Horizontal stringing ?

[corning]

How did this morph into a discussion about vertical stringing? The OP was asking, primarily, about HORIZONTAL stringing.

Question(s) to OP...

1) Bench, F-TR, F-open, or sling?
2) Bolt or semi-auto?

I am sorry if this info was included, and I missed it.

I added more sand to the ears of my rear bag and it cut my horizontal stringing in half

Bench rest shooting with 69 gr SMK's in a 223 24" 1/8 twist. Groups at 300 yds about 1 1/4 vertical by 2 3/4 horizontal but they can vary more or less. After reading some of the replies I can see it is probably me causing it. It doesn't seem to be wind as it happens when there is no wind. Is seating depth a possibility ?

Never witnessed this,and I shoot down to about 30 below zero . Who in AK is claiming this,benchrest folks ? That is an interesting concept .

Frank Gali and Mark (Marc?; don't recall his last name) - Marine Scout Sniper guys that run a class up there.

Shoot the numbers through JBM. A quick look through my phone shows 2.9” drift with a full value 3 MPH wind at 2850. It’s not exactly a slippery BR bullet and 3mph isn’t much. I’d definitely rule out cheek and shoulder pressure. And yes, revisit seating as well.

Everyday Sniper podcast. It is on Podbean. Not sure about other platforms. I want to say the first time they talk about it is in the early episodes, but it comes up every once in a while.

Horizontal stringing is very common. You just have to know your gun and conditions to know its the tune. It seems to be more common/obvious in larger calibers. Seating depth will usually fix it. Make sure your cheek is not on the rifle too.

Guys up in AK have found that vertical split rings are causing vertical stringing.

Never seen any indication of such on the split rings I have used. As for the horizontal stringing, inconsistent rifle holding, canting and/or wind, most of the time.

Bedding depending on the type of stock and action. I once had a rifle that I missbedded and used a 3x5 card for a target. 4 shots cut the top edge of the card and the odd one was in the card. Group was essentially 2.8" X 0.4" something. Ripped the bedding out and rebedded with groups shrinking down to sub 0.8 level. '98 small ring mauser and 7x57. Mauser are odd to bed.

Also canting.

Are you shooting free recoil? I do, and find a very small amount of thumb pressure will throw a shot. Last weekend I put 4 of 5 at 100 yds into a group that measured .09" CTC and one at 9 o'clock that opened it to .5"

Very frustrating

Wobbly benches at a public range, neighbors with 300 WM and brakes blowing my headset off MAY be a factor.

.223, 69g lapua,Varget, BR 4, Criterion 26 in 8 twist. Wind freshening rapidly post frontal.

Thumb pressure does not equate free recoil.

Thanks, Alex. I think you just pointed to a more likely cause of my stringing experience. Not my thumb after all.
