"universal" shotgun loads 410, 20ga, and ???

[cpileri]

I saw some old posts bat universal shotgun loads. very cool.
the 410 is from our own turbo1889:

"13 grains is the universal load for 2400 powder in the 410-bore

~ Any hull
~ Any standard shot shell primer
~ No magnum primers (CCI-209M, Fed-209A, or Fiochi 617)
~ Any Wad
~ 7/16 to 1/2 oz. shot for 2-1/2" hulls
~ 5/8oz to 3/4oz shot for 3" hulls
~ Any lead, bismuth, or other soft shot
~ No steel shot, hevi-shot, or other hard shot
~ No buffered loads

Like all universal loading formulas some load combinations will be a slightly reduced load since the universal charge is calculated on the basis of the combination of components which will give the highest pressure level."


the 20ga I just found, so can anyone verify if its a good one?

"Any reloadable 20 gauge hull. Ones I've tried it on extensively include Fiocchi, Federal, Remington (all the variants) Winchester CF and Winchester/Western HS.

W209 primer
14.5 grains Unique
Claybuster 1078-20 wad
7/8 oz shot

Gives between 1145~1200 fps depending on which hull you use"


any others like these for any other gauges?
