NO MATTER WHAT LOAD YOU END UP USING GO WITH THE RHINO CHOKE FOR YOUR 870. IT WILL OUT PERFRORM ANYTHING ON THE MARKET. THE NITRO LOADS ARE THE BEST! THE HEAVY SHOT LOADS ARE GREATAT DISTANCES 30 YARDS AND GREATER. BUT THE WINCHESTER SUPREME LOADS ARE JUST AS GOOD AS HEAVY SHOT AT 30 YARDS AND IN. ALSO, I WOULD NOT SPEND THE MONEY DIFFERECE BETWEEN A WINCHESTER SUPREME SHELL AND A REMINGTON HEAVY SHOT SHELL. BALLISTIC EXPERTS AT RHIMO AND NITRO SAID YOU WOULD BE WASTING YOUR MONEY!
