its a rem 700 in .243 win. and yes I reload I am pretty new to reloading the 243. Its got maybe 60 rnds through the barrel. I have reloaded for 30-06 a couple years and have crafted some good accurate loads through load development without lapping the bore. but then again that rifle has over a thousand rnds through the barrel. Over time just shooting a rifle will smooth over some rough edges.
I have bedded all of the critical areas in the stock. After reading that article I would be very careful on how many shots with more coarse grits down the tube. without a borescope (which I dont have) I am going into dangerous territory in terms of ruining the barrel. So i figure just a few of each grits wouldnt hurt anything. I may be wrong though.
