This is my first Brocock now I have had a lot of pcps but this one is new to me. I got it in the .30 was wondering where the happy spot for the common pellets weights jsb 44.75gr, jsb 50gr, hades 44.75gr and zan 56gr reg is currently set at 150b. Does the reg need to be broken in and if so how many shots my huben was recommended 300+. Any information on this new to me platform would be greatly appreciated.
