Re: 6.5 long range cartridges
I am sure the 260 Imp., is a very good cartridge that does come close to the 6.5x284. About 15 years ago I decided to build a cartridge based upon the old 250 Savage case, but in 6.5 caliber. I blew it out like the Ackley cartridges to give me more case capacity.
So, I drew out this new "baby" sent the drawings to Pacific reamer and presto, I had a brand new custom reamer.
Garland Gilbreath of Triple G gunsmithing built this new rocket launcher for me using a Model 7 Rem action.
It is am awesome cartridge, almost an exact duplicate of the 6.5 Creedmore, problem is; I have to make every case. I can buy the Creedmore cases from Hornady, call me lazy, but I am shooting the Creedmore now much more than my own.
Same thing for the 260 Imp., great cartridge, but, easier to just buy 6.5x284 cases I think. Same results.
