And for me, waterline is a group with very low vertical.... ideally placed across the X ring but sometimes.... :-)

Jerry, so by your and Rocky's definition of waterline, you can have a group with no vertical at all low on the 6 ring and say that you held great waterline?

Like I said before, waterline is an imaginary horizontal line across the center of the target. You will often hear shooters say things like "...waterline 8" as opposed to a "vertical 8" when describing where their shot impacted on the target.

If I shot enough rds in the 6 ring to form anything resembling a group, I might be better off taking up golf :o

Unless the bullets are landing in the center (vertically) of the target, I am too busy figuring out why and dialing the elevation dial so I am.

If a load has a lot of vertical ie will not shoot "waterline" (or more then 1/2 min of vertical), there is no way to center that group. You will place shots high and low in random manner - vertical ping pong (also called a Train Wreck or ClusterF%*@)

Sooo... a load that will shoot waterline is one that has the mechanical accuracy to stitch a line across the target with as little vertical as possible. Just like what AZS shows with his very nice 223 loads. Remember, he is testing a load NOT shooting a relay for score. So position on target has little bearing.

Now that he KNOWS the load will shoot with little vertical, shots that trend high or low on his scored target simply require a scope adjustment to center on the "waterline" of the target.

But we all know this.... the symantics are getting in the way of the obvious.

As much as it pains me to (sort of) agree with Erik ;D

I'd say 'water line' as it applies to NRA HP score targets would generally imply centered vertically across the scoring rings - not much point otherwise.

That said... I could certainly see the case for someone to say 'well, at least the gun held good waterline elevation' when they have a nice flat string like that shown in the last pic, even if it wasn't perfectly centered on the aiming mark.

Tomatoe, Tomatah. Seems a tad early for cabin fever to have set in (especially for you Erik)... must be everyone just getting all wound up for FCNC ;)

Yes, people sometimes use the term waterline incorrectly to indicate a flat shooting gun. A good shooting gun can hold good waterline, but the group itself is not the "waterline".

Monte, no cabin fever here. I shot the LA State Midrange Championship last weekend and will shoot the Texas Midrange championship this weekend. The weekend after that we have a 1000 yard practice match and then off to Phoenix for the LR Regional followed by the FCNC! That's a lot of shooting in the next month, I just hope my gun hold good waterline! ;)
 
This waterline discussion reminds me of a team match earlier this year where I was scoring for some newer shooters who didn't quite have all of the terminology down yet. They were waiting out a condition change, and the shooter asked the guy coaching; "What's the mirage doing now?" The coach replied: "Oh, it's boiling now - it's boiling over hard from the left!"

LMAO! ;D
