please tell me i dont have to trim,

[Win75]

I may be anal in my approach to loading hunting ammo but I trim every case, whether it is new out of the bag or once fired. I check the cases for every loading after that also.

I have found that many times new brass is in fact in need of trimming.

I just trimmed a box of Norma 6.5x55 brass after firing the factory load. Every case except one was excessively long.
