Take a 270 bullet a 6.5X55,30/06,6.5/06,280 bullet throw them in a bag,shake them up,and pull one out.Does not matter which one,they will all do the same job.Reading ballistic coefficients out of a Reloading Manual is meaningless as they change with velocity.

Stupidity left unattended will run rampant
Don't argue with stupid people, They will drag you down to their level and then win by experience
