Blue Dot Shotshell Load

[mswestfall]

Does anyone have a reloading book that shows this 12 gauge load?

Winchester AA (two piece) Hull (can substitute a Nitro or STS)
Blue Dot Powder (MEC 36 bushing) about 33.5 gr.
Winchester WAA12R Wad
Winchester 209 Primer
1 1/4 oz of lead (no buffer)

I've found the same shell with a MEC 37 and 38 bushing at about 1,250 and 1,330 fps respectively. But I hear that the 36 bushing will be about 1,175-1,180 fps with 8,300 PSI; a very soft kicking 1 1/4 oz load.

I know that asking about the bushing rather than the powder weight is a little backwards but I'm just trying to find a manual that lists the above load.

I'm interested in anything with a powder weight within a half a grain.

Please include the manual name and date. THANKS!

Lyman 4th Edition Shotshell manual: Win AA compression form hull 1 1/4oz.
Blue Dot--36.0 grains--Win 209 primer--Win WAA12R--1254fps--8300 lup
No loads using Blue Dot and WAA12R wads in Remington STS-Premier hulls with 1 1/4oz of shot. They do list 1 3/8 and 1 1/2 oz loads with BD and WAA12R wads with Rem hulls. The hulls listed in the 4th Edition Lyman Manual are the old Win AA one piece hulls but I understand the new Win hulls use the same load data. I guess you've seen the Alliant Powder data on their web site.
Just for comparison:
Remington Premier RTL hull;
1 3/8 oz shot--Blue Dot 33.0 grains--Win 209--WAA12R wad--1219fps--11,100 lup
1 1/2 oz shot--BD--29.5--Win 209--WAA12R--1117fps--10,700 lup
Now if you're talking about the Winchester polyformed hull with a high paper base wad or the polyformed hull with a plastic base wad sold as dove and quail, rabbit and squirrel. or pheasant hulls, Lyman shows no data for 1 1/4 oz loads using Blue Dot and the WAA12R wad.
Lyman has a new 5th edition out now. Blue Dot shotshell loads recommend wad pressure on the powder for best ballistics.

mswestfall: This is the closest I could find, and I'm not current on effects of reducing this charge, but here you are.

Okay Thanks,

I asked the guy again today. He said he is loading with a 36 (MEC) bushing. Without finding a published load with 33.5-33.8 gr of Blue Dot. I'm gonna load the 35-37 gr load.

Thanks for the effort.
