So I ordered some of the Winchester 124 grain 9mm bullets. My question is, what's the best way to find load data for these? In the past I've always used Hornady, Speer, etc or one of the companies who produce a reloading manual so I could just follow the manual. Since Winchester doesn't have a manual what's the best load data to use? Also for OAL is it safe to just seat these to the same OAL as the factory Winchester White Box ammo?
