Years ago i was working up some turkey loads with hard number 5 shot.
I was using 700x and after loading up several to test went to mu friends house.
I shot the first loads with mu 870 rem.and it almost shucked the empty out of the gun.
They did kick more than some we fired that day.
My friend had a Marlin goose gun and said his would handle them just fine.

Well after the first shot the empty would not eject,seems that the chamber had swelled some what.
We dug it out with a knife and did some measuring and it was swelled a lot.

Here is the thing,he got ahold of the maker and asked for a return number and told them what the problem was.

Guess what they did not charge him for fixing it but he did try to pay for the repairs.
Just who's fault was it that the shotgun ceased to function the makers or us.
It's not that hard for folks to take responsibility for their actions but it seems much easier to get the other guy to pay up.

It seems that we are all doomed.
