Since you did ask on this Forum, I will give you a little heads up on what this Forum represents.
In the title of your initial post, you used the word benchrest with a minor "b". This is appropriate, because that is the sort of shooting that your set-up is suited for. That being, informal sessions at the range, among friends, seeing just how much accuracy you can ring out of your Rifle.
As was said, many clubs now offer a Factory Class, so shooters can get a taste of competition, without all of the so called "hassles" that tend to make many shy away from Registered, (sanctioned), competition.
When we refer to Benchrest on this Forum, what we are talking about is Benchrest with a capitol "B". This is all out competition with VERY specialized equipment, the competition being governed by one of two Sanctioning Bodies, The NBRSA or IBS.
As was mentioned, go and find a club in your area that has a class for Rifles such as you own. You will love the experience, and will probably get to see some real honest to goodness Benchrest Rifles, and Benchrest Shooters.
But be carefull. This is a very addictive game. Once you take that first hit, you will crave the 'high' that only comes from getting as close to perfection as you can........jackie
