If you go look on page 2 of this forum, there is a post I started back in October about the White Hots. Lots of links to articles written about it. At first it sounded like something revolutionary, but lately it looks like they are just 777 without the dark color. They do still have the crud ring however.
I don't think Blackhorn 209 has a thing to be worried about, not from these.
SHOT Show starts on Jan 15th, they were going to wait to introduce them there, but they have been for sale at some Cabelas stores for a week or two now. Real world (non writer) reports indicate they are rebadged white 777 pellets. I will test some when I get to Cabelas. Was planning on going today, but Mother Nature has given us freezing rain/drizzle all day, and it is about a 5 hour round trip. Maybe next weekend?
