there's nothing wrong with the speer reloading manual= i've used them and pacific all my reloading life( since 1970) - the one i currently have is 1991 issue- first you have to decide on a bullet weight that will get the job done for what you're going to do- i use the 180 b/c i get a lot mule, elk, moose, and the occasional bear- for strictly deer, you can drop back to 150- i do the east slopes of the rockies, on horseback- it's also dependant on the twist of your barrel- it's all in there in the back of the speer manual- i know for a fact that i can't go heavier than 180 as 1) the heavier bullet seats in the powder , and 2- the greenhill formula says i need a twist of 1/13.4 to stabilise a standard 180- when you go to 200 it says 1/10- and that's good enuff for me
