Blocking barrel ports

[rcmodel]

Remember that pressure in the bore increases exponentially

There ya go, using those big words again!

Dang Nab It!

You can use a barrel clamps and a soda can cut to fit over the ports.

It will not fix your problem!

RC addressed it, pitch and fit are the issues. The ports should in theory keep the barrel down, physics are working against you, the gun does not fit you and nothing you do to the barrel will solve it.

Remember that pressure in the bore increases exponentially

By what factor?

But there is something coming out of those shotgun ports, doing something, or they wouldn't waste money drilling them in $10,000 Perazzi Trap guns.

Except that neither Perazzi, Kreighoff, Kolar, Blaser, Zoli, H&H, Beretta or ANY of the major gun makers except Browning do that.

If it REALLY made a difference, why doesn't Browning do it on their field models which are lighter guns typically shooting heavier loads? (Because it is purely marketing hype)

It's the little number in the upper right hand corner

Warm me first if you are going to do that.

Graph for 5.56. I figure that 12 gauge would be even steeper.

 

[oneounceload]

Actually, more likely even flatter as the 12 usually maxes out about 10500-11500

 

[Sam Cade]

Fast powder and a large bore size are going to make the pressure curve steep.

5.56 over time as a direct comparator.




But anyway, lest we get involved in endless digression, porting on a shotgun can't do much if it is at the muzzle.

Now, it would probably work pretty well if you had your barrel ported maybe 6 inches past the chamber. The downside would be that it would blow your hat off every time you pulled the trigger.

I have never fired a gun that defies the laws of motion like you describe.

Thats pretty much it.

I own the BBL he's trying to bubba into some sort of NFA law defying towel wrapped club.

It works like RC described.

You are getting smacked because your cheekweld on the stock is poor.

Those ten ports are not lever camming the shotgun into your face.

You are either holding it quite wrong, welding it quite wrong, or quite possibly both.


In order for the ports to force the gun bbl down fast enough, and hard enough, to force the stock into slapping you, your front hand would literally have to be a hinge.... kinda like a seesaw. And your trigger hand would have to be doing absolutely nothing. And you'd have to have no........ no..... what do they call that ?

Physics

Yes, you'd need to throw all those out the window.

Ok, I guess we have played this tune for all it is worth.
