[QUOTE="Lobber, post: 2330132, member: 95131"] Thanks for the reply Shane. I guess I'm a little confused on the twist. It seems that min twist recommendations are most often established using sea level as the elevation input. Is that not the case with Hammer? I'm confident those bullets absolutely need the recommended twist, or faster at sea level, but higher elevation should allow for stabilization with a bit slower twist.. Unless they are using a higher elevation for their calculations... I would be quite surprised if that .5" twist difference made that big of a difference above 5,000' but I could be wrong. For example, Barnes recommends a 1:8 for the 7mm 168 LRX, but my 7RM has a 1:8.5 and shoots lights out with them, but again I've only shot it above 5000.' I'm excited to give them a try, but like anything I suppose it could lead to disappointment. I'll definitely use a method for load development that you describe. It's interesting to me that there isn't really any published data for 6.5-284 with RL26, at least that I've been able to find. It does seem though, that I can basically do the same thing I did with the 142 ABLR load development where I started at 49gr RL26, shot up to 55.5gr where pressure signs arose, and landed at 54.5.
