[QUOTE="lancetkenyon, post: 1473808, member: 68875"] Neither RWS or Lapua makes a .280 Rem brass, let alone .280AI. RWS does make a .270 Win brass that could be necked up to .284", trimmed down .015" and fire formed. A viable option if you want to fire form brass like every used to do before it became a standardized cartridge. You could always buy a hydro forming die and get 90% cases. But Lapua only makes .30-06 Springfield brass, which could be necked down to .284", but they will be .031" short at least, and probably shrink even more when fore forming to .040" or so. You might never get that length growth back by the time case life is over. And for those that want properly headstamped brass (I couldn't care less myself), those are both a no-go. Also, RL26 is more temp sensitive than RL23 over about 84°F. Pressure spikes rapidly. That doesn't work for me in AZ. I have not found that with RL23 in my .280AI at all. From 4° to 110°+, shoots within 20fps. [/QUOTE]
