Glenn,My remark was not directed at the experienced, but rather at someone at the beginning, who may not even have the basics down yet. Of course we all experiment, but for those experiments to be productive we need to know how to tune and read flags and no beginner really has that down pat at...

I have started a couple of fellows out with their 6PPCs, with good success. Invariably they seem to think that their next move should be to find the magic bullet, this after shooting a group in the teens with the readily available bullet that I had them start with. What they don't seem to get is...

Thanks. Hopefully your rundown and mention of the trigger issue reinforces my earlier post. People often try to employ techniques that their equipment is not suitable for, not the regular competitors, but those who are working up to it. The Savages can do a good job on something like F Class...

Jim, Did he say what kind of shooting he was doing? If he did, I overlooked that detail. In the short range game, Ocock shot himself into the hall of fame with a very soft rear bag, squeezing and holding the rifle. I agree short and long range are very different. Do you shoulder your rifle when...

I do not see any indication of how you are handling the rifle as you shoot it in your posts. If you are trying to shoot free recoil with that rifle you will continue to have problems because the trigger is not light enough and there is a LOT of barrel in front of your front sand bag. So, how are...

On the subject of tuner weight, a fellow that I know, who shoots short range group reported that while his Beggs tuner worked fine with his LV rifle that it did not seem to get much response on his HV that has a heavier contour, stiffer barrel. To remedy that situation he added a third disk and...

If you look at Vaughn's work, the position of the center of mass relative to the axis of thrust gets into the muzzle rise amplitude situation pretty strongly, so stock design is another significant variable.

Cortina's tuner weighs 6 oz. He just messaged me with that.

I just messaged him the question on Facebook, and I will get back to you with his answer.

The weight is the same contour as the barrel behind it. If you look, there is a parting line and in front of that the outer part is threaded onto threads cut some distance back from the muzzle. There is a smaller "tuner tenon at the muzzle end of the barrel. The point is that just moving that...

On the subject of heavier rifles, let me point to varmint Al's work on tuners. He showed that adding the weight of a tuner was one of several ways to move the point of bullet exit from the muzzle to the left side of the muzzle rise curve. There were a couple of other ways that he demonstrated...

In short range benchrest, tuners are about being able to make small adjustment at times when making a load adjustment would be inconvenient (like in the middle of a match) and broadening nodes. There are other things that influence node width. Friends that have a lot of experience with both 133...

Al, When you busted your lip with the Vaughn, the effect was immediate and obvious, not so much with dangerous chemicals and after the effects have finally showed up, a Band Aid or stitches generally won't fix it. One of the advantages of education is that it allows us to understand and deal...

So Calfee is wrong about setting his tuners once and then not moving them? I understand that he has done pretty well selling rimfire rifles with tuners. Do you know anyone that claims that he can do that with a CF tuner? Yes they both change tune when you move the weight. Beyond that, if you...

One thing that can escape us is that portable bench tops are subjected to twisting forces. IMO the best way to deal with this is to use some sort of stressed skin construction with a grid like spacer between and solid material around the edge and where legs would be mounted.

My portable bench has pipe legs that screw off, and although the thought was a good one at the time, what I found out after using it for a while was that since I was hauling it with a pickup that had a tall enough shell, that I could simply leave the legs in place, haul it upside down, slide it...

I have some experience building benches, both permanent and portable. It has been my observation that if you have an adjustable stool that a short man can be more comfortable at a tall bench than a tall man will be at a short bench. The benches at two local clubs are 34" and I would not build...

I have played with tuners some, several designs. One thing that I would like to mention is that sometimes we get wrapped up in theory and that can distract us from the simple direct stuff. First of all the most basic information is ...tuners work. The second thing is that it is easy to confuse...

Have any of you read the article that I mentioned in my previous post? Since the magazine is no longer in business I suppose that I could post the article if you have not. Unless someone thinks there would be a problem with that.

Of course that would be entirely up to the person doing the asking. This sort of reminds me of someone asking how many guns a person needs to own.
