roughshooter Posted August 27, 2020 Report Share Posted August 27, 2020 I have the option on a decent size keg of GM3 Black Dot. I understand that this is slightly slower than the original GM3 and is somewhere between GM3 and GM3 Special. I have seen data for 12g 32g (24gn) but not seen data for anything less in 12 gauge although there is data for 16g, 20, 28 and 410 so I am guessing a similar burn rate to Vectan A1 anyone used this in the good old days?
