Alrighty then, Sir Jerry. Below are the ones that are getting tried with 83.0 grains of AA-2460 in Daisy the .458 Ruger No. 1 with 24" factory barrel. The COLs and BOLs may be considered +/- 0.005" when they are shown as rounded to the nearest 1/100th inch. All the brass cases used were selected for exactly 2.500" length, for recipe specifications. The SAAMI .458 Winchester Magnum has a chamber length of 2.520", so I am happy to make trim-to-length 2.500", and maximum case length for .458 WM+ handloads is 2.505":
That last one is the safest one for any Lottites trying to shoot .458 WM+ ammo in a SAAMI .458 Lott chamber, because they will not even be able to chamber the round. The other four rounds might possibly fit into the chamber of a SAAMI .458 Lott, so the caution still applies:
