I have a #1 in 450 3 1/4" NE.  From the factory, it came in at about  7 1/2 lbs.  Ridiculous and to add insult to injury, it came with typical worthless Ruger recoil pad.  I spoke with the Ruger reps at the 2020 DSC Convention about these issues.  They don't seem to get it.  I give Ruger credit for some great offerings over the years; however, the "devil is always in the details."  I lit my #1 off with one round of Hornady 500gr solids - don't need that abuse, and I am hardly a virgin when it comes to lighting off the big boys, including 7 and 8 bore muzzleloaders and an recently acquired factory 500 A-Square.  I installed a mercury recoil reducer in the butt stock (no tools required) and an appropriately named "Limbsaver" pad.
