[QUOTE="Topshot, post: 273083, member: 13285"] Hi Mick, Interesting results! I am not sure what to make of it though. I always assumed that pressures would drop as throat erosion got worse and the bullet got a longer jump to the rifling. This seems to be working the other way about? One thought I have is that you may be getting all the copper out when you are cleaning your barrels but maybe there is still a build up of carbon "powder glaze" taking place in the throat area? Have you tried giving it a scrub with JB bore cleaning paste to pollish up the throat area? My smith recomends doing this at the 200, 400 and 2000 shot period. [/QUOTE]
