I have been working with loads for a 25-06 sendero and am trying to decide on projectiles. It likes the 75 grain VMAX and 85 NBT. These are the only true "varmint" (read: advertised as=explosive) bullets that I would consider. The sendero also happens to like the 100 grain SMK but I am geting pass-thru's with critters getting back down their holes (will be hunting from squirrel to coyote). I am considering the 100 or 115 NBT but am worried that they won't be explosive enough since they are really meant to be for deer. Can those with experience please comment on what has worked in the past. BTW "LR"=~500-600 yds.
