I usually hunt with Remington corelockts in my 270, but my dad picked me up some ammo from Bass Pro, and it is Winchester AccuBond 140 Gr. Bonded. They have the silver shell, and the bullets themselves are black with a red tip. They look like ballistic tips to me, but I don't know. What's the difference between these and corelockts, and do y'all recommend that I use these?
