As a hand loader of shotgun and rifle , i cannot see any reason why steel would be louder in report as both start at super sonic flight . It very well might be someone is shooting Hunting charges of steel 36 grams up with more powder ( which will not be legal in comp or on many clay grounds ) and your rating magnum loads against 28 gram and under clay loads perhaps ?It is also in my experience has a very much louder report, which could become a significant problem for clay grounds.
Steel clay loads are very much different .
Lets be fair If i came on with 63 gram super magnum lead 3 1/2" and the guy next to me was on 24-28 gram steel ? My lead loads would be significantly more in report !
