Still the best!
Jason Tennant (Minnesota) | January 19th, 2023
Have not had a chance to shoot these yet but as a long time boss shell buyer of multiple gauges I figured I would leave a review from just the unboxing . Shipping - awesome and as always it was crazy fast . Shells - all were in good condition with tight crimps , my only complaint is the new nickel heads on the shells. I prefer the taller brass head . I am fully aware of the function and purpose of the head length going all the way back to paper but still prefer the taller version . She'll pouch - I have a stack of these and the one I received with this last bulk order is not even in contention with the others . Probably not something I would ever use , especially with shells that are not water sealed. Disappointing quality on that . Other than that I am sure these #1 loads will be a train wreck on the snow geese !

Ordered my first 3 boxes of BOSS shotgun shells. Service was great. Now just waiting for Geese and duck season to try them out!

Got 2 cases for hammering Texas Snow Geese and they are absolutely amazing to watch work. 1-5/8 of #1 copper plated bismuth. I don’t think I will shoot anything else at geese from now on. It’s 137 pellets of DRT going out at 1350 fps and I wouldn’t be surprised if they worked amazingly on predators as well..

First run with Boss
Peter (Iowa) | December 26th, 2022
Ordered a couple boxes to give a try on late season Canadas in Iowa. Went out this a.m. -6 degrees, snowy, windy, and crushed my limit. Impressed is an understatement.

Folded at 50 yds
Kerry (WY) | October 22nd, 2022
Shot a mature Canada goose, folded it. Dropped 47 yds from me and had been flying inbound...must have been over 50 when I shot. Shot through a full choke. Bird had 3 pellet hits. Excellent shotshell!

Boss Three Inch # 1's! Oh- my!
William Heliker (Olalla, WA) | July 26th, 2022
Cant wait to spank some geese later this season. I always wanted some # ones for geese especially when the geese are a little bit out there. Thanks Boss. Please make this a yearly event, selling a limited run of #1's!
