Yes, that in 2&3/4" length at avg Vo of 1250fps is one of the best loads available for HD.I like #1 buck in 12 gauge.
Win Super-X patterns well for me.
For personal defense and law enforcement applications, the International Wound Ballistics Association advocates number 1 buckshot as being superior to all other buckshot sizes.
Number 1 buck is the smallest diameter shot that reliably and consistently penetrates more than 12 inches of standard ordnance gelatin when fired at typical shotgun engagement distances.
A standard 2 ¾-inch 12 gauge shotshell contains 16 pellets of #1 buck. The total combined cross sectional area of the 16 pellets is 1.13 square inches. Compared to the total combined cross sectional area of the nine pellets in a standard #00 (double-aught) buck shotshell (0.77 square inches), the # 1 buck shotshell has the capacity to produce over 30 percent more potentially effective wound trauma. In all shotshell loads, number 1 buckshot produces more potentially effective wound trauma than either #00 or #000 buck. In addition, number 1 buck is less likely to over-penetrate and exit an attacker's body.
The only consensus I see is that over penetration is an issue with slugs.
Current commercial #1B pellets usually run close to .286"/33 grains. If .30" pellets are wanted you will have to handload.I like #1 buck as well. 16x .30 cal wound channels that will penetrate plenty deep to the vital organs, not as much penetration as 00. I also like Hornady low recoil TAP 00, don't think they make it anymore.
#4 to 00, no smaller, you need to stop the threat more than worry about over penetration.
I have WIN. PDX1 in my HD 12 ga. It has a smaller slug with 3 00 Buck on top of it. Last round is a #4 Steel shot, because that's what I had handy.
Specifically, yea, that's what I was referencing. Lots of YouTube's out there of shot and slugs vs walls and meat. Sheetrock doesn't appear to be much of an obstacle for slugs. I assume windows are going to be even more of a concern.But it probably goes through walls and still retains a lot more energy than buckshot.
