Then I'd say you are right on track.
I almost tried some CCI Lg Rifle BR Primers today (good call).
I was looking at your rifle in the pics and trying to use the scope and the "guesstimated" length of pull in order to figure your barrel length.
Is it 22" ?
Also, I noticed that your last two loads went at in increase of 63 fps and 80 fps respectively. I started to hit diminishing returns at my 71 grain to 72 grain step.
What you are showing at 70 grains corresponds well with where I am also.
Lookin good Jery
