So I'm a month late to the party but this has been a great thread to read through. I think it's a testament to this round that is still so popular and I can't blame you for getting into it. I shoot a straight 284, 6.5x47 and 6BRA in f-open, 300wsm, 270wsm (170 EOLs) and 300wm for hunting, and the 6.5x284 was a round i just had to build a rifle for, so I have one in the shop now.
I'm planning to load 4831sc and 142SMKs in Norma brass with Russian primers. I'm hoping to be in that 2950fps range. This will be an all- purpose rifle for me, targets out to 1200 and whitetails out to 700. Build is a Tenacity LA (full nitride), 28" Krieger 8tw HV, McM a5, hawkins 3.715 bottom metal and Accu Mag (300 wm) mag, calvin elite trigger.
Good luck with your new rig, let us know how it develops.
I'm in the process of putting together a 6.5-284 hunting rig built on a 1910 Mexican Mauser. The Mauser action length is perfect for this cartridge.
Thank you Sir and I will keep you posted!!
