Thread: re barrel from 243w to 260rem

Thinking of project next year my rem m700 sps in 243 has had lots and lots of rounds down the tube and accuracy has never been that great in that barrel it has always had a dull bore, never bright and shiny. I have shortened the barrel and suppressed it and with lots of trail and error with reloading i have gained reasonable accuracy but its been a problem child very fussy when compared to my 223 and 308 that with reloads i had instant success.
So i think its time to re barrel and was thinking changing it to 260rem with a similar contour barrel and suppress it.
What powder and bullet combo are others using i have heard that adi ar2209 works well.
