Blazer fan here! (Raises hand)
They are great, but, I can't find them in bulk so I have to buy the 50 round boxes. That's the only reason I didn't include them in my above comparison post.
Blazers give me above average accuracy, cleaner burning than most and very good report consistency. No pffft! bang! pop! with them.
They also do great work on tree rats when the round nose is sanded or filed flat. They make a very nice satisfying THWACK! on impact.
