Arrow Diameter an Brass inserts

[davis131]

In my short time as a crossbow owner,I've come to really like 80gr brass inserts up front but seem to be having a hard time trying to find different sizes..I bought a couple doz. .300 that seem just a tad lose for the Diablos an are way loose on 2219s.My question I guess would be what size am I looking for and does someone make them???
