My suggestion if you want to use the Kidd is find an ammo that does better.
I am going to ramble like a fool here. Let's roll with your 2 platforms, assuming that you got both rifles shooting extremely close in the accuracy department with equipment and ammo selection. And again, you perceive that the B14R is the better combo.
Over the course of a period of time, if you take both rifles out on every outing, will the Bergara be the winner every single outing? Factor in by the time you switch rifles for tests, the parameters may have changed and therefore not linear.
So if the task is to put 10 shots on a 8" plate at 300 in 90 seconds, in goofy winds, not only variable in speed, but a 30 degree switch in direction happening at a moments notice, you do not have wind flags, or the time to monitor the whole picture. In this scenario, all things equal, the semi auto may have a distinct advantage because of rate of fire, and I don't mean a mag dump, just quicker followups.
But on a calmer day, same stage, knowing you have a semi auto and the capability of dinging the plate rapidly, it may bite you because you failed to watch the plate movement on impacts. Fair amount of mental games here.
I have 2 Kidd's, identical 20" barrels, a Vudoo, and a Rim X that are my blasting rifles. So with ammo selections, at times one may shine quite a bit better than the rest, but mostly they are comparable to each other to 400 yards. Now if I shoot past 400 yards, I use the bolt guns just because of my mindset, that I am going to take a more precise shot with a bolt rifle.
So IME, what I claim in July, may be the exact opposite of my findings in August, failure to account for all the input all the time is how these conclusions are made on my end.
