Reloading .303 British : Lead projectiles ???

 

I have a gas check maker and with .014 alloy make all my own checks for everything under 1900fps but over that velocity have found that the copper checks work best. My alloy is one I mixed to use the different alloys I had with a 47-33-20 (ww-pure lead-lino) and have absolutely zero problems with lerading or any other type of fouling. I lube with a 60/40 bees wax/Vaseline lube 

I have found that Blue Dot is the very best powder out of the many that I have tried in the 303 with 17.3gn pushing the 190gn bullet to 1800fps. Blue dot is not position sensitive and does not need a filler . I have put many cans of blue dot through the 400 LS, 303, 7x57, 6.5G and 20 VT. It is a great powder for everything from the little fireball sized case up to the 404 Jeffery that a friend uses .
