Hushpower and steel shot

[3175darren 1,100]

Hi I know this topic will be done to death , around normal shotguns , and maybe I have missed it about the smaller stuff, 

I know calibers below 243 will not be effected in rifles , at least there’s some sense come through , 

I have,  and use 2 hushpower mossbergs one in 410 and one in 20 gauge , I know the 410 has a full choke , and as yet I have seen no 410 cartridges loaded with steel , and in truth I hope they see sense and don’t force it onto small shotgun calibres , 

my 20 gauge has a full choke and I am reliably informed , that that choke can go down to half , without affecting the moderator , I use these two guns a lot and have just picked up a farm that has some major vermin issues mainly crow pigeon , and although I do not want to move these guns to steel shot , does anyone know what my options are ?? I really do not want to sell them , as they are a mainstay of mine . 
 

any advice would be welcome ,
