Bag alignment !

[Dusty Stevens]

Lets talk more about the bag fill, I now have the gun tracking pretty good but not great, the stock is the 5/8" and so is the bag, so now do I need to work on taking sand out of the ears? Bag? what am I looking for? Remember this is my first year at this so help me out here. Not sure if I'm going to get to go to Dixon Springs, TN this weekend (have pneumonia that I'm getting over) or go Sunday to BGSL but going to try and shoot somewhere.

Try putting a bit more sand in the ears- make sure youre not on the stitches. Then work on alignment. Twist it and your front rest until it slides straight. If it wont you may need to have your stock milled straight

There is no right answer. You will have to test and see.

I guess I would want to see how the rifle fit in between the ears before I made any comments on whether it needed more or less. I think its also a "by feel" kind of thing.

If the reticle typically goes lower on the target when returned to battery, the rifle is riding higher in the rear, and would typically need a little sand taken out of the ears.

If the rifle is kinda "sloppy" between the ears, I would say it needs a little more.

Again, kinda by feel.

FWIW...My rifles that are typical long range stocks with flat bottoms shoot and track best with a rear bag that allows it to ride on the flat between the ears.

However my rifles that have short range designed stocks (that I shoot at long and short range) shoot best riding on the ears of the rear bag.

A sensitive rifle will give you vertical if it hits a hard spot. The heavier it is the easier you can get away with it

For what all applications is that input based from/toward?
While I have seen the same thing with LV 6PPC's, hunter, and other similar short, lighter weight rifles... have also seen the complete opposite effect with heavier LR-BR and F-Class stocks. Much of what I learned in SR-Benchrest went out the window when I switched to the LR disciplines.
Vast indifference in stock designs, barrel lengths, recoil, torque (twist), etc., etc, to generalize bag effects (both front & rear) - IME.

I shoot UBR from 100 yards to 300 meters, my gun weighs 17 lbs, the bottom of the tracker stock is flat with a slight taper. I have a match coming up this weekend so won't mess with it before next week when I go to lick my wounds ;-) but will try some of both (ears and body of bag).

It’s funny but except for changing my rear bag. Everything I ever learned about short range has applied to Shooting Long Range.

Just shows there’s more then one way to get to the correct answer.

Its hard to see from that angle what I am talking about, but I certainly dont like these gaps that are highlighted.

Get a lenzi top from pma. It uses a regular bag.

Those side bags do look to be upside down?

I think you're right. I dont have one of those rests, but I have seen and used them. And I think you're on to something.

 

[Keith Faller]

I have a newer seb max and the side bags are a teardrop shape. Good friend of mine has a older max with side bags more of a rectangular shape and they tend to roll in on top of the stock edges causing the stock to rock. It can cause big problems. Good catch mike!!

 

[mikeeg02]

I didnt like the gap but didnt look to see the upside down part. I would definitely change that before your next match.

Also the other side of that, is most places will dq you if you cant lift the rifle straight up and not disturb the rest. Also called "entrapment". Some places dont check. But if you start shooting good I guarantee you they will start to nit pick.

Thanks! I'll definitely look at that and change it if that is the case!!

You ought to send that bolt to dwight scott for his special treatment when you have a chance. Youll see the difference right away on a score target.

 

[Shooter13]

Alright, take a look at this (different gun of course) but turned the side bags right side up?! My other gun is already loaded in the truck for a shoot tomorrow or Sunday.
