sight radius and elevation adjustment question

[vt35mag]

My POI is 2-3in low compared to my POA at 40yds and I am out of room to adjust the rear sight up and the front sight is fixed.  If I were to move the rear sight back toward the receiver, increasing the distance between the front and rear sights, will that help gain some additional elevation adjustment in the rear sight?
Using the Truglo pro series magnum gobble dot sights.

When I was figuring where to place a mid bead to get the correct POI I moved it temporary towards the breech and then towards the muzzle. If I remember correctly moving the mid bead (rear sight) towards the muzzle raised POI.

If your front sight is a blade you could file it down lower to raise POI

Two inches low at 40 yards?  I would forget it and hunt .  You can see two inches in your hand on paper while you can't see two inches from a distance of forty yards.  Hunt.

That's what most would do, but my OCD won't allow it haha. 
Being that it is consistently low I would like to raise it to keep more pellets out of the breast meat.

Aim for the ball of his head instead of his waddles.

It may be worth the time, money and effort to get a rib mount red dot. Then you can put the center of your pattern anywhere you'd like,  with both eyes open.

I put a vortex venom on my 410 and really like it, so that maybe an option with this one. For the past 10yrs I have ran hevi 13 with this gun and am almost out of them, and have a bunch of tss shells, so I will be switching to that. TSS shoots a touch lower than the hevi 13, so I am wanting to bring my sights up a bit. I know the benefits to having a longer sight radius, but haven't found any solid info as it it pertains to poa/poi with the difference in distance between the front and rear sights.

I'm no mathematician, but as I think about the question, its seems to me that moving the rear sight rearward would decrease the correction to POI that you are trying to achieve. It seems that as you move that rear sight forward you would increase the angle between POA and POI, increasing the correction you are trying to make on POA. Moving it rearward should do the opposite.

I started shooting TSS exclusively in 2009, the year I turned 48, and it became readily apparent that between my aging eyes and the supertight patterns TSS produces, I needed to go to a red dot sight. Will never turkey hunt without one again.

If you're running a rear sight on a shotgun and run out of elevation adjustment on the rear sight and are shooting low, most times it can be corrected with the height of the front sight. I assume you're running the front sight that came with that gobble dot set. If so, try removing that sight and go back to your factory bead. I run the Tru Glo Tru Bead ghost ring rear sight on one gun and the front sight that came with that set was stupidly high (don't see how it would've worked on any gun). So I just put a normal bead on it and was good to go.
