Looking for some wisdom on 20 gauge slug loads
I reload a few types of slugs for my 12 gauge, but I just bought some reloading gear for my 20 gauge and figured it would be fun to load slugs.
What I am finding is that there is very little in the way of slug data for 20 the 20 gauge.
I'd like to use wad slugs as I am using a gas operated shotgun (saiga 20) and the gas vents are a pain to clean lead out of.
What I have is:
Lee .575 RB (285 gr.)
Lee Minie .575 (470 gr.)
Lyman Sabot .576 (350 gr.)
I don't have load data for the lees as they are intended for muzzle loaders, but they are the same size as the lyman.
What I'd like to know is how much constriction is safe. The wads I have measure .03 thick on the petals (give or take .002) so the combined thickness with the slug is .635 and my barrel at the choke is .615. As I understand it, shot actually generates a lot of constriction, is this correct?
Would a shot load of a similar weight be a logical starting point? Or are these totally different items?
Looking for load recipes for 20ga slugs
I am trying to load some 20 gauge slugs but I have not been ablt to find any load data any where. I am using the foster slug from a Lyman mold, Winchester hulls, Winchester 209 primer. Powder will be what ever works, If I need to buy some different powder then so be it. Also, do I need a special wad? I tried using the normal wad but with the fingers it is to thick. I have expermented by cutting off the fingers and just using the base of the wad. Any and all help will be greatly appreciated.
