HookieHunter,
Not to step on any toes here but I would look heavily into your form, bench and rest then more time at the range running different loads. I shoot the same gun and I have several loads that will shoot sub 1" groups at 100 yards. Only mod to my gun is the trigger.
I should also mention that weighing your pwder charges is often overlooked when someone is looking to print groups. 1.5 inch groups are not bad groups! Barrel harmonics are a big player when it comes to printing groups. Consistency is the name of the game here. Small differences in powder volumes change the pressures and harmonics in a gun more than I believe most would like to believe. For this very reason I don't shoot pellets. Just my 2 cents.
I did a spring swap on my trigger, it's now at about 3.5 lbs. It does help. In the coming months I will be having a full trigger job done, honing the sears etc. When done I'm looking for 2 pounds of pull and smooth as silk.
Here is my most accurate load, this includes swabbing between shots.

Every gun has it's own personality! It takes more time with some to find the right load. Occasionally there will be a lemon but even those will usually shoot well enough for hunting once you find a load it likes.
Put your money into different sabots, powders, and bullets vs gun mods, minus the trigger. Then range time will allow the gun to tell you what it likes.
Good luck!
