Author Topic: Darn Vertical Stringing (Read 1418 times)

Got the 17 FB ready for Coyotes today, sighted in at 100 yards and put the last five shots down range to see how it would group. If I could get rid of the vertical stringing on this gun it would give me some fairly good groups, Any suggestions that are not in the FAQ's? Larry

I am sort of simi-serious, if I could get rid of the vertical component I would have a nice .2 inch five shot 100 yard group. Larry

Don't know what to tell you Larry. I do know one thing for certain though, that is a darn nice group and I am sure beyond my capabilities.

Just remember to aim lower after that first shot.

Try using a quarter, it will look more impressive.

Nice shooting.

From a bench rest point of view, try modifying the powder charge just a bit, just a whisker on the powder measure can stop the vertical string. By the way do you weigh every charge or throw with a measure? Every bench shooter that I know throws a charge instead of weighing them. Most of them cannot even tell you how much their favorite sub .0010 group weighs but can tell you exactly where the measure is set .
For the record most of the VERY expensive rifles around would be hard pressed to do as good a job as your Handi!!!!!!!
Excellent shooting and craftsmanship !!!!!!!!!

I weigh the charges, not that I think it is better but I just don't have a powder dispenser and I do have a scales. I am kind of thinking this is just something that cannot be totally gotten rid of in any of the break open rifles no matter what you do with them. It also could be that I just changed where the bags hit the forearm by a quarter inch, but it sure would have been fun to get the same group vertically as it is horizontal. I have a Savage 10 in 17 Remington that will do almost as well, no vertical stringing but about a half inch group from a cold clean barrel. It is fun when things come together. Larry

Well larry i believe it may be hopeless

It's quite obvious, you didn't use enough SUPER GLUE when you fastened the barrel to the stub!

And another thing... switch to oyster crackers instead of dimes and your stringing problem will disappear immediately!:)

Vertical stringing My BUTT!
That one is a FLYER!

mcwoodduck: You are probably right, it's most likely the one that had the neck split. Larry

mitchell · « **Reply #16 on:** October 14, 2009, 05:38:15 PM »

flyer or not you still have vertical stringing, great groups and i dont know if they will get much better then that, but you and i are just alike we can never settle for almost perfect i would go to your shooting style and stocks. you need to make sure the gun is recoiling straight back everything .some kind of factory rest that your gun fits snug but not tightly and do not go with a lead sled or anything like it . any rest with a back at the rear end will make your groups vertical string the abrupt stop when firing makes you muzzle kick up , same thing when shooting from your shoulder . try using the free recoil method of firing.

not saying this has to be the reason your getting the groups you are just something to look at.

Damn fine group, Larry. Shows your craftsmanship at work. That and the fact you ain't to bad a shot yourself.

Damn fine shooting. It says a lot about the rifle, the loads and the rifleman. It could be many different things, Larry. I think it might have some thing to do with lock up consistency, but it might also have to do with powder weight or even some other factor. The 17 FB has a fairly small capacity case and even .1 grain can make a difference. I am not talking about variance I am talking about increasing or decreasing the powder charge by that much. When you get groups down that small, it is important that every thing is exactly the same from shot to shot, including barrel harmonics and lock up. That is very good shooting - that most guys would be thrilled with. I know the feeling that when you get a good group - is there some thing that I could do better. When you get down that small, it takes paying close attention to details. That is when the bench rest crowd's work becomes important. Not going from 1" to 3/4". Have you weighed and sorted your cases, uniformed the primer pockets, de-flashed the primer holes, weighed bullets - the list can go on and on. Have you tried different primers that may or may not be a solution - a different primer can help or hurt. While I prefer Remington 7 1/2 primers, most of the Benchrest guys like the CCI BR4 or Federal 205M primers. Just keep in mind - It is very difficult to decrease groups as small as yours because it takes very, very little difference between shots to open a perfect 1 hole group to one that looks like yours (which isn't any thing to sneeze at). Good Luck and Good Shooting

Great Shooting

Best be careful BHO may have the feds after you for that one.

Etced · « **Reply #21 on:** October 15, 2009, 02:38:50 AM »

I would pick out 5 cases that weigh the same, reload them and try again.

I would start with the thing that is the easiest to check and hardest to fix...shooting position/bench set-up. It amazes some of my sniper students how much the little things like a shirt collar getting under the gunstock for 1 shot can change things. We all know about the front bag placement here. Do you use a rear bag? Sissy pad? Are you craning your neck with your set-up?

mrbgt · « **Reply #23 on:** October 15, 2009, 04:47:34 AM »

try a barrel ''de- resonator'' ? Is that little dent on top the 5th shot? Stll a nice group !
