Re-chamber .243 win to something else?

**alltherage** · 05-14-2016, 04:19 PM

I have an extra axis heavy barrel in .243. Rather than rebarrel, i was wondering if it would be more practical to rechamber to another 6mm or 6.5 mm? What options, if any, are there? I would need a gunsmith presumably. Thanks

Meant just 6mm options

What chamber would you cut? The 243 is a big case when compared to other 6mm cases.
Personally id just buy another barrel in another caliber and have an extra chambering option.

Could you do 6mm SLR?

**alltherage** · 05-14-2016, 07:17 PM

Or 6mm rem?

so where did this get moved to?

If you look at the forum path above the first post it says in the hunting section. In order to rechamber your small shank barrel you would need to Set Back the barrel by removing or partially removing the chamber. This would be determined by your choice of cartridge ultimately. The problem with this is that more often than not you end up removing the portion of the barrel that can support threading the OD to fit your action. Personally I can't see a reason to do this unless you go to a 6MM Remington(Long Action Set up). There is nothing wrong with a 243 and a lot right about it.

There are many "wildcat" 6 mm rounds as well as a the well know 6BR Norma. Most of them are very accurate and some require brass forming. The best might be the 6 Dasher with Norma now making Brass for it.

The 6.5 Creedmoor would be a tight fit.

I have 2 axis rifles in 243, so i want to change 1

Sell the barrel and get a caliber you want. Used or new. If you are on a budget and cant find what you are looking for try ebay.

By the time you set the barrel back, the cost,etc., you can sell your barrel and have a new one made to your exact specs.

I recommended going this way. Just put a pencil to it.

243 AI for sure if you want to rechamber the barrel you already have. But, as mentioned above you could go whichever route you want if you just sold the barrel and bought an aftermarket one.
