Choke Constrictions

[Stan Hillis]

Also keep in mind that patterns can, and will, be affected by the shell/loading used in it. With the same constrictions, varying the load can vary the percentages of the patterns considerably.

I do understand what Karl is trying to determine. Here's Hallowell's ideas on it. By giving a range for each, Hallowell is allowing for variances in choke profile and loadings used. Very smart, IMO.

I agree with Bob's figures, which are very close to Hallowell's figures. The gun you are considering is a classic improved cylinder and modified..
