I plan on using there listed data and working up looking for pressure signs. Any info would be appreciated.
Also looking for any cleaning or maintenance ideas for keeping accuracy after the barrel is coated.
Firts off the barrel needs to be squeaky clean of ALL carbon/copper. Check Berger out on how to break in the barrel for use of the moly bullets. He has a regimine for cleaning also using JB and Kroil.
I have never seen specfic data for them. The friction is lower and to obtain same same velocites you have to bump the powder charge. Pressures are decreased so you can go faster but you have to start working up at higher powder levels.
Accuracy is not normally increased only the lenght of cleaning between shots. There has been some issue in high humidity areas of a bit of increased barrel corrosion as it does absorb water.
Also once you are done with it it may be a bit difficult to clean the bore completely if you want to go naked again as the stuff does linger. There are some methods on the net but I don't recall how it's done., Once I shoot coated bullets,I use tungsten, I don't try to back up. I shot it in some of my 20 calibers but nothing larger.
Let us know your results on the range.
