Bert the Turtle, that looks to be a nice buff that you took with your 404. Have you posted a hunt report and photos yet? What bullet did you use?
I've got the 1-8 on my 375 and the 1-6 EE on my 404. The 1-8 has a finer reticle that I think suits the 375's role as a versatile rifle. The 1-6's reticle is more coarse and I think it is better for a dedicated dangerous game rifle, although it did not handicap me at all in making shots out to about 140 yards. The EE version with about 1 inch more eye relief than standard is not currently being made but is still available new old stock and to me it is worth looking for if going on a heavy caliber gun.
