Pulse movement


Dustyman

Recommended Posts

I might be asking a silly question here but I have always been aware of a slight movement relative to my pulse when shooting prone. I've always try to compensate and have tried to ensure I timed my shots according to my pulse and breathing and I have always assumed it is due to the fact that the rifle is shouldered over a main vessel but is it a possibility that I am holding the rifle too tightly , when shooting prone, I always try to load the bipod slightly but wonder whether I may be holding the rifle too tight, as other things start to fail with age I will prefer to limit any effects my body has on the shot , especially as blood pressure seems to rise with age and a less physical lifestyle . Should I be reducing the loading of the bipod or timing my release of shot better ? Alternatively should I just accept I'm becoming an old fart and be satisfied with wider groups with age , ?

Why not just load the bipod differently,or hold less tight,or whatever and see if it makes any difference?

I shoot with 4 different bipods,including joy pod,two different heavy front rests,one a coaxial,a tripod and a bulls bag.

Sometimes totally free recoil-not touching rifle apart from pinching trigger.It does not seem to make much difference-mid .2s/.3s with rifles that have never shot any better.Possibly I aged early,of course.

It may be that you are the victim of false memories of previous glories,but I don't think wider waist need go with wider groups-there seem to be some pretty good senior shooters at top Bench Rest events.....Flags...what flags?

Don't lie flat with legs akimbo.

Try lying with strong side leg cocked. This will raise your chest off the ground and will help control your breathing as well as reduce pulse effects.

Try turning the scope down too if using high magnification.

One thing we notice when shooting sitting in HighPower or CSR is a severe pulse, which is due to your femoral arteries getting restricted.

The way round this is to loosen off your belt and try and be relaxed as possible

Thanks for comments , never thought about lying flat having such an effect infact I've always tried to make sure I was flat to the floor to be more stable but can see sense in it . Things to try this weekend me thinks . Much more ponderering to be done now . Mmmm.i can see the logic n the scope mag as I do far better in gallery rifle with open sights than scoped as im less inclined to keep compensating and moving the gun about ,just sit it nice and steady on target and relax .never thought to migrate it to my prone . Good points

Cheers

I can recall the first time I ever witnessed free recoil at diggle. Far braver men than me! A lot of bench rest groups are shot by this method for good reason.

My own limited experience would be to say relax and be consistent.

 

Good advice-good technique is fine,but you have to be comfortable too-physically and mentally.

 

Re Free recoil-yes,but it helps to see it done,and then experience the relative non event yourself.Of course the bags etc do the work.It's not really a field useable technique! The bags/rest also show any heart beat/pulse movement is pretty small-1/8 moa,and only shows up on a 36x scope-its always there of course,but out of sight,is out of mind on this one. I suspect that generally some struggle with the precision of high x scopes,imperfectly supported,just because they magnify wobbles-which remain of course,unseeen ,with more modest scopes.It's that mental thing....

"I can see precisely where I'm aiming,with a 1/8 moa reticule movement" versus "I am unaware that my reticule could really be anywhere +/- an inch on the target".

Choose accordingly,and shoot with it!

Speak for yourself but if I get to pick u up at halfn four and you ain't got your kegs on , I ain't giving how a lift . Gammy knee or not !

Glad I've put new tyre on !

 

See ya in the morn , lock and load ;-)

I am assured shooting between beats is the way to go, apparently the trick is to get your breathing under control, calm everything down, be aware of your own heart beat and take the shot in-between....

This probably should have been posted on the "kit used to shoot tight groups" post but,,,,,,,,10mg amiodipine,,,Lisinopril 5mg,,,,,200mg Metoprolol,,,,,,seems to keep my pulse movement to ,,NIL,,,,,BP 135/70,,,,HBPM,,,60 ish ,,,,,I can shoot between beats too Davy,,,defo the way to go,,,,,O

Hi,

 

I've had the same problem but a little coaching worked well for me.

 

The trick was consistency, hold the rifle but don't grip it too hard just relax into it. The more pressure you apply to hold the rifle the more inconsistent you will be as you'll need to replicate the pressure each time in order to maintain POI.

 

When prone I keep my legs flat and heels touching the grond but about 2' apart. Shoulder the rifle and rest my cheek on the stock, this easy movement should maintain the cheek weld.

 

Slight pressure from my feet pushes my body Into the rifle.

 

I always shoot at the bottom of the out breath as it's supposed to be when the body is most relaxed and you avoid pulse jump. Before I squeeze the trigger I take a slightly deeper in breath and then exhale slowly. The few seconds at the bottom of the out breath is the best time to fire.

 

Using this technique has improved my accuracy and more importantly my consistency.

 

I shoot out to 600 yards on the range with a good group.

 

I hope it helps?

 

Happy to share.
