Thread: 22 cal smoothbore vs rifled 22lr bore RE SHOT SHELLS

The above is all correct. Especially Barry.

I would look at having the end of the barrel portedas Roarless says then fitting an over/underbarrel tube, maybe fill it with steel mesh or wool if you really need to knock down noise. You could shorten it about as much as you like to legal limits obviously, without losing velocity.
Sparrow shot should be stepping out at subsonic velocities so I'm not sure why you think it's hotter?

Hi 11mms
Sparrow shot as you put it is still a lot louder when shot via an ASE Rimfire suppressor
compared to a round of CCI Standard ammo shot through the same gun and supp..
But reading online Fed. rat shot was louder than the CCI rat shot so maybe i could try some of those ..
Thanks for all the input

I am absolutely guessing but I uspect there that the shot is not providing much back-pressure for the can to catch, so the gasses come through relatively unimpeded, whereas baffles will catch gas off the turbulance at the heel of a normal .22 projectile.
also suspect that gas volume would be about the same between brands, for the same load and velocity
I have seen a few posts on this forum about supressing shotguns so maybe reach out and those peopel have some advice.
