I have a Axe/Rossi .45 in mine..a Prather 230 puts me at bout 45...I am running a self modded 245 now puttn me at 55-57...a 240 might work well..if it loads up a lil might try a small barr cut..have a x455 modded I haven't tried yet..because of the filler they use where the stuffing tube comes out of the bottom it limits you on strut height...I cut mine out and reglassecd to give me a lil more..here's a vid with the 245 on it..a lil windy that day and sucks with out a camera man[youtube]http://www.youtube.com/watch?v=WVUH7...feature=relmfu [/youtube]
