I have only shot jacketed rifle bullets in my rifles.
I bought this rifle off GB 2 1/2 years ago.
It shot ok, but got worse.
I cleaned the barrel with shooters choice.
Looking thru the tube with light, it always looked clean, decent.
Once someone mentioned leading/ gahling, I used my cheapo e bay endo scope and saw the real ugly reality that you can not see, with ones eyes, at least, my eyes.
Anyway, feeling better about this gun/deer season.
Going to clean it again with the Kroil, JB paste, then shoot the 746/200 rnd nose again to verify.
Thanks to all
