Thread: 303 weight comparison

I am getting the understanding that 165 is a pretty sweet weight for the 308 especially if the barrel is on the longer side.
So.... if we consider the humble 303, it is a teeny bit bigger, so does that mean weights in the 170ish mark are the same thing? Do they make a good hunting projectile in the 165-170gr range for the 303?
Otherwise its 150s or 180s with the 170s all FM's or target jobbies?
