I've used one of these inserts for a total of 300rds. I had the straw mod before and it ran well. I would have 10-20 out of 100 over thrown.
That has been virtually eliminated with the brass insert. I don't know why this works but it works very well. I started to time my loads and even noticed a few second decrease in time to throw. It seems to run faster from start to 41, and I have not modded my Chargemaster.
Again I don't know why this works or why the straw mod works but this was a very nice addition for the price of lunch.
Btw I have no affiliation or benefit in the sales of these inserts.
Great product
