The change in POI could just be that the screws are tighter or something. I doubt you gained any velocity from drilling the bushing.
Thanks for all the help, I got it out, drill it on the drill press and back together. After doing this and a good cleaning I had to lower the cross hairs about 1″ to hit bull’s eye as before the operation, do you think this is due to increased velocity after cleaning? The gun was a little dirty and my barrel can only be oriented one way so?
First of all, if yours is a new purchase, view the CD that comes with the rifle. Barrel removal is very well covered.
If this is not a new purchase or, for some reason, the CD is not viewable, follow these steps. First, turn the power wheel to zero (0). Then use a 1/8 allen wrench to remove the fore end. Use a 3/32 allen wrench to remove the set screw that hold the end cap and remove the end cap (it may be tight; there is an O-ring that holds it in place) Use a 3/32 allen wrench to remove the four (4) allen set screws that hold the barrel. (Note that there are two different lengths of screws. Remember which length goes where. They are not interchangeable.) Tip the rifle on its nose and the barrel will slide right out.
The bushings are held to the barrel by another allen set screw. It is (you guessed it) 3/32 allen wrench. They are TIGHT! Loosen/remove the front bushing and slide it off the front of the barrel.
When reinstalling the bushing, make sure the holes in the side of the bushing line up with the dimple and screw markson the barrel. The dimple in the middle and the marks on either side of it. You didn’t say what length of barrel you have so: if a 12″ barrel, you will need something, a piece of PVC or a shotgun cleaning rod with a 12 gauge mop, to push the barrel all the way home. Try to line up the two screw hole before you push the barrel into the frame. If the holes don’t line up, use a very special tool, a straightened paper clip, to twist the barrel until the holes line up properly. Reinstall all the screws, loosely at first until they are all installed, then tighten. Reinstall the end cap again alining the hole before you push it in. Remember, the O-ring on the end cap takes a little pressure to seat it. Reinstall the fore end and you’re done.
Have fun, shoot safe and may you never get the flinchies.

It may have been put together slightly off from the factory, or maybe you tightened it in a different order than they did. You want to sneak up on all four screws a little at a time. Don’t tighten one fully and then go for the others. Two of the screws push up, and two push over. You are essentially forcing the barrel/bushings into the upper right corner at a 45 degree angle (as viewed from the stock end). I believe these set screws actually bottom on the barrel steel through a clearance hole in the aluminum bushing.
Is it possible you flipped a bushing over and reinstalled it? That might make enough difference for a small change in POI.
Check those screws in a couple days. If they’re loose, you didn’t tighten them enough. I learned this through experience…
Good Luck and have fun with that SS!
