I didn't notice any difference in the ignition time, even though I know that ffffg has a faster burn rate (although very minute) when measured electronically. The fffg powder used as a prime worked very well with the RMC liners I use.

I'll try and remember that next time. Also try the outside edge of the pan too. I was just reading a post on the same subject on the other ML forum. There are several techniques that they use that I haven't thought of. One is using a pipecleaner in the touch hole to keep it clean during swabbing between shots! I find this hard to believe to work as I ran a slotted dowel with patch down the bore to wipe the chamber area and could never see the patch through the touch hole port. Second is the use of FFFg as the main charge in lieu of FFg. Again, I can't see a reason why this would be different.
Someone else got a solution?
