I was browsing through my latest edition of the Handloader magazine, and was looking at the 6.5 RPM. I normally look at speeds and compare them to my 260 Rem. This time I looked at speed but also powder consumption, and thought, "Nah, not worth the gains if I have to use that much more powder. Plus, my 260 will still easily kill deer at 400 yards, and if I need something bigger I will use my 30-06"
Kind of cracked me up at myself, thought I must be getting old. BTW I am only 38
PS. another contributing factor may be that the price of powder is creeping up. I like to check "shots per lb of powder" and using a 90 grain charge sure makes the powder go down faster than 45!
