Guess they weren't as scared of lawyers back then.
Oh yeah and Lefty I have a .243 that humms along at a furious 2450 fps and I'm still confident of my penis size!
Ever cast your own rifle bullets?? You'll care a lot less about speed if you do. Trying to get speed with my 375h@h with a 280 cast would be maddening, so I've gone to just below the alloy destruction point where the bullet properly obdurates to fill the bore. It is around 1900 fps and she'll do just over an inch at 100 yards. If I want power I'll go to the 300 tsx at 2550 fps.
My 405 is the maddening one right now-- I'm on the second powder with it with its cast bullets. It puked with 4895, now on to rl7. It is starting to show promise but I haven't had enough time to work that one over while setting up the other four I've gotten this year. Two 270's, a 7stw, and a 35 whelen are taking up just a bit of time lately. I aim for 1 moa to 200 yards with cast bullets using factory blade sights.
Your 7 rem loads are about 5 grains over published cup data from 25 years ago. Hodgdon 26 doesn't go up to 69 grains until you are pitching a 120 with I 4831. Lyman is similar. If you have a loose chamber or warn throat you may be fine, otherwise I'd take a look at strain guages as they may be an awakening.
