I recently picked up a 1929 LC Smith FW 16 gauge. it's been restored by Buck Hamlin. The seller had the chambers lengthened and it was given a thumbs up Mr. Hamlin regarding the barrel thickness. All that said I'm planning on feeding it RST loads and I'm wondering which specific RST load would work out best for fair weather pheasants. It's choked IC/Mod and I was planning on buying 6 shot. Any personal favorites?
