Used to use a drop tube. Now I use an electric toothbrush; it works better.CM Shooter, are you using a drop tube or vibrator or what brass are you using when loading 48gr of rl-26? I just loaded up some virgin ADG brass with 140 Nosler RDF and rl-26 and I am compressed at 46.3 and heavily compressed at 46.8. I did not use a drop tube or any sort of vibrator to settle the kernels, which I've heard can help, even so, that is a big difference. I'm also loaded at 2.215 BTO, .040 of the lands in my gun.
