“aa_limited”what is the main reasn why u want to go with .177 16 g and  is there any reason why you choose 880 fps to run them at.
​are you thinkning 880 fps is the most accurate speed to push them at?


Don’t make generalizations. Just because the optimal speed in one rifle does NOT mean it will be the optimal speed in another rifle. There are many factors, and as I tried to point out to you before, the barrels ordered by the manufactures are unique to the manufactures specs. A LW poly barrel on a Thoams is NOT the same barrel as you would get on a RAW BM500. It’s not just the barrel either, everything that makes a rifle accurate will have an effect. Finding the optimal speed and pellet for YOUR rifle will take time and work. While you may get a good idea where to start looking for your optimal settings by comparing to the same model rifle as you have or one that has the “same” barrel doesn’t them that they will be the same.
