"...the first American-made straight pull..." Nope.
Aluminum receiver...nuff said.
Ambidextrous bolt: impressive, and so is the ball-bearings-in-a-groove locking mechanism. I have to wonder about the very small contact area that each ball would have with the wall of the groove however. Even with as many balls as can be packed in that diameter, the total bearing surface is still very small, unless each sits in a matching recess, but the graphics I saw suggest otherwise. Same system as Heym apparently, for a lot less money.
I wonder how the Impulse would do with a case full of pistol powder? We know how the 1910 Ross action does, and it's only 110 years old!"...a lot straight pulls don't come in magnum calibres because their technology can't handle the pressure..."
And in a similar vein, it seems Merkel is recycling the Ross interrupted thread bolt head.
