In the 12 bore
Practice for clays ~ Just about anything in 28 gram down to 21 gram
Competition ~ almost exclusively RC4 Champion Excellence 24 gram 7.5, occassionally go to 28 gram for FITASC or something silly on a sporting layout
On the odd occassion I use it game shooting RC SIPE 6's or 5's on really tall pheasants.
For pigeoning etc, the odds and ends of 5's & 6's I have gathered up through the year. My favourite for windless days roost shooting have got to be RC 4 Piccione 36gram 6's or RC JK6 in the same load through skeet choke. That pull's em' down from a way up!
In the 20 bore
General clays and practice ~ anything 24 gram downwards but I prefer Hull Pro Twenty 21 gram.
Game RC SIPE 26 gram 6's
In the 28 bore
RC 28 21 gram 6's
Bornaghi semi-mag 24 gram 6's
Hull VIP 24 gram 5's
For the ducks, I hand load 22grams of ITM 5's over CSB0 and that does the trick.
