Thanks to those who chimed in to help me select a good optic for the 375 Ruger back in this thread:
I ended up selecting the VX-III in a 1.75 -6x with a custom Gun Metal finish from the Leupold custom shop. It is a fair bit darker than the matte finish on the rings / rest of the rifle, but it does look great on the gun and I think it was worth the wait. They quoted 14 weeks to allow for corrections to be made if the finish didn't come out correctly the first time.
After several conversations with Leupold technical support, it became clear the scope is anodized out-of-house for the the "Leupold Custom Shop." This is less preferable to having things done in house IMHO, but it does look fantistic and has no flaws. I assume it will be as durable as one of their standard finishes.
All right, photos done uploading... sorry for the quality, taking pictures of a rifle was harder than I imagined. I hope you enjoy!
The other rifle is an M77 Mk II in .243 Winchester.
I have the 375 shooting 1-1.5" groups at 100 yards after one trip to the range with the scope mounted - I did shoot it open sights for a bit first. The low 1.75x is a great "replacement" for open sights.
My trip to the Sitka area is coming up at the end of this month. I'll post any pictures of wildlife that succumbs to this new setup after the trip!
