RE: Rem 700 & Powerbelts
I have been shooting the 295-grain Powerbelt AT's exclusively in my Rem 700 MLS ever since they hit the market. It will print three shots at 100 yards into at least two inches any day of the week, and has shot groups as small as 5/8". I do not use T7 (I didn't like the results I got out of it), but I have been using two, 50-grain Pyrodex pellets without any problems.
