it seems that after only 2000 or so shots my whisper is slowing down most likely my fault,shot 300 10.6gr pellets & a few lite ones in it before you all showed me the diff. . sorry mr. tuna I really ought too learn to read first & then shot! I've gotten alot of ideas from all the threads here,but I'd like some fresh ones or old on the best things too put in a whisper .177cal, I know a grt111 is going in,but I'd like ideas on best springs,seals & any thing extra too make it top notch,I'll polish & true all inners myself(or have the boy do it lol). so please a few thoughts my way if you get a moment. THANKS IN ADVANCE!!! P.S best places to buy too?
