Wiley, we use mostly I4350 and Re22 in our 7mm Rem.. I have one, my pal has 4 or 5..they usually use 140's for deer and elk, with some 160's....My pick with the 140's were BT's...but I followed the Alliante data, and it offered much higher loads than other data..it would move a 140 at 3400fps..as for lighter loads, my use was 120's either Horn. hp, or Nosler BT...loaded them for coyotes, but my wife shot many antelope with these loads..they were hard on meat if one made a bad shot, but killed like lighting..I also shot a bunch of coyotes and some antelope with Serria 100 grain hollowpoints..but every coyote I hit with them ran..not far, but they all ran a distance...
