Would someone direct me to the list of rules, and description of HP silhouette? I have shot SB silhouette.

Aside from the obvious differences, i.e. distance, caliber etc., what are the specific differences between the two?

Thanks.

Here's the link to the NRA rulebooks online. Just click on Silhouette Rifle and there's everything you need to know.

Specific differences other than the obvious: targets, distance and caliber? Practically none. Weight of Hunter rifle goes from 8 1/2 to 9 pounds. That's about it.
