What does it mean when your shots start stringing vertically? The knowledgeable guys on this thread refer to it all the time. What causes it, and what do you do to eliminate it and make those groups round?

Benchrest Hall of Fame inductee Speedy Gonzalez has you question cover with an explanation of what [vertical] is, a great picture of this infection and it's related cousin [horizontal], and cures. Travel here for the show: http://www.6mmbr.com/verticaltips.html. Art :)

Gil, keep in mind that what we deal with Benchrest Rifles. We assume that everything concerning the Rifle is mechanically sound. That includes the bedding, the firing pin assembly, scope, mounts, chamber job, etc.

Normally, if you are getting verticle stringing in a Benchrest Rifle, what that means is your load is a little light for the load window you are shooting in. Under those circumstances, you can go up a tad, and the Rifle starts shooting. Or, at least you hope it does:D.

I personally think that things such as bench technique, bag set-up, and the such are over rated. The single most important factor in producing winning aggs is a well tuned Rifle. It is amazing how all of the other things just seem to fall into line when you hit a good tune. Great tuned Rifle make good shooters.

I catch a lot of flack from fellow shooters because I have always said that at any given match, as many as 75 percent of the Rifles at the line are not an a competitive tune. All you have to do is look at the targets. Shooters will come up with every excuse in the World as to why they are doing poorly except wanting to admitt that the Rifle simply is not working. The reason they do not want to address the tune issue is because it is one of the most difficult items to stay atop of.

We here shooters on this Forum say things like, "the Rifle shoots better than I do". Well, that's not neccessarilly so. I have been to the line many times where the Rifle was simply not working, and try as you do, all it will do is what it will do. What separates Benchrest from the vast majority of the other shooting Disciplines is the simple fact that you are only as good as the Rifle you are shooting.

Remember, this game is really about three things. Barrels, Bullets, and Tuning. You get those three right, and every thing else seems to fall into place.

Speedy's article over on 6mmbr.com is a fine article. Speedy is a hall of fame shooter. But, in my opinion, the very first thing he should have written in that article, in big bold letters, is TUNE IT.

If the Rifle is not working, all of that other stuff is simply window dressing........jackie

Jackie's comments as always are right on and pertinent! Speedy's comments in the Load Tuning section, further down the page, especially its first sentence, should have been repositioned to begin his article. :)

Greetings Jackie. Basically/briefly what do you mean by a "Tuned" rifle"? Thanx.

Cheers,

Mark

I am not sure how familiar you are with Benchrest, but we shoot at such a high level of precision, that the Rifle is very subseptable to fluctuations in the weather conditions, which can change the burn rate of the powder, (or something), enough to where the Rifle is no longer competitive.

Staying on top of the "Tune" is one of the most difficult aspects of Competitive Benchrest.

Keep in mind, what we consider "out of tune" would probably not even be of concern to 95 percent of other shooting Disciplines.......jackie

Oh come on, don't put that load on him. Everyone has the right and duty to screw up occasionally and if you deny it to them, they will explode. That's a scientific fact!

Greetings Jackie. I'm familiar w/Benchrest but I wasn't sure if you meant something physical such as ensuring all your nuts and bolts were torqued tight, or using a physical device such as a Tuner like in .22 Benchrest. I think what you're saying then is that every component part (Ammo, rifle) must be tweaked to perfection (Or nearly so) so as to be In Tune.

Cheers,

Mark

Since I am sitting here watching the Daytona 500, I can make a good analogy.

You see drivers running up front, and then the car will develop just a little push, or get a little loose or tight, and the car goes straight backwards. All the driving skill in the world can't make a car that is off on the setup get around the track in a competitive manner.

It is the same with a Benchrest Rifle. If it is locked into a .300 tune, try as you will, that is all it will do........jackie
