Re: Choice of long range test loads based on overall group size or vertical group siz

I ran a pressure ladder test, but was getting odd results from compressed loads, and was seeing that from 40.0gr...I don't think I could fit 45.0gr in a 6.5x47 case and be able to seat a bullet...

Try a drop tube.

And seat bullets out as far as possible so they just touch the lands when chambered/
