Hey guys, with your advice I've now reloaded for the first time. Thanks! So as our snow melts I'm looking forward to getting out to my favorite shooting area and seeing what I've done. So I have five each of cases loaded with 68 - 70.5 grains of retumbo in half grain increments topped with 160 Sierra game kings. I'm looking for the tightest group so should I clean the bore, fire 2 fouling rounds, shoot my five round group with a couple of minuets between shots, let the bore cool then clean it and go through the process again with the next group and keep repeating that through all 6 groups? I guess I want to know when your working up a load how do you guys go about your testing.
