I must have had a typo, as the tightwad is a .570,not .575. I put one in a 12 gauge browning bps nwtf that I had bought last year slightly used and never shot yet.I then tried 3" longbeard 5's last weekend and It was as good a pattern as I have ever seen from a longbeard shell and I have shot my 12 ga bps with a .675 kicks and lb 3.5" 5"s since they came out. 40 yards, I am buying another one for my other bps to mess with after season.
These tightwads are better than any other primos choke I have or do own and honestly better than most,if not all of the over priced "names" on most other chokes. For myself, It would have to be the best "turkey deal" going for equipment.
And do not get me wrong,there are a lot of excellent chokes,companies with a higher price tag that are worth the price.Lots of choices today,It is like a kid in a candy store.
