It is the Dickinson, with 30" barrels. Funny thing is, I shot doves with it for two seasons before I put up my grease plate and began patterning my guns. I had no trouble taking a limit of doves with it, with pretty fair averages each time ........ well over 50%, but could recall a few shots each time that I couldn't figure out why I missed. Now I know why. There's just not much meat on the "skinny side" of each barrel's pattern.
I really like the gun, disappointed as I am with the regulation. Before anybody kicks Turkish guns too hard, let me point out that my $489 Yildiz S x S .410 is regulated as perfectly as any gun I have ever patterned. And, when you consider that Beretta has an 8" allowance for mis-regulation, there's not much chance of getting this done by Dickinson I wouldn't think. I wish I could get back to the old thread that ChuckH created detailing how much he moved his patterns by honing the muzzle. As I recall, it was significant.
