.410 semi auto loads

I have a Remington 100 .410 semi auto which is a great gun. I am also in the UK. The problem I have is that I need to use fibre wad ammo in some of the places I shoot. However ALL the bought fibre wad ammo I use in the .410 semi auto has the same results. Usually the primer comes out on firing and clogs the works up AND the spent cartridge remains in the breach often being ripped by the extractor claw instead of ejecting. The only cartridge I can get here in the UK to work satisfactorily is Fiocchi 19.5gramme plaswads. I have started reloading so that I can use the gun with fibre wads.
I was wondering if anyone in the USA was reloading .410 fibre wads for such a gun and if so what their "recipe" is in terms of shotshell, primer and powder.
I may be confined to using this gun on ranges where plaswads are OK.

.410 cartridges

Many thanks for the info. You are on the right track because I have been experimenting with the charges and shot content of my cartridges.
Bizarley the combination which works best is 10grains of HD110 and 19.5 grammes of lead. I conclude that the inertia of larger loads (21gms) allows the cartridge base to expand and then the extractor cannot do its work so rips the base since that is clearly the weakest point. I did clean the chamber as far as I could and that worked but pretty soon clogged again. Believe it or not the gun cycles fine with just the 10grains something I tried not expecting it to work and was staggered when it did. I need to find a tool that I can use to clean the chamber with after every shoot. Also I have not had the recoil spring out since I bought the gun so that is in for a clean too since it may be delaying the movement of the action to the rear just that split second too long.
