Re: Which press Dillion or Redding
My brother loads both his .45ACP, .308, and his 1,000 yard F-Class 284 Winchester Improved ammo on his 550B. His runout is minimal, and the precision ammo is just that.
He did mention that for his .308 and .284 Winchester:
He decaps with a universal decapper so that the primer pockets get clean.
sizing is done as a progressive;
He seats with the press like a single stage.
