yotenewbie:
A good place to start for varmint loads in your 25/06 [yes, I have reloaded for one for 25 years] is Norma MRP powder and the the Hornady and Sierra 75-90 grain varmint bullets.
Work up to 57 grains of MRP and use the Hornady 75 gr. HP and the Sierra 90 gr. HPBT bullets.
MRP can often be difficult to find, but stellar results will be worth the search.
Also, IMR 4350, IMR 4064, IMR 4831, and Reloder 22 are good powders as well for the 100-120 weight bullets, and are not bad at all with the lighter weights.
Standard primers are fine; I have used mainly CCI primers over the years.
Good Luck!
