Mouse holes in K baffles

[Enfield577]

Sorry if you guys have answered this 100 time already, but why the mouse holes in K baffles, I can understand the 45 deg hole allowing gas access to the void behind the cone shape but why the additional hole in the side of the cone.

This lot is new to me so trying to learn lots

Thanks

I once explained this in terms of a fluid logic example of an pulsing water pic head
with no moving parts. Image the gasses as a mob of 5 a.m. first day discount shoppers
who are about to burst through the doors, overrunning a poor guard and each other.

Sending some into an expansion corridor somewhat relieves the mob pressure but eventually fills up the
that area. Either the frothing at the mouth wide eyed screamers come back whence they came or you open up a small
opening that they can more slowly enter the main stream and also run into the main mob interfering with and disrupting
their stampede.

The students grasped that right away and then easily proceeded to solve the coupled differential equations.

The mouse hole allows the gas pressure that has built up in the coaxial (outer) chamber to be directed back out and across the main gas flow thus causing it to disrupt.

Is the mouse hole only on the front side of the cone ie picture 2

Is this ever referred to as a mouse hole or only as a "Dater Hole"

Mouse hole

Thanks for the replies guys

the small round hole at the flat of the baffle is a dater hole and typically only in the first or blast baffle of a can.

the scoop you are looking at was done with a ball mill (more than likely) but has the same effect as boring at an angle as the original Micky Finn patent. there is a hole diagonally across form the scoop at the apex of the cone and then in older versions there is a mouse hole at the large diameter of the cone. this hole at the larger diameter is placed over where the scoop of the next baffle would be so it dumps gas into the stream and at the area of the scoop causing more turbulence. think of the gas as sorta zig-zagging through the can.

None of the good K baffle cans use the mouse hole so I would skip it. Just put a dater hole in the blast baffle.

specifically they dont use the hole at the larger diameter of the cone/ spacer. tirants and elements true, do not use this feature.

As well as Elite Iron, Gemtech, or Coastal.

i dont take 2 of those seriously and gem-tech has only recently done anything worth while.

the original Finn patent has the hole at the large diameter of the cone but they also have features that no one is using in the newer baffles either. it all seems like a give and take.

[Schulze]

Which two do you not take seriously? Coastal has a K baffle .22 can that meters 5db better than an Element on a 16" barrel.

Gemtech's Multimount 9 is only a few db off the Tirant.

Am I the only one that appreciated the mob reference? Well illustrated.

I was under the impression the Prodigy was for rifles and the Element was for pistols?

The Element is a better high pressure can but you can put it on a rifle. It is actually quieter on a pistol.

The mouse hole in a K baffle allows the gas jet from the angled side wall to enter in front of the conical baffle.The dater hole in the large end of the conical spacer allows that space to fill at low back pressure and may provide turbulence in front of the next baffle and allow drainage.

there is no dater hole in the large end of the cone. the dater hole is only located at the flat part of the baffle and usually at the blast baffle only.

the mouse hole is at the large diameter end of the cone and adjacent the other at the near apex of the cone (which is adjacent the scoop at the entrance at the flat) see my drawings above.
