I've finished a .308 build and I've noticed that the rifle has a slight side to side movement when I'm looking through the scope.  I'm not "heavy handed" when it comes to shooting it.  My bolt gun doesn't do it.

Suggestions?

Are you describing receiver rattle?

Heart rate and breathing

Timing makes that a non issue.

If you have loose components tighten them up otherwise learn to shoot in between breaths.

No, no loose components.  Same bipod and rear bag.  Is there such a thing as a "wrong" bag?

I'll pay more attention when I shoot again

I'll lightly wrap my fingers around the forward side of the grip.  My thumb doesn't touch the gun when I'm looking through the scope.  I have a (two-stage) flat trigger, so only the tip of my finger touches the trigger, and it's a very light grip when I start to pull it.

Out of curiosity, what power is the scope set at when you see this?

My range is only 300m, so the power stays between 12 and 15.  

I checked the receivers for play and I torqued the tension screw in the lower is still holding the upper tight with the lower

I presume the side to side movement is rhythmic and synchronized with your pulse...  yes?

That’s a thing?  As light as I hold my rifles, I’ve never even thought that my pulse would have an effect on them.

Well, yes it's "a thing"... the higher the magnification setting the more likely you are to see it...  12x to 15x is a little on the low side so I would imagine that the movements seem "small" in size...  but you didn't answer my question (there are definitely other possibilities) - pulse synchronization - y/n???...

I honestly have no idea, but I'm gonna pay attention this weekend.

Just a suggestion, but record a video with your phone at your next range session. If it’s filmed directly parallel to the rifle, and at the same approximate height of the rifle so your hands aren’t obscured, some of the posters will be able to evaluate your form/positioning/technique to offer more detailed suggestions.

When doing this, if you notice the “scope shake”, be sure to mention it out loud while recording to allow ppl to really focus on what is occurring just prior and during that phase of the firing sequence.

Good luck

Pulse can absolutely show up in your rifle/scope, yes.

And it did.

I took my precision guns out today and did pay attention to my heartbeat and when the gun moved.  I’m not going to lie, I was quite surprised by that.  Steady and calm breathing was a help.
