Re: Muzzle loading integral suppressor

Depending on your choice of projectile wouldn't you still get a bit of lead fouling with smokeless?

Re: New Research Paper shows Crime Decrease in Chicago due to CCW

It's the jobs that reduced the crime.

Unemployment is at a historic low ... hugely important.

Re: Optimists, HPA and National Reciprocity Bills refiled for 2019

The only national 'reciprocity' I would support is constitutional carry.

Giving the fed's more power to limit the constitution on a broader scale doesn't solve the problem.

But, if this would create endless springs of liberal tears I'd think about doing it for funsies.

Re: Marco Rubio introduces Fed Red-Flag law Bill

Police don't need a red flag law to take your gun if you show signs of violence in public while armed. This bill is built on the omnibus crime control and safe streets act of 1968 and theoretically calls for a court ruling based on a petition from family, a household member or law enforcement to tak...

Re: CGS Group Kraken 9

Don't think I left that out.

Re: CGS Group Kraken 9

A factor regarding acoustical behaviours which seems not to be taken inter account in this debate is that of wave reinforcement, or constructive interference - the flip side of which is destructive interference.

Re: Cops in the Parkland shooting

Protect and Serve has been the motto of LAPD for quite some time but I don't know if it is actually in their charter.

I believe the idea that every branch of LE everywhere in the U.S. is chartered with "protect and serve" is a bit of a myth.

That Osprey must be a hella good can outdoors then, at ~120dB it would be quieter than most 22lr cans.
