Learning to shoot for groups. I always throw last round for some reasons. Pic of 3 groups 5 rounds each, back to back. Center is cold bore with s&b 6.5 140 gr ammo. Other 2 groups are Hornady 140 gr ammo. Disregard 30 cal holes on the bottom.
What might be a cause for thrown round? Thanks.

Something about the fifth shot causes you to place your finger in the wrong spot. Too little finger is pushing you left!

Factory ammo isn't always as consistent as one's hand loads can be.

Shooter is always a factor as well.

Keep practicing. Your likely just getting psyched up once you see how good those first four are. Are you breaking NPA, between your shots?

If you shoot at a target which does NOT show you the size of the group you are working on, you will not get psyched out by the target.
Increase your distance and reduce your magnification so that you can't tell where your shots landed until you walk out to the target.

All that matters for making small groups is accurate rifle/ammo and aiming at exactly the same place every time.

Try a diamond shaped aiming points (targets) as they are easier to aim at more accurately than round aiming points.

Randall, can you elaborate on this?

Ease of cross hairs lined up to split the diamond-shaped target vs trying to place the dot in the center of the target.

Ah, makes sense....thanks.

Make sure your target isn't canted.

Ok, here is my graphic:



Each of the two left shapes are centered under the crosshairs.
Each of the two right shapes are offset to the left by the same amount.

Look at the top of the diamond as well as the circle, where the red shape disappears behind the crosshairs.



Note how much easier you can see how far the crosshairs are off of the diamond vs. the circle because of the angled lines of the diamond vs. the long single arc of the circle.

The most accurate aiming point is actually a 4 point star because you get MORE angle where the aiming points disappear behind the crosshair.

I use something very similar for load development at 100.

Attached is a pdf so one can print their own if they are interested.

I'll toss up a image (non-pdf) so you can see what it looks like before clicking on the attachment.

It has 12 targets on an 8.5x11 paper. In this case, I just used it to test my PCP with 10 rounds prone and put black dots on for the next that I was planning on shooting unsupported. The bigger black dots help with my brain deal with wobble when unsupported.


But honestly, I don't think the issues are with bisecting the target.. I bet it is a combination of fundamentals leaving town.

I couldn’t use a small sheet. Every charge it walks a bit. Sometimes I’ll see it walk almost 2-3 inches from the previous.

Are you guys slightly adjusting the scope between shots in anticipation for where it might lend

No need to adjust a scope at all, especially in between shots.

Either your scope is zeroed or it isn't.

Now you are getting into benchrest stuff. They use an aiming square and you line up the crosshairs with the edge of the square. That way you don't shoot up your aiming spot.
