rifle. I would stay with a common caliber and away from wild cats I have a 250 Ackley and it is neat most wildcats are just asking to spend big on dies etc. anyway have fun with you quest that is half the fun

This boroscope is well worth the $49 to see what is happening inside your barrel.  Need android phone or pc computer to hook to.

No offence meant, just asking the obvious based on my own experiences.  Is it the throat that's showing erosion, or ?
