My brother has just picked up a handful of alco 6.5 bullet offerings the 140, 147 and 160 weights. His BC numbers look incredible but I'm not sure I'm buying them. The 147 interests me the most and looking at running them in my 260AI and 6.5-06AI. Has Bryan Litz done any testing on these or anyone else out there have experience with them? Basically what I want to know if they offer an advantage over the Berger 140s. If not I'm more than happy to keep running the Bergers.
