Re: Vertical dispertion problem
not being humorous..........when powder charges are not consistent...or a slow barrel....one gets vertical stringing.....

Re: Vertical dispertion problem
Could be an ID10T error too. This is sometimes the result of poor cheek weld or rifle driving, though with the windage being as tight as it is, Bolt's advice would be my first place to check too.

Re: Vertical dispertion problem
I guess ID10t= idiot, thats probably the main problem here. The windage seems to always be like this, but the verticle doesn't get below 2". I have a chrono on the way maybe th sd is accounting for some of this. Rthur

Re: Vertical dispertion problem
I guess the fact that you are using Fed GMM is lost on a few here.
Either you updated your post or I just realized you are shooting a gas gun.
Try single loading rather than from the mag. This will force you into individual shot setups rather than trying to make one setup work across multiple shots.
This will also make the rifle recoil the same, not differently on the last shot with holding open on an empty mag.

Re: Vertical dispertion problem
9h I usually load 6 and leave the last one in the mag after 5 shot group. Next time at the range I'll give it a try. Rthur

Re: Vertical dispertion problem
Rthur,
It is not uncommon to have vertical dispersion due to poor bag handling, scope issues or inconsistency in torque for your action screws. I seem to run into the problem more frequently with a bipod than bags. Considering that you are using FGMM you shouldn't run into bullet seating depth issues either. Good luck.

Re: Vertical dispertion problem
I'm also wondering if my inconsistant cheek weld plus poor parallax setting could contribute?

Re: Vertical dispertion problem
Vertical Stringing is a component of Breathing issues, Cheekweld issues, or shouldering the rifle in anticipation of recoil. The question is, did they string down in a straight line or, a mixture of up and down ?
Parallax is usually responsible for so called "fliers" and rarely go in a straight line, however, a scope being incorrectly set for the shooter can cause shadow either at 12 or 6 'O clock which will cause a vertical component
Rifle wise a poor barrel will help this, a barrel too thin that heats up can also cause stringing usually in a poorly made rifle.

Re: Vertical dispertion problem
Thanks for the help gentlemen, I think I'll go back to lesson 1 and work my way through trying to improve my basics.

Dave, you just suggested that he anneal loaded ammo as he is shooting FGMM

Re: Vertical dispertion problem
That would definitely (permanently) solve the vertical stringing issue (LOL).
