I didn't weigh what I put in it but it was under 1 gram, but well over 1/2 a gram.
It is suggested by the ones in the know to weigh each cart. School of knocks for sure. There is variance in cart weights and you are talking 0.1 gram type difference
You use it to know when to reload and not harm the cart. Its a great tip from the experts.
I think the cart grabs the first 0.2g to charge (my memory may be flawed here, but that's what I think I read on a post from OF). So it could be you used .2g lread and you are getting to the 0.2g threshold to add more. I think the suggested spread is load 0.6g, prime, use, reload at 0.2g back to 0.6, repeat. Again not my data, what I have read and its from memory. Hopefully the numbers will be seconded
Ataxian, glad you explained the pain reliever comment. Thought you did something odd with that Jaguar which I didn't want to know.
