Barrel flush Oil (for a cheapo hobbiest)

[Danny1788]

I used the cheapest pump I could find. It’s a water pump from harbor freight. I do use magnets is my buckets and my catch pan. I had to change the filters a few months back because my pressure had gone down, first filter was packed with black micro grain shavings, I was impressed that the filters caught it.

I have for a while been using Habcool Gun Drill Oil in my circulating flush system for reaming. I use Habcool 318 for my threading. This was recommended by another on the PM forum. I called and spoke with them and listened to their recommendations. I have had fantastic performance with it. Beautiful threads and completely eliminated any reamer chatter. Another local rifle builder was having chattering issues with certain reamers, swapped to the gundrill oil and solved his issues.
It isn’t cheapo but it pays for itself every time I cut a beautiful chamber that performs as it should.
