[QUOTE="Darryle, post: 2969585, member: 109917"] Cliff notes version: I have listened to a couple of different podcasts where it was mentioned that if you have velocity in the 2700fps to 2950fps window that it will generally be a very accurate load, it will be more consistent, it will extend barrel life, brass life, be easier overall to tune and work over a wider range of temperatures. The host/guests also more or less dismissed the OCW/Ladder tests because they waste components, shorten barrel life and waste time. Their advice was pick a couple powders based on the velocity you need for the chosen bullet to perform as designed at the maximum distance you need it, choose the rifle barrel length and twist to put you in that window and it would be easy to tune. One example was RL 26 vs N565/N570, one of the powders would give you the consistency and accuracy/performance you wanted. It was also mentioned that everyone should own the QL program, because the data is constantly being refined and will get you in that window quicker. It was also noted that not every cartridge fell into those parameters, because there were over bore cartridges that were at their best when leaned on hard. Looking at several boutique ammunition manufacturers, there are a number of very consistently accurate cartridges that you can not fit inside that window, on both ends of the bullet diameter spectrum. Examples, 22 Creedmoor, 6mm Creedmoor and 280 Ackley Curious as to your thoughts? Can you choose a cartridge for a given bullet design and performance based on the velocity window and it work consistently with minimal effort? [/QUOTE]
