Title: Reasonably Light load for 12GA
Post by: Black River Smith on September 03, 2017, 03:50:47 PM
Could anyone suggest a good reasonable light (feather-light) load for 1 oz -7 1/2 or 9 - 12GA??

Please list the powder and amount range that you would use for a feather light to light load.

Also does anyone have a light load suggestion using IMR - PB powder?

These loads are to be used in a new modern 1887 Win lever shotgun that I am making shorter 2 1/2 paper shells for because they cycle better than standard 2 3/4.  Circle fly wads will be used to regulate heights.

Thanks

Oh GOODY!!  40Gr APP 2f with a 1 ounce Payload.  I do shoot reclaimed shot and DO recommend a shot cup.

I brew my own too. My W-W ( plastic shells) 12 ga loads are a #381 powder bushing with an aftermarket CB0125 pink wad 3/4 oz #9 shot or a #408 powder bushing with a WW grey wad 3/4 oz #9 shot. Clay Dot powder used in both. I increased the powder because I was having problems with my cut bbl model 12 trenchgun build not taking down oblique targets. In sgs with a choke or straight on targets the lighter one works fine. They feel like WW Featherlights. Can't help you with the short shell though and of course that changes everything.

You have to look at the whole system. But as Stu kettle says, a lighter shot load has the greatest effect in lowering recoil.

The RULE in loading shot shells with smokeless is NEVER VARY FROM A PUBLISHED RECIPE. So look through the reloading data bases for what you want.

Having said that, here is a formula that I have used in trap shooting for years, and carried over to CAS until I went to the Darkside;
-  Win A-A hulls (Old style- 'cause I have a bunch!)    ( R-P RST, Nitro27 or Gunclub are also very durable, and are close to the same capacity.)
- 209 primers of most sorts; - But see the rule in CAPS. above.
- 16 - 17 grains of Red Dot or better still Green Dot.
- AA or Claybuster pink wads for 1 to 1 1/16 oz loads, or grey wads for 7/8 oz.

There are many similar formulas in the data bases, and especially a wide variety of wads. You will find that your game, or clays, or knockdowns will not miss all that expensive shot you will be saving.

Imo, Clays, Clay Dot or Red Dot in a light sg load are somewhat the same. However Blue Dot is temperature sensitive and will be problematic in cold temps. Was given an old unopened can which I built sg loads with. When the temperature dropped I started having weak loads and wads not leaving the bbl.

Thanks Prof Marvel; I didn't realize I was that wise!
