My wife got me an A5 Browning 3 1/2 for Christmas. She has really been enjoying shooting clays with me but I'm having trouble finding a shell that will cycle. I've cleaned/lubed the gun really well and tried a couple different shells in it but not much luck so far. I know the manual says it requires a 1 1/8 oz, but which dram, fps should I have the best luck with? Thanks for all the help.
