Just picked up a pretty nice one from Simpson's . It's chambered in 8x58rd and I have gathered most all the supplies I will need to cast and reload for it . I'll be using 45-70 reformed brass and Lee 8mm Maximum bullets . Just a couple of questions . What range are the 2 leaf express sights calibrated for ? Also I have a supply of Unique , 2400 , acc 2200 , varget and 4198 powder . I want to stay around 15 to 1600fps . I'd like opinions on which of these powders would be my best bet generally speaking . Thanks for your help .
