I tried some 16 ga x 1/2" fiber wads (untreated) under a shot column in the 10 ga. w/ 1 1/4 oz They didn't "poof" but didn't sound and feel like a full charge round and burned very dirty. Same fiber wad IN the shot cup worked well, got me the same shot height for crimp, burned much cleaner. Have to think the result was a very low pressure round, too low to fully burn the powder. Shot both outta my Ithaca Mag 10 for test purposes, neither would fully operate mechanism, no surprise there.

All the 1100 fps RST loads I have shot are extremely dirty however the 1250fps bismuth load was alot cleaner. Not sure what the pressure difference would be between a 1 1/4 oz at 1100 vs 1250 fps. Their bismuth load was listed as 1 3/8oz but when they started running out of supplies they went to a 1 1/4 which is what I have. I need to look at the load data and see if theres a handload in there that is similar to that.
