I can't think of any European company that loads that heavy of a 20ga load and from my experience it really isn't needed. An ounce of lead shot is plenty it is my go-to for in 12, 16.and.20ga for birds. High steel 2 3/4 cases even get stuck in my reloader.

I think your problem is heavier loads and high steel hulls.

I shoot a BRNO 305 12/5.6x52R with a set of 12/12 skeet barrels.

After the first shot the rest are just noise.
