rear bag movement

[dat]

I'm having an issue with keeping the rear bag from moving right when firing due to barrel torque. 6bra, H4895, carpenter 105, 2900 to 2920, rodzilla t rex frt rest, LRB stock, 16.6#~ rifle. Edgewood rear bag, 3" tall, 6" wide, 10"~ long, 12#s~. Plywood top bench. I have tried drywall sandpaper under rest, still kicks. Put a 13# lead slab (with drywall sand paper) next to rest base - helped but still moves some. Looking for ideas

With an LRB? Are you bags in alignment with front rest? At most torque should knock you out of level. Not out of alignment. Cant even imagine this happening.

Is there a chance your bag is backwards? Bags made to be rock solid oriented one way are rocking horses the other.

ears are in back

 

[Clancy]

Depending on the bag, that could be right or could not. I’m going to assume you have it placed correctly, and if so, I can’t imagine how it moves

Adjust the rudder on LRB .
Look at the bottom ..

rudder in line horizontal, needs a bit of a shim for vertical - couple of inches at 300m

Front bag on t rex pivots for alignment, but I set really close to perpendicular to target. I turn rear bag to get equal ear contact, use felt spacers under ruder - attempt to have ears just contain ruder - no sideways movement - and ride the bottom. Expand on your alignment idea, please.

I have my rudder slick taped . Mine is a dasher but the stock tracks great. To move the bag it has to be grabbing on the ears . Have you tried a used dryer sheet? On really humid days they make a big difference.

"grabbing on the ears" That's a possibility. I'll address that when I get the action back (another barrel) Appreciate the idea, thanks

I have blamed this on barrel torque, 8 twist on one and 8.3 on another. Bag goes to the right. Again, looking for ideas

You might want to quarter up ( 8:00) or even sit directly behind the rifle at 6:00. I know it makes a difference for myself when I return to battery off the X

Mine is 6 dasher , 8 twist @ 30 inch heavy varmint .

I sit directly behind the rifle, free recoil. Without the exta lead slab, my crosshairs end up a foot or two left at 300m. Bag kicks right

28" about .900 at muzzle. Ezell tuner

Torque is a rotational force, in this case about the axis of the barrel. I'm not sure that would move the bag to the right.

I'm assuming you are a right handed shooter. Are you sure you are hitting it with your chest? Sitting directly behind it, it is easy to bump the bag with your chest.

I switched to 8:00 ish and just catch the rifle lightly, it seems to help return to battery closer to the X.
You might also try having someone else shoot the rifle.

yes on rotatioal force. And the rudder has quite an advantage being the farthest away from the bore line. I don't know what else would move the bag right
