Why is there no coatings used in rifle throats to slow erosion?

[QUOTE="shortgrass, post: 575500, member: 24284"] I recently built a rifle from components I had in stock for awhile in the shop. A 6mmXC. I "broke-in" the barrel, bore scoping throughout the process, until fouling subsided. Took 55 rds. I throughly cleaned it and scoped it again. Seemed like the "corners" at the throat/lead had 'rounded over' , a bit. I set the barrel back 1/2 a turn and re-set the head space, then fired two more rounds, cleaned and inspected. Looked good, so I sent it to Tru-Tech for Meonite/Nitride processing. Took about 5 weeks, no big deal. Now, for the test of time and round count. I haven't had time to shoot it, yet! I decided to try the Melonite/Nitride because several bench shooters I know have used the process and say "there's no effect on accuracy and I get at least 1/2 again as many rounds down the tube before accuracy begins to fall off as I usually do with a barrel that hasn't been Nitride treated". If it effected accuracy, these guys (bench rest shooters) wouldn't even think about using the process and they do shoot barrels to "high round count" (every round fired is recorded in their note book). It looks promising, to me. And, the rifle will make a good display model along with my others, this next Feruary, at the OKC Backwoods Expo. [/QUOTE]
