Re: .243 Bullets for Mule Deer
Have had excellent results from the 95 gr Nosler Ballistic Tip - it's the single most accurate bullet my son and I have tried from his 6mm Remington, and is a lot tougher than many would think. Typically get an exit with it, even shattered the bone of the off-side leg after passing through the chest on one deer at nearly 300 yards. It has become our favorite 6mm bullet.
That said - I don't recall ever using a "bad" bullet from the little 6mm Rem.
