A great multi-purpose 209 from the good folks at Federal.
federal 209a primers | Federal 209A Shotshell Primers
For standard 1-1/8 oz loads, the primer energy has a significant impact on the peak pressure of the round. You must carefully follow the instructions in the load manual, whether it is printed or available online. You’ll want the hottest primer you can find when you’re dealing with low-weight loads like 3/4 oz in 12 gauge, because low pressure is your enemy.
Federal 209A’s are the some of the hottest primers available so you must use them accordingly. Since I load 3/4 oz 12 gauge, Fed 209A’s are my favorite primers.
