[QUOTE="BountyHunter, post: 92937, member: 12"] The most accurate rifles on "this planet" are BR rifles both SR and LR unquestionably. No one uses AA2520. So no reason to even consider it as a possible powder for either, so not sure where how you define the most accurate rifles. However, when considering a possible powder a simple ladder with chrono will show you that barrel's nodes with that barrel, bullet, case primer combo. The ladder will show you the grouping node and the chrono will show you the MV node which normally are the same, not always but normally. Easy to pick a powder charge in the middle of the node and then tune seating depth and neck tension. That methodoligy has been proven time and time again by the some of the best guys shooting the most accurate guns and then some just use the trial and error method, but most still use a chrono for the LR guns. MV, ES and SD are not as important for the SR guys. As far as your IMR4895, you must be talking for NRA highpower and NRA LR, where the accuracy standards required are much less than LR BR. Have not seen IMR4895 on any equip list for LR BR matches. Bottom line if your accuracy standard can be reached without a chrono, good for you. However, if someone is wanting to reach the top levels of extreme accuracy, then a chrono has been proven to be a very useful tool for most people who compete in that area. Kind of hard to imagine spending $2000-4000 on custom guns and not spending $200 for a good chrono to set it up, but to each his own. BH [/QUOTE]
