[obsessed1]

A number of years back I came across a couple of cans of spray on Moly. I did some testing with one of my 308s for velocity/ accuracy ( sadly I did not own a borescope at the time or I would have used it to check fouling as well) my load was tested over a chrony and had a mv of 2586 with an SD of 6 targets where shot at 200 yds. I had 8 3 shot groups right around 1.50" and 2 opened up to 2.25" ( I thought they were shooter error) prone on bipod. These groups gave me a mean to average against.
My first try was coating the barrel as directed and I was going to 5 3 shot groups. Same distance over the crony
First group was 2655 fps average with a 8 SD (1.56")
Second group was 2598 average with a 12 SD ( 2.64")
Third group went back to 2586 mv and SD of 7 ( 1.58")

Obviously the Moly was shot out
My next test was 3 3 shot groups but reapplying every three shots
First group was 2663 avg 5 SD ( 1.43")
Second group was 2674 avg 9 SD ( 1.79")
Third group was 2678 avg 11 SD ( 1.82")

My take away was Moly worked but had to be reapplyied about every 4-6 shots for consistency but unless there was exactly the same amount in the barrel shot to shot SD MV and accuracy varied. I did not have any way to check fouling, But.... I do still have an old can full of moly still on my bench....might be time for another test.
