Either theTorchCam™ action produced a dry firing pin with the model inside the store - or the breechplug thread were tapped a fraction-too-deep. That ML should of fired using Winchester 209 primers. That particular Remington model was product-tested exclusively with Remington Kleanbore 209 primers. If using any other 209 brand inside that store model that wouldn't fire Winchester 209s & perhaps others that were built prior and afterwards, it may be necessary to keep the firing pin wellclean & oiled (and/or) slightly turn the breechplug an 1/8th to 1/4 turn counter-clockwise (loosen)after snugging the breechplug during installation.

This may rectify any misfire problems. Like I said, it could be a dry firing pin -- fractional length differences between different brands of 209 primers - also a manufacturing design flaw that will get "tweaked/corrected" since the ML Genesis is so new.

That's why I never buy a new design ML in the first year or two. For instance: The CVA Optima underwent several "tweaks/corrections" in an 18 month time frame afterentering the marketplace. I'm sure this slight problem will get corrected too. But it's not uncommon for that firing pin to be either dry or binding when brand new. Not uncommon to have a breechplug thread design that's sensitive to other primer brands.

It'll all come-out in the wash... so-to-speak! Not a knock against the new Genesis. May turn out to be basically design-defect free... unlike the Optima and many others - including the 1-20" twist failures T/C had with the Omega/Encores early-on.
