[QUOTE="rbTanzan, post: 2529522, member: 53978"] Your starting load may be guesstimated from your previous loadings for that rifle. What kind of muzzle energy have your previous loadings been producing? 4400ft-lb, 4600ft-lb, 4800ft-lb? Aim at something a little below. Check out manuals and data like Hodgdon.com and Barnesbullets.com. Clean your barrel well (sometimes copper-bullets are less-forgiving to barrel fluctuations), and start working up, looking for an accuracy node in the 3000-3100fps range. (e.g., a 225gnTTSX at 3000fps produces approximately 4500ft-lb.) For example, if I guesstimated that 99gn-102gn Retumbo or RL33 would land "in the zone", then I would start with a single 97gn and 98gn to be used as foulers and chrono-ed to make sure there are no wildly excessive velocities. From there it is just careful loading, careful shooting, and interpreting results. (Disclaimer: I have used the 225gn TTSX in several 338WMs. It is a good bullet and pretty easy to work up loads with. Use a chronograph.) [/QUOTE]
