If you are going to reload, you might just as well go with the 280 AI or the 7x64 Brenneke. The Brenneke predates the .270 win by a few years and the .280 by 40 years. The cartridge is one of the most popular in Europe. Apparently, many european nations don't/didn't allow civilian ownership of military cartridges or firearms based on them.Wilhelm Brenneke took the outstanding 7x57 mauser and lengthened the case to 64mm, thus the 7x64. It is a keeper, there are a few Rugers on Gunsamerica etc (but are overpriced). Sako and other still manufacture rifles for that cartridge.

Good luck, CE
