Late to the party, but am passing along the following reminder. Shot passage/flow through the forcing cone constriction, as with the choke constriction, is an orderly process, not some slam, bam chaos. The leading shot pellets speed up to get out of the way of the following pellets. Since there is no extra energy input available, the velocity increase must come at the expense of pressure. That is, the pressure drops across the forcing cone constriction and across the choke constriction. I know this is counter-intuitive, but it is so. If not, airplanes don't fly.
Post back if you desire further discussion.

What goes wrong then, Don, when barrels are ruined at the choke by HeviShot? Is the fluid flow principle for lead and steel only? One of my best friends is the owner of two of the major aftermarket choke tube companies, and although he makes his chokes out of very good steel for the purpose, he will not warranty his turkey chokes for use with HeviShot. Occasionally someone will send him a burst barrel and try to blame it on the chokes. He knows when he sees it if it had HeviShot used in it and will call the owner and ask what he was shooting. Usually they own up to using HS. Happens a lot more than you would think. Not a rare occurrence at all, and these are new made guns.
