We recently tested IMR 8133 and found it a very good fit for overbore cartridges. Link takes you to both the written article and the Ultimate Reloader video:
Yup, it's a compressed load. Also shoots well a couple of grains lighter. Not as good from my rifle, but still quite good.Hey guy, I was playing around with Quickload and see that the case fill is at 114% with 77 grains for the 7 Rem Mag and 150 ELD X. Did you get a powder crunch with a drop tube? I was checking it out for my 7 RM and 300 Win Mag possibly in the future.
