I have been shooting a Beretta Ultralight since 1996. 1 1/4 ounce of #5 lead (where I could use lead ) has been my favorite load. Good for a honest 40 yards. Where I had to use steel- 1 1/4 of #2 steel but it really is only a 35 yard killer. Anything farther is iffy! Any load heavier than 1 1/4 is punishment!
