Sup yall, been a while.
So I use Javilin and TSD .25's, I'm not 100 percent sure of which is going thru the gun when I test but, sometimes my shots are DEAD ON, then every like, 3-5 rounds it ends up like four feet right/left at only er so 100 feet, also the up and down changes to go up or down every third shot ish, but not as severe. (HOWEVER it does concern me becuase the hop-up in my G36 is not having a large effect when I turn it even all the way on.) I know it could be a problem with my G36c (as painstaking a task it is to fix it... I swear I spent like ten gruesome hours on it total over the last two weeks), I have a firefly bucking and an OLD DBC 6.01 in there, it's just not shooting right, do im here wondering:

How consistant are Javy and TSD bb's? Bcuz sometimes my gun is shooting just right, then other times it sucks. Is there an affordable more CONSISTANT bb out there? I hear good and bad about GG's how bout' them Elites? Idk...

Should I also look into washing the bb's? I could but, I think BB's should not fly out like that even if they're not washed really...

Also, if the barrel is old, could it have an effect on consistancy? I don't see how it could, but I need any advice right now lol. And of course, if it could be something else, tell me! (Is it possible my bucking is too loose? Hop-up system too loose? Etc...)
