Hi all. Title pretty much says it all. I have awesome rifle in 6br, built on Remington 700 action, sitting in Elisio stock. It is a very accurate rifle, easy half moa without trying. But then, I am not competing, and for hunting 6br is a bit underpowered. In your opinion folks, what do you think, should I go through all the trouble of switching to 243wssm? I have heard 243WSSM is tricky to load for. I am mostly concerned about losing accuracy with such conversion. And performance-wise, if I am getting 3000fps with 95gr bullets, how much can I expect to gain from such conversion? I am not even sure Elisio's specialized 6br mags can be machined to accept much fatter and a tad longer rounds. Other things are pretty much straightforward re-chambering and swapping bolt for. 540? Or am I missing something?
243WSSM good, bad, and is it worth switching from 6BR

I have a .243 WSSM, M70 Featherweight, and am certainly pleased with it's performance. There was a time during load development that it was almost destroyed out of hate. They are pretty finicky in my experience. The major short fall is
high quality brass. The necks are very thick, and not very consistent. Winchester were the only ones that I have personally tried, with at least a dozen different bullets, and at least 6 different powders.
The 6BR, on the other hand, with Lapua brass, and VV N135 and pretty any bullet you try will give you great accuracy. With 95g bullets you mat be looking at about 300fps difference.
Feeding issues with the WSSM are also a consideration.
Hope this helps.

I had a Winchester Coyote in .243 wssm that I regrettably sold that shot very well....honest 3/4 MOA, loved 70 gr. Blitz kings and shot everything well up to 95 gr. Nice accurate hunting rifle.
For a precision rig there are better 6mm choices and as mentioned the brass is pretty robust and hard to work with.
