A really SPECIAL project that you have never seen before.

"Hearing safe".. so you can actually hear the difference? Have you measured it?

Have not measured it but its definitely an improvement. And yes, you can actually hear the difference which is significant.

I was thinking that's a small can for a .22, what do the baffles look like?

Just regular "K" baffles.

Very interesting. Must have something to do with the reduction of the muzzle blast. .38 SPL load we used was quite mild and the powder charge probably burned completely in the barrel.

How many?

He did mention they minimized the barrel/cylinder gap. I'd imagine if your 38 had a larger gap which could account for the difference.

[Pinsnscrews]

The gas volume escaping through the cylinder gap of the .22lr is much smaller than the gas volume escaping from a .38 load. Even if the cylinder gaps were the same, just the bore volume alone is much higher.

Doesn't seem like it. Some does blow by but to minimize that I lengthened the forcing cone a bit to shorten up the gap.

Please explain how opening the forcing cone lowers cylinder gap? Call me cynical on that reply

[HotGuns]

Technically not the forcing cone, but the barrel gap was minimized to reduce the gas escaping. I just made it longer than the factory barrel.
Feel better now?
