Harold , as suggested before , If it were me I would use the 1oz data and load 7/8 oz using a filler if needed and give it a try . If loading in a 2 1/2 hull and using the sg 16 wad I doubt that you will need a filler . I have seen at least one ,... 3/4oz load using longshot on the LPG it stated it was very constant , it should be very low pressure though , so may not be good for cold weather . load up a few and give it a try .
