Hi Grant, I've been mulling this idea over for a week and need help to put finishing touches on this idea before attempting it. I purchased three marauders, Two in .22 and one in.177, One of the .22's I want to try converting to .25 cal. I have the barrel, An LW and have dimensioned the breech for machining, I have a machine shop but very seldom spend a lot of time making parts, I prefer to shoot them not make them. Question: Since you have a marauder in .22 could the clip be modified by enlarging the slots on the rotary pellet indexer and face plate slot to accept the .25's? I'm waiting on additional clips to arrive before disassembling one. I think this would be a great conversion on an already great gun. Your input would be appreciated!! Regards,
