I own 2 ticks 7mm rem mag and of lately i have reload and shot MANY other rifles from Tikka's, sako's, A7's, Browning's, Hells Canyon's e few other. From rifles to rifle "we" have MANY different powder charges and performances, 2217(H1000) and 2225(Retumbo) are the go to powders for sure BUT based on my experience you need to start "from the beginning" with your own work, we "all" know our rifles will shoot these loads but how and for how long are different matters. both of my ticks couldn't shoot past 70gr of 2217 without pressure signs be present, Tikka's have the "tradition of short magazine length so as you proceed with greater charges be aware of the "also" increase of chamber pressure, if you loading as "single feed" then keep your safety priority.
2217 is great with lighter projectiles and of course will work with the 162gr as well as we all know, the 2225 is better with the 160+ grains projectiles been slower powder.
"MY" "pet load" has been mentioned in the previous posts here and i really hope you find your sweet spot with easy…
"MY" suggestion is, ADI2217 or Hodgdon H1000 start from 68.5gr, with ADI2225 or Retumbo start on the 71.0 - 71.5gr… Consider your loads as magazine length.
I hope i am of some help, lots more of us here will come with more knowledge than me and info that may be more relevant to you. Check if you have any fellow reloader near you and have a chat.
Cheers.
