I'm contemplating building a .458 SOCOM on a bolt action rifle, which I would handload both sub and supersonic loads for.
The HAM'R seems to be more of a reinforced case with a thicker web and small rifle primer, than an improved chambering.
Would it work to size HAM'R brass in a SOCOM die to shoot it in a SOCOM chamber, (in a bolt action remember) to gain the added speed the round offers with the 300 and 265 grain bullets?
You can use SOCOM dies to reload HAM'R cases, jus backing it out enough to get the correct headspacing.
The .458 HAM'R seems to be the same case with the shoulder moved forward ever so slightly, presumably more to prevent it from chambering in SOCOM chambers than for performance, but I can't find the case dimensions for the HAM'R so I don't know what the difference are.
Supposedly, you can't tell the difference by looking at them.
With those extra 200fps the 300 and 265 grain bullets the HAM'R brass brings the SOCOM into another territory, 2400fps might become possible with the 265 or 250 grain bullets.
