So, I'm trying to tune my gun and the numbers are everywhere (well, not as close as they should be). Speed is varying about 3.4%, 812 to 840 fps. Average is right where I want it at 828, but want more consistency. Average weight is 34.01 (in this tin)
Then it hit me, I'm shooting straight out of the tin. The pellets are JSB 33.95 in .25 cal.
After weighing 120 pellets, I see a weight range of about 1.4 grains over 120 pellets. That's about 4%
So, the speed variance is 3.4% and the weight variance is about 4%. Seems like a pretty close relationship.
If I get some time to shoot in the next couple days, I'll run an experiment where speeds of lightest and heaviest are compared, try to validate how tight the relationship is.
Has anyone else already don the physical experiment and can validate the relationship? Saving me the time of doing so?
