Most of the reviews im seeing and my own measurement years ago were in the 31gr to 35gr range (actual weight) for a T7 pellet. Ive seen people claim as high as 37gr. I have not weighed one in many years.
85gr by volume of Triple7 FFFG should be reasonably close to 2 pellets. 85gr by volume of BH209 will be fairly close too but will give a few more fps with a heavier bullet such as a 300gr.
