1/4/22 UPDATE - Currently out of the shop sick, not sure if its the Rona or just a bad cold being there are no tests available in Ohio. Anyways, taking few days off to get better then I'll be back to it.
The Rio Series was developed in 2020 specifically to meet the needs of the Crawford Co shooters. An unexpected change in the shotshell wad required new a product to be developed to help keep shooters competitive. The Rio Series has also shown positive results in testing with Federal Top Gun as well.
