Clear...TNT is actually CCI ammo so let me crrect myself first. Secondly, I have' nt seen a winchester that goes that fast, especially at 40 gr. I found the TNT' s were the fastest and most accurate in my gun and did the MOST damage too. I tested the Remingtons, winchesters, federals (premium' s are my next choice) and other CCI' s as well. I' ll attach a link that shows all the speeds and sizes I used as a basis. As you will see there isn' t a win. that comes close to those numbers you gave me, but maybe they are new. I' d like to try them if it' s true! As for Stingers, thats the only .22 LR I use. I used to like yellow jackets but I' m sure anyone who has shot a stinger after any other .22 LR will tell you they can feel and hear the difference. Stingers are alot cleaner as well. If you shoot a .22 WMR, stingers will seem like a BB gun...and thats no lie! Give me the info on that winchester shell if you can...JDinAB
