I reckon there is a gap in the market for some powder 'tester pots'!?
When you start to load for a new calibre, you are faced with a whole host of powders which may, or may not suit your rifle. It is a lottery, and every rifle is different. To buy a whole 1 lb of powder to find that it doesn't suit is both wasteful and expensive. What if you could buy 4 x 4oz pots of different powders to try? 1 lb + 7000 grains. 7000 divided by 4 = 1750 grains. Based on a 50 grain load, a 4oz pot would give you 35 rounds which should be more than enough to establish whether they suit or not.
Good idea - or am I just talking bollox after several cans of Abbot Ale?
RFD's - make it so!
