Prone question: flyers to the left - weak buttplate contact?

[nester]

Thank you everybody - my question about flyers was answered completely, and also got really helpful ideas about other issues.

So here are my summary (it might be useful for somebody in the future..)

Weak buttplate contact.
Actually it is not the issue by itself, but mostly it should be firm.
1. Just pull the rifle back. Put buttplate closer to the middle of the body - so it is not pushed by the shoulder. Watch that right elbow goes to the same place after each loading, not creeping forward.
2. Move handstop forward
3. Don't push the handstop with the left arm. Left arm only supports the stock like wooden bench rest, not holding, pushing or moving it.

Position slips down during the session:
1. Do some warm-up and stretching exercises before shooting
2. Use sling tensioner to compensate small sagging

Unexpected flyers on multi-bull target:
1. Poor natural point of aim (NPA). Each shot should have same extensive NPA setting procedure

Interesting ... I have very broad shoulders with rather prominent collarbones. I have my bullplate offset a little so I don't feel it hitting my collarbone....this may be incorrect.

I might just have to add pounds to me to cushion the contact on collarbone(not too adviseable or I will begin to wobble on the newly aquired belly), or just go for that tight shoulder contact and live with the contact.

Good post - Thanks.
