Of course they got more speed. 3 Firestar pellets weigh 12gr more than 2 standard Triple7 pellets. Both are claimed to be the 100gr equivalent. Obviously you are going to have more speed with more powder until barrel length limitations kick in. Simple math 100gr charge of 2x pellets weighs an average of 60.75gr and a 100gr charge of 3 FireStar weighs 72.95gr.
