[QUOTE="Muddyboots, post: 1949713, member: 63925"] Interesting discussions but here are a couple data points to ponder going forward. For giggles, I ran my 24" data through Hornady ballistic calculator using G7 0.298 for the Nosler 150 ABLR and the results were a bit interesting. Used [B][U]very basic parameters[/U][/B] at 1,000 ft elevation [B][U]so don't get your shorts in a wad.[/U][/B] I also used 10,000 ft as another calculation since it seems most of my elk hunts are at 10,000 ft and the results were even more interesting. Again don't get your shorts in a wad. These are just basic parameters I use to compare bullets on consistent data points that I prefer. Alliant also shows the data to be within their load specs so this is not a close eyes and hope it holds the load either. At max load, I do not show any kind of pressure whatsoever so I may inch up a bit to see where I start to see it. The load data is for a 150 gr Partition so the 150 ABLR may provide a little more leeway. In fact, I willing to bet in a longer 26" or longer barrel with RL26 to cook some more, it should reach 3150 fps or more. There is more opportunity here than most realize if you build the right rifle. Berger 170 EOL looks really interesting and the new Nosler 165 ABLR also has promise. So let's all agree the .270 Win doesn't have the trajectory of a 45-70😂.
