Thanks, Carbineman. Strange that they'd leave bad bullet weight info out there for so long.
I received a notice from Midway that these are now in stock, but I decided not to buy any for now. I only have one slug-only hunt a year, so it will be a while before I need any more slugs. I also found out that Winchester is coming out with a new line of sabot slugs, and I thought I'd wait to find out the details on those. Remington may also come out with a 3" magnum -- just guessing.
The only slugs I've tried are the Hastings 15/16 oz lead sabots and the Federal Barnes Expanders. The Hastings slugs were fairly accurate on paper, but I went with the Federals for field use. Both deer I shot with them were DRT.
