Thread: 7mm Rem Mag Reloading troubles...

Imo ladder test is ok if seeing what pressure and an idea of velocity and gives you an idea of maximum. Can't see it being much good for finding accuracy although many people use it as a starting point. Way I see it if you pull a shot slightly then it stuffs up the data to much and it's easy to do. If you do a 3 shot group and pull one the other two should give you an idea whether it's worth going back to that charge and trying again. When I had the same problems as you , changing to the bergers and tmk's made a huge difference straight away even with my start loads. Think from memory I was around 73.5gns of 2225 with the 162's and dropped back to around 69.5 when I tried the others. All ended up with a very similar charge weight and velocity once I worked back up. They were all similar with their weight and bearing surface so not a radical change
