Title: Has anyone tried Federal's Guard Dog 9mm?
Post by: TpaBayFlyFisher on October 20, 2011, 02:49:21 PM

They are described as 105g low recoil and:

"It features a unique expanding full metal jacket design that can effectively eliminate threats while not over-penetrating drywall and plywood barriers.

Federal�fs Guard Dog ammo works by utilizing an expanding polymer core. The full metal jacket design can�ft fill with debris from a wall or heavy fabrics, yet upon impact the bullet expands to as much as twice the original diameter. Tests conducted by Federal showed that their new design could pass through 4 layers of drywall and then stop in less than 15�� of ballistic gelatin. Traditional hollowpoint ammunition on the other hand passed through 4 layers of drywall and then continued on to completely penetrate 15�� of ballistic gel before exiting the other side."

I think it's the old EFMJ which has been rebranded.  I would have to research further but I think the EFMJ was an underperformer.

Basically if you want your 9mm to perform like a 380 Auto you can load it up with the Federal Gaurd Dog ammo and that's what you're going to get.

The Federal Gaurd Dog ammo is the same design as the EFMJ but different bullet weight.  IIRC the EFMJ was 124gr and GD is 105.  Five grains of that 105 weight is the polymer.
