RE: Need some advice on 243 bullet
There's some GOOD advice above.
In 6mm the Nosler Partition is the best bullet of all the ones mentioned above. I agree, less than perfect shots require a tougher bullet, and in smaller cals, it's hard to beat NP's!!
Experience has shown me over and over that in my 243 Win, and 240 Wby., 100 NP's are the bullet to use on big game!!
