it's time to rebarrel the 243 I have and I just can't decide on the next chambering! I'm leaning pretty hard toward the 6 comp match just due to the fact that I'm stocked up on lapis brass and H1000 plus I would only need a new Sizer die. I already have a new Bartlien med Palma .237 barrel on hand but I read that the chamber can be finicky on a 5 groove ? Supposedly it was setup for a 237 4 groove , does anyone run a 5 groove with it and how is it doing ? I also searched the depot for data on reloads and couldn't find any. Is there any way to get it setup on quick loads ?
