Sonoran Desert Institute – 416R Stainless Steel – Ruger M77 Mk II All Weather .338 Winchester Magnum

Sonoran Desert Institute – 416R Stainless Steel – Ruger M77 Mk II All Weather .338 Winchester Magnum

My submission for Sonoran Desert Institute FTT 231 Week 2 Assignment. I have done a quick rundown on the basics of 416R Stainless steel and it’s properties.

I forgot to mention in the video that while Ruger does use some cast parts, the barrel is actually cold hammer forged. In fact this model year of rifle 1991 was the first year Ruger began using cold hammer forging according to their website.
