For 3-4 years I've had success using Autoject with BD .5cc -29 gauge - 1/2 inch syringes. Had a few instances where there's been misfires so I decided to purchase a new Autoject and switch to the SureComfort 1cc syringe. The Autoject instructions do not list SureComfort syringes on the the depth setting chart. Does anyone use this combination? Need to know how to set the depth on the Autoject. Thanks.

I have not used autojet , but found the 1/2 inch needles have bent a few times so do inject properly, I use 7/16 long and had no troubles getting the juice in the right spot. Dave in AZ

Suggest you install an empty syringe and measure length of needle sticking out the end after firing
