Reloading .303 British : Time to Test “New”Loads

I would have thought that 41 grains of Varget under a 180gr bullet would have had a bit more velocity than that.  

 

I don't plan to chrono my loads, unfortunately, too much time to set up.   I plan to follow the Hornady and Sierra loading manuals and keep under the max load.  I've got the latest release of both. I have chrono'ed my 174gr SMK loads with Re15 and that's how I settled on 40.0 gr. 

 

I have found a wide range of listed max loads for some of these powders in the .303; particularly Re 15.   The Hornady and Sierra manuals were fairly close if I remember right on comparable bullets at the same muzzle velocity; and are both less than what Alliant has on their website for that powder as max.  Varget may be another powder with a wide range of published max loads.
