Pulse in scope

[TEXFIRE%$&]

I have a new ELR rig built by Charlie Melton. It shoots awesome. The question I have is while shooting from a bench with the NF NX8 on all power settings, I get a pulse jump in the reticle. Ive tried loading the bipod more and less,and have worked on a lighter check weld. Ive narrowed it down to my carotid Artery as the cause.
Has anyone experienced this, and is there a fix?
Thanks, safe shooting.

Move the butt of the stock more centerline where it’s not straight shading your collar bone with a vein between.
It’ll also help keep you let head vertical. Feels strange at first but it helps.

Thank you sir I'll give it a try.

Are you using a rear bag? Could try more fill/less squeeze, making sure that the stock isn't making contact with your hand.

 

[spife7980]

Thank you sir I'll give it a try.

I’ve also found it to be from my cheek as well. But the centerline vertical head helps there too. Really it’s just adjusting the stock to fit right. Fidle with it for an hour.

Yes Ive tried multiple rear bags. The one that helps the most is a protector with small ears. I prefer a regular bag and would like to make that work.
Good suggestions. I'll work on that also.
Thanks

Ive been working on being more centered. That seems to put the side of the stock in more contact with my neck. I'll work on finding a sweet spot. thanks

Does it also happen when you’re prone? Have someone take a picture of you while you’re shooting from the bench and post it.

Will do. Thanks

Take 2 aspirin 30 minutes before you go to the range.

I thought about that. Vassal dilator. Might help!

Pentazemin if you want to be OAF

Veins arent pulsatile….

Happens. I get it too sometimes.
different techniques help.
Less coffee, less Cope…. I know, I know.

Had to look up Pentazemin. Fake drugs….

Propanalol is the med oft used. Not advocating for it, just works.

 

[TEXFIRE%$&]

Not into chemical fixes but I agree less BRCC and cope would benefit the cause. My BP is good , checked that but I do get pretty excited when I operate my new freedom seed delivery unit.

I have the same issue with one of my rifles. No matter what I do, I see my pulse in the scope. All of my other stocks and chassis setups have zero issues. I will be trashing that stock when I feel like shooting that rifle again.

I could be wrong but in your photo it looks like the scope to check weld distance is pretty high at least to my eyes. I'd try to raise the adjustable cheek piece a little higher. It might be straining your neck some and causing a problem. Just my 2 cents.

 

[Diver160651]

I don't see the check comb being too low or too high. Can't without looking at the shooter for the most part.

The two main giveaways that a shooter is extremely bladed, is a very low distance between the scope centerline and the comb OR a scope mount way too far towards the rear.

Tall benches, relative to the chairs and the angled benches at many public ranges almost enforce poor posture. Often you'll see a guy bladed and leaning back a bit. When you do you'll see a setup as you do in the image from the OP. Tucking the rile in more in these cases usually makes it worse. For benchrest devices, this doesn't matter as the shooter is not a large part of the system. Feet, hips and shoulders square to the target; hips bent forward at the waist when using a bipod require the chair to be taller, and thus the scope needs to be more forward, similar to how it is set we shoot from obstacles and as a side benefit, a hair closer to when shooting prone.

My 2 cents is work on your body position, then get the gun set up properly, then worry about your pulse way down the list as a lot of your issues will take care of themselves once you're on the gun properly.

Great stuff. Thank you!
you are correct. My scope set up is set far back bc I have been shooting prone with little to no problem with pulses. I’ve had to move to the bench due to the grass being tall at the range where I shoot. I can always shoot from the bench and started having this problem during load development. It is a fixed bench.
thanks for your input. I’m sure that my NPA needs work and will work on tweaking the scope set up. Thanks again very helpful.

Sometimes a simple shorting mat folded up under your butt will help when the chairs to bench ratio is too great.

Update to my post. I worked on the suggestions given here.
Give credit where it is due. Diver160651 was spot on. His suggestions all made sense. I implemented them while dry firing, and all improved the issue of pulses in the scope.
This is what I did for anyone who is having similar issues.
1. Moved scope on the mount further toward the front.
This allowed better set up on rifle.
2. NPA. Squared everything to target. Head, Shoulders, hips, knees, and feet.
3. Centered rifle butt as close to my midline as possible.
This allowed a more vertical alignment of my head.
4. Raised the bench seat to a better/correct height.
This was the big idea that made everything work together.
This allowed a comfortable, relaxed position on the rifle with a correct sight picture.

All points combined to solve the pulse problem. Like was mentioned, correct the NPA issues and the problem fixes itself. That Is exactly right.
Thanks to everyone for their input. Heres to small groups!
Cheers!

Outstanding. I HATE fixed height bench chairs. Even worse, one club I belong to make them out of heavy lumber and they are fixed in the ground. They don't seem to fit anybody and I refuse to shoot from the side of a bench. Not sure whose idea that was but it sure seems persistent in the design of shooting benches.

I bought a drummer's throne (stool to the non-drummers like myself haha). its comfortable and it adjusts up and down. Maybe not for everybody, and yes I need to carry more shit to the bench, but it works brilliantly for me. I shoot from the back of the bench with my body square to the rifle and target. Much better for me, at least.

I got this one but less expensive ones are also available...I tripped on Roc N Soc as some gun sites were selling them as shooting stools and yes, they work very well for that.

Thanks for the info. I have been looking for a portable/adjustable bench stool so I too can carry more shit to the range!
Thank you Sir!
