Remington R 16 vs SP 16

[Researcher]

According to the 1977 Remington Shotshell & Metallic Cartridge Component catalog the R 16 is for 1 ounce loads and the SP 16 is for 1 1/8 ounce loads.

FWIW in the earlier days the 1 ounce wad was W 29932 and the 1 1/8 ounce wad W 29934.

So, a .125 filler wad in the SP 16 shot cup would make it close to being the equivalent of the RP 16, right???

Forgot to give Researcher a big 'ol thank you for the great info. This proves my assumption that someone on this forum has the answer to almost any shotgun question and that's nice to have such a resource a finger click away.

There are knockoffs on the market for the one ounce 16 gauge wad. Downrange gave me a few bags to try. They are very nice wads. I'll probably find some when I move my loading room. Everything is packed away right now. I also have more than a lifetime supply of Remington 1 ounce Game Loads.
