arcticap - no, Wonder Wads would not be out of the question, nor would the idea of making my own out of felt or some other material. most anything would do, if i needed it. i was just asking about these shotshell wads because i have a bag of 500 and haveno 28 gauge shotgun. my real concern though was the tight fit,and any pressure issues it might cause. however, from the other responses, it sounds like the issue has been resolved by the manufacturers of sabots using better materials.

so, everyone, thanks for the advice. i appreciate it. i have several Knight "high pressure" sabots. from the packaging, it sounds like these are made specifically for use with heavier loads. thanks again.
