[QUOTE="Derek M., post: 213801, member: 2693"] Absolutely, but sometimes you find that certain chambers work better with a more uniform case, like Lapua and Norma, regardless of whether or not it had to be worked. For the longest time, I refused to pay the extra expense for Lapua brass, as I had plenty of success with Winchester. Then I found 200 Lapua 30.06 cases, new, same lot, for a smoking deal so I bought them. I used half in my 30.06, and the others were dedicated to a 270. While I had acceptable hunting loads in the 270 with WW brass, I found that by reworking the same loads but using Lapua brass, my groups shrank. I also found that I had .0015 clearance between a loaded Lapua and the neck chamber dimension. The cases are 2.49 and 2.50 after sizing and fireforming. Trim length for 270 is 2.53. Top performance and accuracy are based on several factors, but having brass a couple thousandths less than trim length is not at the top of the list, where uniform cases are. That said, Nosler was not making custom brass yet, which I can attest to now, is very very good brass. I'd take Nosler second brass over new WW brass now. [/QUOTE]
