[QUOTE="Broz, post: 379272, member: 7503"] Nate, I am not pushing this thing for velocity either. minute or no flattening to the primers. I have had so many 300 wins shoot so good with 77 gr of H-1000 that I only tested loads of 75, 77 and 78 gr. The 77 gr load was so accurate and shows no sign of vertical stringing even past 1000. So why fight it. I should add that this reamer has some free bore in it. I measure the "O" give of the rifle at 3.065" with a 180 Berger. My most accurate load that I am using is seated with an "O"give of 2.950" so I am .115" off the lands. This fits in a STD magnum mag box. I played with this testing at 300 yards and the results were minimal but it did seem to like the jump. The next step is to move this load into some RWS brass. Now here is the kicker.... I already had a 300 win being built when I found this rifle laying lonely at a gun shop. 1/2 way through the work up on the 7mm/300 I agreed to sell it to a friend that has never shot much long range. He is a guide for Elk and needs a good rifle. Yesterday he was doing all the shooting and is amazed with the accuracy and inlove with his new rifle..:) I am to pick up my 300 win today. I am a huge fan of a 300 win but this 7mm/300 has my attention. One day I may have to build another. Jeff gun) gun) [/QUOTE]
