The sripple7 powder is very special only grows in Western Pa. lol.. I have been using 100 gr by vol of both. My powder for hunting will be Triple 7. Groups of around one and a quarter inch are common with both powder .I have one target thats just used for cold barrel shots with 5 holes in it about 1 1/4 inch spread. I have varied the powder charge up and down 10 gr but see little diff. I have no pics so you will need to take my word...lol I fish also.
