Pellets for Chrony work

"chasdicapua"I need to do some chrony work for my .25 and see that Gamo has some pretty cheap .25 pellets that weigh almost the same as the JSB Kings. Any reason not to use those as they are almost half the price?
What do you want to get from the chrony work?

Maybe you should ask yourself why you use the JSBs rather than the Gamos normally. If it is because the JSBs are better, would using the Gamos give you the analogous results you desire?
