> The Colossus weighs in at 8.45lb for a 10.5x13.125 inch large, but per Buff's measurements in pic related the sizing is nominal (great!) and actual measured is 9.75x11.625".
I've checked this and that seems like a copypasta mistake in the table.
The measurements are drawn on the plate in the video and they're 10.5x13.15". Then if you compare it to the 10.25x12.25" Protech X-Cal and the 9.5x11.4" 4SAS4, over the same clay drop-test briefcase, the Colossus Size L is much larger than the 4SAS4 and taller and slightly wider than the X-Cal. (The scale in the screenshots is messed up. Look at the plates vs. visible clay and the size of the briefcase behind them.)

I don't think this is it. It's 100x likely that the "surrogate" was botched. It's gotta be super tough, maybe impossible, to homebrew a surrogate for a really advanced tungsten round like that.
