I've been loading and shooting the 260 since it arrived in Remington's model 7.

I have NEVER loaded a 260 case. All my 260 cases are reformed 243win cases. Just lube them up, run them into the die, load them as normal, and shoot them.

Using 308 cases will require turning the case necks and other tedious work. Stick to 243 cases.

I don't drink or Smoke. I spend my money on gunpowder and gasoline.
