    Has anyone tried the following Arsenal mould in 300 Blackout AR?

    I am looking for moulds for the 300 Blackout on the AR platform... The following from Arsenal looks like a good option, has anyone tried it?

    I am trying the 31-165C which is very similar, so far good results. You will have to watch the nose, it's a little large for PC coating.
    Whatever!

    That is what I was afraid of popper. I have not done a lot of PC yet, but I have found that Smoke's red seems to give a fairly thin coat and the black and traffic blue are relatively thick coats. I have order the Lee mould to try, someone sent me a few PC ones that were sized for 7.62x39 and the PC did not hold up well sizing them down. But, they have shot ok and feed well so I am willing to try that mould. I think if asked, Arsenal might make the nose diameter .001 smaller diameter... but not sure.

    The 31-165C is almost a bore rider. I could see where it would have issues with PC. One could almost size that nose down a little though. Their site drives me nuts... that is not listed in the catalog, but google found it by number.
