Does anyone know where I can buy shooter than 5” barrels that are 26-27grams?

I’m assuming the “shooter” is a typo and you meant “shorter “. I also assume the 5” is a typo since all darts (at least the thousands I’ve seen) are shorter than 5”. Maybe you’re including the shaft in your measurement?

How long are the shafts for these darts?

I got my set some time ago and since then the plastic shafts broke and I replaced them with metal shafts. Not sure how long the originals were but they were shorter than my current ones, which are 50.3 mm, including threads.
