With California requiring all big game hunting next year to be done with all-copper bullets, does anyone have information on whether there are any reloading differences/nuances that need to be adhered to? I have never reloaded 100% copper bullets and still have a cache of lead jacketed .308 Hornady and Sierra slugs for my .308 and .30-06. I've read that copper bullets of the same weight are necessarily longer and that the ogive bearing surface can spike pressures from a normal handload. Where's a good book/place to bone up on these non-lead projectiles? Thanks.
