Advanced Marksmanship Pumpkin head on the stock

[bowshot]

Obviously hoping to generate some curiosity with the Subject Title...

1) I'm prone, off a bipod, bunny ear bag in the back. I'm shooting scoped AR (.204 .223, and Grendel), sometime a bolt (6.5x55), both wearing Scopes. The AR is PRS stocked, the Swede is plain sporter.

I understand that I should be straight behind the rifle. However, when I truely am, I run into these issues:

1) I have to tip my head a tad (maybe 15 degrees toward the stock) to achieve the scope sight picture.

2) I don't understand how the heck to get my head to fully rest on the cheek piece. Ie., when I AM straight behind the rifle, I cannot let my neck totally relax or my head shall slide off the side of the stock, and come to rest on my chin (or my nose... ) in the dirt.

Am I nuts in thinking that if the rifle is in the pocket, which is what 4" from the side of my face, that I cannot have my body and the rifle coaxial and still have my eye behind the scope, and that I can't rest my head on the stock because they are not coplanar? I must be because I keep reading that everyone else is capable of doing that?

Yes, I am seriously ugly but my facial and body countours are indeed... tolerable, LOL!

A bipod that is too short for the shooter would make this happen.

Try not investing the rifle so far out on the shoulder. Keep it more inboard and your punkin' head doesn't have to move so much.

Another cause may be a poorly fitted system pulling you out of a good position to chase the eye relief. Readjust your scope around a correct position: Get straight on the gun, THEN adjust the eye relief using a toady, lackey, or bootlick to move it back 'n forth for ya. You should be able to get on the gun straight with eyes closed, open them up and BAM - sight picture.

HTH,

Re: Pumpkin head on the stock

Understood. Looking at old notes, it seems to me that I had the bipod elevated a few inches more in time past...

did a lot of obsessing in setting the eye relief, but I think you are on it... once I adjust 'pod height I reckon I may need to adjust

Hopefully going to "the lab" tomorrow!

Dang.. got called into work.

If I can get out in time I might make it to the field after the wind settles for the evening.

You may want to initially chuck the bipod and rear bag and attempt building a muscularly relaxed position with bone alone.
Learn this first and then making proper adjustment with bipod will be better understood. Right now, even when you are doing it right it may still be so uncomfortable that you question it all. This is because the position is one which is somewhat foreign to your muscles.

"You may want to initially chuck the bipod and rear bag and attempt building a muscularly relaxed position with bone alone."

Understood, thank you I shall attend to this reccommendation.

I was able to get 40 min of trigger time yesterday evening.

Adjusting the bipod 4" taller brought my eye pretty darn close to straight back behind the scope, But I didn't experiment with the head-rest stuff. My recoil is close to perfectly vertical, moving about 8" above the bull @ 300y (shooting the .223)

If I get the time today, (I'm at work again...) I believe that I'll do a little shop time to bring the eye relief in accordance with my (preferred) bipod height, and then work on resting my head on the stock. It'll be interesting to see the effect on recoil.

I'm able to keep 1" groups @ 300y (all rifles mentioned) with handloads with my old method (faint cheek and shoulder contact, very low 'pod)) but I think its time to break out of that. I find that though my groups are good, they wander day-to day and I think its becasue recoil is not "regular" day to day (because of that method).

Re: Pumpkin head on the stock

Adjusted the bipod 3.5" higher (much closer to prone, no-bipod form) and adjusted LOP and scope eye relief.

Much better, keeping 8" consistent recoil.

I'm seeing that lack of regular trigger time is a poor way to keep "tuned".

Thanks for the input, folks.
