SMOKELESS 16 gauge 2 1/2" low pressure

[6pt-Sika]

I'm intrested in a low pressure 2 1/2" 16 gauge load as well .

However I'm going to be using RST hulls and trimmed Federal High brass hulls . Also will use them with the Claybuster knock off of the WAA16 wad . Primers on hand are CCI209's but I may get some WIN 209's as well . Will be using 1 ounce or 7/8's ounce shot in this one .

Now then what powder and charge does anyone recommend ?

So then hulls used will be ,
RST
Federal high brass trimmed

Wad ,
Claybuster knock off of the WAA16

Primers used ,
CCI209
WIN209

Now what powder to use and charge weights to stay in the under 7,000 range ?
