I'm sorry to say that I don't have data on the pellets you mention;however, I do have chrony results using Beeman FTS pellets. They weigh in at 11.2 grains and are extremely accurate in my gun. I have spoken to several other owners who also purchased .20cal guns and pretty much everyone was using the FTS pellets. Well enough of the chit-chat, I have chronied mine on several different occasions and it averaged 907fps. The FTS pellets fit the bore well, snugg but not excessively tight.
