Good to hear Kent has some light, low pressure loads. A lot of the Brit stuff is good, but what you often see are hunting loads rather than target loads.
If you need low pressure loads, reloading is also an excellent option. Especially in 12ga, there really isn't much reason to reload unless it's to reduce pressure and/or put together light loads. Pretty much the same story with 20's. The only reason I reload 20's these days is because I really like shooting 3/4 oz. And with a decent hull (I reload mainly Rem Gun Clubs) and the Claybuster 3/4 oz wad, you can make yourself some nice, light target loads.
