[QUOTE="Petersen, post: 700488, member: 8372"] Read this thread a lot and Broz helped me with quite a few questions. I just received my 7-300win a couple weeks ago and I am in the barrel break in process. The freebore on my reamer is only .180 and this will give me the option of using a uni throater if I need more freebore to shoot the 180 bergers over 3100 or if I need more jump for accuracy. I am shooting the 162 Amax for the break in process and I will probably continue to use them this season for a sheep hunt. The barrel seems a bit slow as of now according to the chronograph. I have not verified the velocities. Here are the numbers. 77.5 H1000 avg is 3071 with sd of 9. 76 retumbo avg 3027 avg with sd of 10. Both loads are 1/2 to 3/4 moa at 100 yds. The specs on the loads are this. The amaxs are .010 off the lands and the new brass shoulder is moving .011 forward after being fired. I am also using federal 215m primers with Norma brass. The rifle was put together by ssg/ Nate dagley. Defiance action with a 27 inch Brux and his mini xtreme break in a manners stock. I will update with pics later on and more info as I get more time invested into in. I only have 15 rounds through it at this time. I know the round may be better suited for the 180 vld with more freebore, but I will most likely stick to the 162 Amax this season. [/QUOTE]
