It's not worth my time to show you the proof. Do some searching around and I assure you will see pictures posted on the internet of guys hold a bolt handle in one hand and the remaining part of the bolt in the other.
Also keep in mind, data rules the roost. Just because it hasn't happened to you doesn't mean it won't. Too many variables to consider.
Let me not even get into some of the other issues I've had with Remington Shotguns.
As for the comments on custom. That is the beauty of custom. You built it the way you want to. If I was a fan of the Remington platform, I'd go with a clone that is already pretty much perfect.
