Everything seems quite so I thought I would stir someone to wake up with a pic of my 357 Ruger #1.
This post is a long answer to a simple question. I'd say very accurate. Accuracy depends on the bullet-a no brainer flunked on my part. I had grabbed up some "go to" rounds from other Roberts rifle. It was terrible. This event happened after I first got the rifle. Cutting to the chase the throat is long. This long throat was no accidentHow accurate is the 257 Bob?
Check out the number of the rings your found with 90276. Go figure where the rear extension ring comes from.This looks to be the ring. The only extended ring on Rugers site. Blued and stainless, this link is the blued. Only comes in medium height, one inch scope tube. Up to 42mm objective.
The 90276 is one extended medium ring. Wonder what the number is for the front extended ring? Since Ruger's come with medium rings wonder why the extended ring comes one to a package?The part numbers are on the two listings I gave links for. 90276 for the extended ring, 90270 for the standard. These are the Ruger rings you posted about. You can order them on the website.
