Thread: Resurgence of interest in the old "Three Oh"?

Greetings Bumblefoot,
Just spotted your post about your Lee Loader. Your .167 powder measure has 98% of the capacity of the 2.8cc powder measure that the Lee chart will give. This should give 37.5 grains of AR2208 (Varget) or 37.6 grains of AR2206H (H4895). 37.5 grains of AR2208 is about the start load for the 174 and 180 grain projectiles and should give around 2,300 fps. For the 150 grain projectile 37.6 grains of AR2206H is a mid load that should give around 2,500 fps. In my .303 I have tried 32 grains of AR2206H with the 174 grain RN that produces a little under 2,100 fps. I am thinking of working up to 34 grains which should give about 2,200 fps. I also tried 34 grains of AR2206H with the 150 grain which gave around 2,050 fps. I am thinking of bumping this load up a couple of grains as well. Both loads shot quite well for an almost 80 year old rifle and a 2.5 power scope and not too far apart either. Happy days loading for your 7.7mm rimmed Creedmoor.
Regards Grandpamac.
