Specweldtom is right , keep what you have and go to a custom barrel
in one or two sizes larger if the stock will take it.
If the stock cannot be opened up enough for a #5 min taper then plan on
a stockthat will fit a larger barrel (even a #6 or #7 taper would be better
and would tame it down to the point that no muzzel brake is needed.
Heavy barrels seam to be less finicky about the load used (they shoot all
loads well and the right load great.
I use more Remingtion actions for custom rifles
than anything else because
they work great and can be made very accurate,But so can the Weatherbys
but they cost more and are harder to find for a donor action.
With good machine work and very little headspace the Weatherbys will
shoot 1/2 MOA all day long. I have built some that shot sub 1/4 MOA.
Stay with what you have!!!!
