Only if I find I need to load more than 400 per month. So far I only need to load 357 pistol. My rifles are .22, 7.62x39 and 7.62x54R so surplus or factory ammo covers those needs very well.
Good eye on the door, I didn't notice that. the way the legs are attached may end up failing when good pressure is applied also. Hope not for you though.
I bolted to 1" hard wood on top n bottom. At this time I only do 357 mag strait wall so I should be good to go. The owner of the house before me made the bench and I was too lazy to install a real wood bench. But if it does break it will be another project on the list.
I have that same press. Lots of torque happening when cycling even with the straight cases. With the extra wood installed you should be fine, just keep an eye on the top to make sure it isn't cracking around the added wood.
