Might and might not - depends n how many 'fines' you produce which can retard ignition. I'd be happy with Swiss 4F but if it cost more than GOEX 4F - probably would use GOEX.
GOEX 4F is faster than GOEX3F in ALL my guns. The 'feeling' of speed is very slight, but it's there, just as it is in Larry's timed events. & Gary & Gary, you are not alone - Tayor, Len & I also 'feel,see, hear' the difference- except we don't miss. HA!
