I have a 1902 (PGCA Lettered) PH 12- 30" DT No. 2 frame- unaltered and with the later bolt tool steel wear plate- I shoot 2 & 3/4" dram Rem Green RST's in it for pigeons- and it is a pleasure to shoot. I also have shot 2.5 RST 1 oz. orange hulls in it- ditto- And if it wasn't for the Feds and steel or non-tox shot for webfeets, I'd use it for ducks as well-So enjoy your 16 Grade C- great bird gun indeed.
