They do but they only added it for their new BE-86 powder. There is no 45 ACP +P data for other Alliant powders on their site.Alliant has data for 45ACP +P IN their 2014 load manual. It can be viewed or downloaded from their website.
But again, not 45 ACP +P data.Go to Western Powders web site. Click on updates. It has all the Ramshot and Accurate powders data.
That is good data, thanks for the link...
