Does anyone have any experience to tell me if there is any point-of-impact change in groups shot with a smokeless muzzle-loader with a brake versus the same rifle's groups shot without the brake?
I've read that suppressors cause a significant P.O.I. change, but haven't read anything about muzzle-brakes. |

I don't know about suppressors but when I take my muzzle brake off the POI changes a little bit. Not a whole lot but some. I haven't shot it extensively without tho.

My sml POI dropped 1" at 200 yards. I put one on my 300 Win Mag and POI did not change near as much if any at all. My Magnetospeed causes a drop of around 2 inches at 200 yards on every gun I have tried it on.

So many variables on this topic. Ignitions....barrels...stocks.....various brands of brakes...recoil pads...and finally shooter. Best way to find out for your gun is to shoot it at 100...200...300...yds and see to make sure

The guns I have shot with and without (SMLs) have shown some POI change, some more than others but all showed some..

This is another topic...........just like cut rifled barrels vs. buttoned rifled barrels? Go to the range and shoot it with and without the brake and you will then know for sure how your rifle reacts! Anything you put on your barrel will act, to a degree, like a barrel tuner? They make such devices and are widely used in rimfire benchrest competition. They actually screw in and out much like a micrometer with similar markings. You tune your ammunition with them..........so, it stands to reason putting a brake on can do the same thing? Probably with fatter stiffer barrels that a lot of our muzzle loaders have, you may not see a significant difference? Probably thinner CR or RF barrels will show more deviation?
If I think of it, I will shoot two groups next week and report how my rifle reacts!

Thanks guys, all good information. Deadeye, that is a very cool idea for a muzzle-brake. And Richard, you certainly make a lot of sense explaining barrel tuning. Years ago I owned two Browning center-fire rifles equipped with Browning's "BOSS" (Ballistic Optimizing System)barrel tuning brake. One of these was chambered in .300 Win Mag and I made the mistake of firing the rifle at a deer........without my usual ear protection I always wore at the range, just wasn't thinking and never wear hearing protection when I'm hunting. The report was so loud that I have never felt to this day that kind of sharp pain in my ears. I really thought that I had severely damaged my hearing. I even felt my ears to see if any blood was coming out of them. I sold both rifles and swore I would never own another rifle with a brake.
Twenty-five years later I still feel I can handle any normal amount of recoil so I ordered my Hankins 45-SPML without a brake. I can shoot it well for quite a few rounds (275 Accumax launched with 78 grains of IMR 4198) without any recoil discomfort and continue to feel that I am not too sensitive to recoil. But I watched the video of the recoil measuring machine someone posted and saw how much recoil is reduced by the brake, almost incredible. Now that I am in my advanced age and not as tough as I used to be, I've been thinking about putting my pride aside and considering to maybe have Jeff install a brake on my rifle. Would make it very comfortable to shoot for an extended range session and I can remove the brake and install a thread protector when I'm hunting so I don't destroy my ears.
So, coming full circle, that is why I was wondering if there will be a P.O.I. change. Maybe the thread protector should be machined to weigh the exact same weight as the brake so the barrel harmonics are as consistent as possible? I seem to recall that the Browning BOSS system had an optional thread protector that essentially was identical to the brake except it had no ports machined.
Thanks again for the good information.
