Thanks. I've got the 5th edition. I'll try to borrow that version. All I have right now is longshot, but I feel like that would be too new to match up.The 4th Edition of the Lyman Shotshell Reloading Handbook, has load data for 16 ga. Activ hulls. Data includes 1 oz through 1 1/4 oz.
Depending on what powder you have available, may be able to match up loads,
