What advantage is there to a ported muzzlebrake vs. a solid one? I noticed that my ss 1000 has one. I got it out today to see if my trigger finger has gotten any stronger.

"Theoretically", although reality seems to have fallen short in respect to proving it, a ported brake would help enhance the accuracy of the gun by allowing the gases that would come out just at the base of the pellet once it is clear of the barrel/muzzle to be re-directed away from the pellet base, thus not contributed to any turbulence that might put it off course.

As mentioned, there doesn't really seem to be alot of "hard evidence" to support this idea, it's more of a "sounds good, so it's probably true" concept.

Take a look in "Accessory Topics" at the Muzzlebrake vs. Silencer post, it talks about this sort of thing a bit.

Interesting, Phil's idea there. If you look at it- he calls his design an "air stripper"- not a "brake" and some of them sit further back on the muzzle (i.e. behind the crown/tip) than a typical brake found in the market.

His price point also seems to add some credence to the idea it may be a properly engineered device- i.e. £45.00 (roughly $90 USD) vs. a typical "generic" muzzle brake of about $20-40 USD. Heck, in the UK a silencer can be had for less than $50. The note about "it is CRITICAL to get the distance right" also adds fodder to the idea of generic off-the-shelf brakes being unlikely accuracy enhancers.

Maybe someone can clarify his terminology as well: "I could get groups of 1" at 45 Yds this is a HFT gun shooting at 7 mag." What is "7 mag"?

Apparently his design works (or so he claims)- but I haven't seen too many other brakes out there with that level of engineering and "non generic" build.

So- maybe the "theory" is correct- but the "application" with off-the-shelf stuff from companies like Beeman and the backyard airgunsmith-for-profit types just hasn't been done properly.

Glad you asked about the 7 mag. I thought if I asked it would be a "newbie" stupid question. It seems like the stripper might act like a venturi the way it is configured. Like the pellet sucks air in counteracting the muzzle blast?????

It's almost as though the cone is just a separated extension of the barrel- once the projectile exits the barrel proper, there is that wide open space for expanding gas/air to release- but the projectile continues on through the "secondary" barrel in effect with a wide-open rear to it.

Makes me wonder how delicate the balance is on it. For example, is the 'cone' slightly larger than would be the rifle's barrel? And, if the cone or its mount/housing gets mis-aligned, even just a little bit- how much will it affect the projectile travel- i.e. a moderate misalignment could interfere with the pellet path and literally "bounce" off it.
