A couple questions: 1) I have a .300 wby, model 700 sendero and want to work up a good load. any information on a good starting point would be appreciated 2) from what I read, I cannot start at the rifleing and back off due to the design of the weatherby chamber. so for this round, any recomendation on a .col ? 3) should I crimp? Any help would be appreciated.
