I've tried it with MAP and also with twin burners but for most consistent results I just use the single burner.

This standard burner cycles a .308 in around 7 secs. MAP gas takes around 5.5 secs and twin burners with MAP takes around 3.3 secs but its easy to get it wrong at that speed.

This burner is made up from the gas hose and valve from Chinese camping stove and a Burneze pencil burner.
what temp are you getting the case,s to?
