Yes, with my Polytech. Been trying to nail down the problem. Tightening up the bedding has helped some but I'm still not getting the kind of groups I think I should.

I'm almost 100% sure it's the gun, not me. I get nice small, round groups with my M1 (and everything else).

poor trigger pull.

looks kinda like the butt of the stock is slipping off the shoulder.  It would be a tight group had it not steadily moved.  reason I say butt of the stock slipping is b/c it looks to consistent in movement in one direction than to be jerking the trigger.  then again, just a guess.

Sling too tight.

Dragging wood.

NPOA.

I would say this shooter is losing NPOA.

Looks like he/she is likely shooting prone and the elbow associated the the trigger finger is slipping further to the right during recoil, thus mis-directing the muzzle to the left.

I was constantly fighting this whilst wearing "tacti-cool" elbow pads firing prone.  These pads are just too darned slick to keep NPOA.

But, they definitley keep the blisters at bay. :)

If I might be stupid for a moment, what is "dragging wood"? Never heard the term before. Is that a gun problem or a shooter problem? Thanks.

Copied from Grin's post -We Don't Need No Stinkin Sandbags:

Master Sergeant James R. Owens instructs shooters that the position of the right hand must be such that the trigger finger is able to move without touching the rifle stock. The finger touching or brushing on the stock during trigger pull is called, "dragging wood." This makes it impossible to pull the trigger straight back or in a fashion that does not disturb the sights. According to Master Sergeant Owens, a symptom of this is a group of shots strung out horizontally.

The United States Army Sniper Training Manual agrees with Master Sergeant Owens, and further states that touching any part of the rifle - including the trigger guard - even at a slight angle will disturb the sights.

It's not stupid, it's and attempt to learn.  Thanks for asking, now you (and anyone else who doesn't know and reads this) will know.

Dragging wood is when an improper grip of the firing hand on the wrist of the stock results in your trigger finger touching/rubbing the side of the stock as your trigger finger puts an increasing amount of pressure on the trigger.  This can result in your trigger finger (since it is moving and touching the stock) disrupting your sight alignment on the target.

Only the first "pad" of your trigger finger (about the middle of the first pad actually) should be used to press the trigger rearward.  This will help you keep the rest of your finger off the stock.  I've seen folks really struggle with this on AR's when they slide their firing hand too far up the pistol grip (to where it stops from contacting the lower receiver).  Some folks also have problems with those big old aftermarkt synthetic stocks for the 10/22's.

Thanks guys! Cleared that right up. I was kinda hoping it was a gun problem, like the op-rod rubbing the inside of the stock or something.  ;)

Speaking of pulling the trigger of an AR (not to hijack the thread or anything), I discovered long, long ago that, due to its extremely short "reach," the best way to pull an AR's trigger is not with the finger tip or pad, or even with the distal joint, but with the proximal joint (of all things!). I've taught this trick to a number of AR shooters over the years and every single one of them has reported back to me that their shooting with AR improved doing this. Before y'all have fits, let me hasten to add that I don't shoot any other kind of gun this way--just ARs.

 I have 4 Ar's----2 with standard triggers that I don't use the pad on my trigger finger.
The triggers heavy and I feel better with using the first joint.
The other 2 have double stage triggers with lighter 2nd stages. I have to use the finger pad on these so I can control them better. I find if I use the first joint, I let off some shots before their time.

from the Guide
Title: Re: Shot Group Analysis #4
Post by: voortrekker on December 03, 2007, 09:54:00 PM
Hmmmm.......and the Guide strikes again.

It looks like I'm gonna have to bring out the old grey papered "rifleman's bible" once more(like the twentieth time).

Especially for you, M1A4ME.  With all these darned questions!!!!!!!!!

What are you trying to do, make us all riflemen or what???????

I'm liken it though, keep the questions coming.


I bring the "Rifleman's Guide" to the range with me always and learn something new EVERYTIME, and when I thought I knew it all, I don't.


The Guide is totally PACKED with useful information and it takes time to absorb it all, many rereads, at least for me.

You know something?  Another reason for finding some buddies to shoot with is being able to learn from each other while at the range and while discussing the results of the range trip together.

I've found (in my job as an process engineer) that the best way to learn from an incident (good or bad) is to get together with other knowledgeable people and discuss what happened and why it happened.  As a group you'll come up with more good ideas and gain better understanding than you will on your own.

Guaranteed.

In the military we just find someone of lower rank to blame things on.  THen we deny knowledge of their actions.  But your way may work too.   ;D

Now that I think about it, I can prolly imagine.  ;)

But if you just must share, feel free to PM me. I'm always up for a poor taste comment. Especially one about wood.  ;D

Yeah we do.

Sometimes we even blame it on higher ranking folks (we actually get away with that one in the Guard). It's ALWAYS the Platoon Sergeant's fault.
