In the paper this morning is a chart from Tom Roster showing effective loads and distances for various shotshells.
The story with it is important, for sure, but this is the only chance you'll have at that chart unless you go through one of the CONSEP courses next year (no more scheduled this year).
It's copy righted, which means it cannot be reproduced in way without his written permission...that means photocopying it here, too, by the way. Please don't get yourselves or Ifish in trouble.
It's pretty interesting information for myself and others not as well-versed or immersed in ballistics as many of you are.
There's a clear warning as well to all of us to do everything possible to curb our (collective, not specific to anyone...I, however, am occasionally guilty myself) over-optimistic shooting, especially at public areas where we're easily seen by not only the rest of the public, but by anti-hunters.
Thanks for the ear.
