bigorange Report post Posted June 13, 2014 Quick search didn't return anything...one of my buddies just bought a new .308 and the manual recommends running an ammonia wipe through the barrel between shots for the first 10 shots. Any idea of ramifications if this is not done? Any other recommendations on break-in period? He's not looking for long range use, just general use for elk and deer hunting for himself and his kids... Thanks! Share this post Link to post Share on other sites
willhunt4coues Report post Posted June 13, 2014 Get you a good COPPER solvent (some contain ammonia) and a good carbon solvent. Clean the gun first very well then fire 1 shot then get the carbon out first then the copper out. To make sure you have got all of it out look in the barrel with a light if you see copper keep cleaning. When you finally get it all out fire another round then clean again. Do this for the first 10. Then fire 3 and clean for the next 20 rounds then fire 5 and clean for another 20 rounds and you should be good to go. The only reason you are doing this is so you will be smoothing out the tooling marks left in the gun from when it was cut and if you did not clean out the copper you will not be smoothing anything out. I use Pro Shot 1 step cleaner and Pro Shot Copper Solvent. With my Shilen barrel i was told that I did not have to do this but did it for 1/2 the shots anyways, Better to be safe then sorry.

Guest oneshot Report post Posted June 13, 2014 I've always taken the firearm apart and COMPLETELY cleaned away all of the heavy packing grease they put on it before fireing a single shot as a first step... Share this post Link to post Share on other sites
rossislider Report post Posted June 13, 2014 http://www.montanaxtreme.com/recommended-cleaning-procedures/I've tried a couple of processes and like the one described here the best. You don't have to use their products. Man other companies make their own version of the same stuff. I worked through this process over a few different trips to the range so I could take my time and keep my barrel relatively cool.
