Thanks for the alert, Darto! I have ordered some Remington #10s (5-8 days before they arrive at the store). Ironically, I just ordered a set of Track of the Wolf nipples optimized for the CCI #11, which only seems to be available in the magnum variety. I got the TotW cones because I thought CCIs would be easier to come by.
Oh: By the way, when ordering from Basspro/Cabela's, the picture that comes up for the Remingtons is one of a box of 209s, but you can select the #10s from thumbnails below the larger pic. Also, there's a dropdown on the right which allows selection. I was alarmed after receiving my order confirmation email, which showed the 209s, though the description was correct. I called and had a Customer Service person verify the SKU#.
