It's SCIENCE! MAC's new Slotted Muzzle Brake

What a test subject:jester:
My NERF Three-O-Late:applause:
A 13" sporter barrel, center-grip XP-100.
Some 168 grain VLD's loaded on the warm side.
A larger diameter brake would be more efficient for sure, but that is not what I was looking for with this compact set-up.
Two vids below...

    I picked this XP up used, with the exception of the brake.
    It was a little beat up on the stock and it needed some internal strengthening.
    I also wanted the base holes opened up for a larger thread and a second one added in the back.
    Chuck suggested cerakoting. I said, do what you want.
    Between him and one of the gunsmiths they came up with this.
    Ya think, I might need to be a little more specific next time?:jester:

    So, I understand the pink and gray pistol. It was a joke, I get it. But what pray tell this THIS color scheme all about?

    My boys like the paint scheme, my oldest likes that brake idea, he is recoil sensitive, your gunsmith knows you right brainers are in touch with your colorful sides:).

    Well some of those loaded hot would make for better videos. I will be loading up some more 1000gr 12ga slugs for my 835 and 935. They don't stabilise for crap but they will cut down a 6"dia tree.

    I like the lines of that pistol and stock, Ernie. And the initials on the grip are a nice touch. As to the color scheme, well, you won't be in danger of losing it! :up:
    (I've seen some stranger colors and artwork on heavy 100 yd. benchrest rifles, and some of the rifles at .50 BMG shoots are out of this world; got a lot of area to cover on them, and they do some neat artwork on them.)

    Realistically, I won't be shooting anything heavier than a 168 grain in this set-up.
    155 grain or 168 grain A-Max for deer and antelope.

    Recoil junkies unite!!!! I am working on a muzzleloading wrist rocket as we speak. A 500gr slug ahead of 90grns of powder is wicked. My Kentucky pistol with this load is crazy. A rangemaster at MG asked to try it and the trigger guard broke his middle finger. I think he thought I was performing or something.

    Noooooooot exactly what I was thinking. But, you just proved my point even more.

    The real donor is a CVA inline since my daughter decided she didn't like muzzleloading. I am going to cut it down to 16",recrown, add a mid grip and make a trigger link. They tumble out of the slow rate Kentucky pistol barrel but the inline was designed for modern bullets.

    Why would they not stabilize? I've been casting my own Foster 1 oz. slugs for nearly 30 years with a Lyman mold. The 1 oz. slug is mostly empty space. It would be no trouble at all to cast a 2 oz. slug of the same length by making a new base plug for the mold. The 1 oz. slugs shoot just fine out of my Hastings Paradox rifled 12 ga. barrel, and I see no problem with a heavier slug of the same length.

    Expound on this 2 oz. slug. What is the design?
