I am going to do a couple of posts on chrono threads- Just called Ronnie Sunshines in Berko as I had an enquiry on a pellet to possibly use to chrono, post TX clean (and relube - when I relube it).. contrary to everything I think I have heard, which is to test both high and low but that low weight gives the highest chrono reading- ie test as LOW as you can, in case lightweight lead readings could find you over 12- Ronnie Sunshines Berko, when I called to clarify a pellet weight, he advised "You should test on the heaviest pellets"
Now, that seems to me - a 180 on most other opinions I have heard- ive seen posts, which am sure had lower weight pellet recommendation for .22 chrono tests. I was thinking of using lighter Hobby .22 11gr?
Anyone clarify for me please, while test both, its the lightest weights that are going to give you highest rating. Sunshine must have though I was using PCP. He did not ask what I was using- just NO- use heaviest you can get.
