When done with the barrels, we moved into the bolt assemblies. We also gauged for throat/lead erosion, and muzzle erosion. This damage was viewed by all, and drove the point home of why we recommend using bore guides, and only pushing brushes and jags from chamber towards muzzle. A few of the barrels had large pits and craters from using solvents that contain ammonia, where the ammonia was allowed to soak. Several rifles showed damage due to the lack of not using bore guides, and scrubbing with brushes back/forth (where we recommend always brushing from chamber to muzzle and only going one direction). Using the borescope and bore camera, Officers get to make a detailed look inside these barrels. Note: A couple of the rifles in this class had been passed through several Officers before they landed in the current Snipers hands.

We showed several types of copper solvents, and showed the proper procedures for using these for fouling removal, and how to keep these from damaging things. We also supplied Barrett Heavy Bore Cleaner, and showed how well it works. We showed different types of bore foam, and showed our favorite being Outers Foaming Bore Cleaner. With discussions on fouling, it is our recommendation that Snipers keep a log of their maintenance in addition to shooting log book notes, as over time they will start to see a pattern of how each individual rifle performs with what levels of fouling and maintenance, which may give them an idea of when and how to clean and to what level.Įveryone was allowed to clean their barrels if they wished, and were allowed to use different cleaning products and solvents. We discussed fouling of different types, and how it effects accuracy in sometimes a good way and sometimes in a bad way. Everyone was allowed to up close inspect their barrels before cleaning them, which gave everyone a view of the rifling, fouling, what different types of fouling look like, areas of fouling, corrosion, erosion, etc. Everyone was supplied with denatured alcohol, and swabbed out their barrels, which allowed them to borescope the inside. Once field stripped, proper maintenance was shown of where and what to clean, how to clean it, and why some areas need specific cleaning. We also went through the eight cycles of fire, function checks, and basic inspections. A short session of nomenclature was covered, at which time covered every feature and exterior piece of the rifles. All students were supplied with samples of Slip2000 "EWL" Extreme Weapons Lubricant and #725 Cleaner Degreaser, which allowed them to clean and lubricate anything that needed it. We also provided lots of gunsmithing/armorer tools, torque wrenches, gauges, borescopes, cleaning equipment, bore guides, vises, etc.
Students were supplied with their own set of basic tools that are necessary to do the work on their rifles.

We started with going through the course manual that all students are given. The Student base were all Law Enforcement Officers from Montana and Wyoming. Officers are welcome to bring whatever brands and models of rifles they wish to class, but we only have parts for the Remington, Savage, and Winchster/FN type rifles with us.
The weapons Officers brought to class were a mix of Remington 700's, and Savage 10/110 type rifles. and the Winchester / FN 70 series, as this is what we have parts with us for. The rifles we cover in this course are the Remington 700, and Savage 10/110 type rifles. The training room offered plenty of table space, decent lighting, and a screen that allowed us to project some animated graphics of the weapons system, powerpoint detailed pics of gun parts, and especially when looking at finer detail things like machining, stress cracks & wear. This was our second time doing courses in Helena, and we look forward to many more in the future. We conducted a 1-day (8-hour) Bolt Action Sniper Rifle Armorer Course at the Helena Police Dept.
