Finally got to shoot some hand loads in my new sendero. I had bought a box of the hsm loads and my rifle really likes those shot a three shot group of .807in at two hundred yards not bad for factory. I pulled one a part to try and see if I could tell what powder it was (looks like a blend of two powders). I did figure out they are using 49.5 grains of mystery powder. My best group was with imr 4831 by the time I got to shooting the imr the snow was coming down pretty good and was getting cold. I'm excited to see what i can get this load to do. Right now it's close to the max load but with no signs of pressure I'm tempted to keep bumping it up. I'm seated about .010 off the lands.
