I see the new Nosler manual does that now as well.
As did the early Nos. manuals.
Quite a difference in max. charges, then to now.
May not be politically correct to say this, but the early versions max's were quite close to where I ceased to add powder in my rifles. Comfortable max..
Still using those older manuals .308/30-06/.303/6.5x55/.375hh/etc. to their max.(or close to) charges to this day.
The first Barnes manual ... that one was over the top. Way over in all of my guns. Never even got close to those recommended loads.
Latest Horn., Speer and some others, they seem very conservative to me.
At the end of the day, one learns by carefull observation over time to read pressure in one's own gun, and to load for it accordingly. Thats why we always start low and work up in small increments.
I measure case web expansion just above the extractor groove, before and after. Any measurable expansion, back off.( a 1/2 thou. is well up into proof load territory with quality lapua brass. Some softer stuff like Horn. will expand that much with factory loads). Any case stretch over a couple thou. in previously fireformed brass ... back off. Flattened/cratered/shallow divot primers ... back off. Less than 10 reloads before loosened primer pockets ... back off. More resistance to bolt handle lift ... back off. Unusually high vels. on the chrono ... back off.
Over the years, have often found best accuracy a couple grains or so (4-5%) under that particular guns first sign of max..
Primer pockets will stay tight, and brass will last a long long time if occasionally annealed.
Forgive the OT OP, wanted to put it out there.
