That's A No Brainer
Or, at least for me it is.
If you have ever watched me shoot, I do not use the actions ramp and coned bolt the wat most shooters do.
When I first started shooting Benchrest, I had a 40x. This required "flipping" the loaded round into the chamber rather than laying it on the ramp and letting the bolt push it in.
I never got out of the habit. I still, whether shooting fast or slow, flip that round all the way in. It is just an instinctive thing now. I don't think it slows me down at all.
So, I will take the tuner. Those that do not use a tuner will naturally say that it is of no consequence, but since I have pretty well proven, to myself, at least, the worth of a good tuner design. I think I will continue to use mine as I have for the past 3 1/2 years.
Dave is right, you cannot make a barrel shoot any "better" with a tuner than with conventional tuning methods. It is simply another way to arrive at the same place.
The only advantage the tuner offers, (in my opinion), is the ability to change the tune instantly, at the line, if the need arises. But that is another discussion.,.........jackie
