Since I didn’t see it... weight wise
Steel shot = 7.5 grams per cc
Lead = 11 grams per cc
So when you see HW 13.. that’s 13 grams per cc (heavier than lead)
HW 15 = 15 grams per cc -
HW 18... wow.
HW 15 shot size 6 will penetrate gel like BB Steel shot at 65-73 yards !! (But you have a bunch more pellets)
for Duck as Mule Deer said a 12 gauge 3” 1 shot to 3 shot inside of 40 yards - you need nothing more...
The 2 best steel loads - Federal premium, or REmington nitro steel ..
Don’t fall for the blind side / black cloud BS - they decided if they didn’t trim the edges off the square stock that was cut and molded via a die into a round shot they could save money and sell it as extre deadly ... but after it flys a way it does screwy stuff, so the longer pattern suck.
* another thing - get Carlson extended waterfoul chokes for your gun if it has choke tubes, your patterns will improve wildly.
The trade off of course is cost. The best deal going on HW15 shot is at Rogers sporting goods if you buy a case you get a box 12 gauge 3.5” (5 each) for 12.99.. Just the shot alone costs that much.
