So it looks like I am about to build a new 308.
I was wondering if anyone here has any opinions on having a new (hand lapped) match barrel nitrided/melontied. Everything I find online is AR15 specific, and very little about bolt action rifles. But at the same time, everything I find says that it will not effect accuracy (will not make it better or worse). And on the plus side, the barrel will last a ridiculously long time. Seems like the general consensus is, if you start with a crap barrel, have it nitrated, it is still a crap barrel, it will just last forever. On the other hand, start with a high quality match barrel, have it nitrited, it will still be match grade, just last forever.
I have a 4140 barrel on my target rifle and after around 2k rounds, I am starting to get some throat erosion and the surface is got the heat cracking (using a bore scope to see it). So the idea of the nitride/melonite done to it to make it last longer is very appealing to me.
