I've owned and shot Encore platform rifles since they hit the market. Great rifles and easy to modify the frame for better accuracy and shooter preference.

Now this is my opinion only, you can take it or leave it......

Unless the PB is the only bullet you can find, I'd suggest changing, especially for longer range hunting/shooting and bullet performance. Yeah, there will be guys come about, saying there's nothing wrong with a PB and long range shooting. Myself, I simply ignore it.

If you want to get the MOST from your Encore platform rifle, I would suggest getting away from pellets and start shooting loose propellant. Your rifle will shoot Blackhorn 209 without any modifications that other rifles may need (breech plugs).

Prior to BH209 becoming available, I shot T7 through my Encores. Since BH became available, its the only propellant I've shot through them and would never switch back. I am very partial to Barnes bullets, which is what each Encore platform rifle I've owned shot, VERY WELL and at longer ranges (200yds).

My "go to" load in all my Encore platform rifles was:
110grs volume ...... BH209
Barnes 250gr TMZ bullets
CCI 209M primers

From all my Encore rifles with the above load and bullet, I zeroed the rifle for 150yds, which put me slightly over 2" high at 100yds and 6.5" low at 200yds. Bullets were seated HARD over the propellant.

Although this worked in all my rifles, I would never imply that with your current load, you'd even come close to matching it, which is why I made a suggested change. Without actually shooting your specific rifle and specific load, and at the ranges you intend to shoot/hunt, you should never just count on ballistic charts.
