I'm in the middle of a Dasher chamber job, New Krieger, .2361 bore, Heavy varmit contour. I got this hair brain idea about turning some grooves around the barrel over the throat area. These grooves would be about .050 wide X .050" deep and approx 1/4" spaced for about 2". MY QUICK CALCULATIONS SAY IT WOULD ALMOST DOUBLE the surface area for cooling in that area. My reasoning behind this was to provide more cooling in that area. I have shot out a lot of 6br barrels and they have shot very well for me. This will be my first attempt with a Dasher. From what I have read on this forum dasher barrels seem to have much shorter lives than do 6BR's.
My questions are: Has anyone tried this to prolong barrel throat erosion ?
Would this cause detrimental effects such as chamber pressure questions, and excessive unwanted barrel harmonics.
Would the addition of cooling fins be not as beneficial as I hope for ? My thoughts are, that it would extend barrel life but I don't know how much?
I would be using this barrel for F/Class rapid fire where a (20% -?) reduction in temperature might be very helpful.
