Absolutely. I'm always amazed at how much force a reloading press generates. Even a bench weighing hundreds of pounds can be significantly "nudged" by a reloading press.
The weak point in my new bench is the pine top. Had some very long pine boards that were used as pallet reinforcement for some tongue and groove pine that went into our new home. Wanted to make use of the pine for the benchtop, but it wasn't stiff enough to handle the press forces without deflecting during the downstroke; I had to add an extra 2x4 brace underneath, and additional screws thru the pine where my primary station is located.
