Nosler has and still does make good bullets but Nosler bullets are getting too expensive and sometimes hard to find in stock. i am switching to Hammer bullets their always in stock and price is not that bad . if you are just shooting smaller meat deer any good bullet works fine , but myself i load better bullets and wait for a chance on a decent buck my meat hunting days is over i let the family shoot the smaller deer.
Those same cup n core bullets work on mature bucks just the same as on smaller "meat" deer.
Even a mature buck is only about 250# max. Hardly a large hard to kill critter.
I still have about 200, maybe more of the 140 Ballistic Tips for the 7-08 and have quite a few 90s for the 6mm.
No more than I shoot of the Nosler bullets in these guns I will keep buying some along the way.
