Re: I have a SHAW barrel ordered - what can I expect out of it?
I just got the low-down on tubb's final finish "bore lapping" bullets, which are basically bullets that have been rolled between 2 steel plates, forcing various sizes of valve-grinding grit to become embedded in them. They come in boxes of 50, with 10 each of 5 progressive grits. But the word on them isn't very encouraging, as they wear down the barrel, ESPECIALLY the throat area, at a highly accelerated rate. They "may" improve accuracy in the short term, but it is at the cost of greatly reduced barrel life. Being that the 7RUM is already known to burn up barrel throats rather quickly, it goes against my better judgement to send highly abrasive bullets down the barrel, even at low velocities.
