I was also sad to see that on SBR’s website that several excellent flavors of .458 SOCOM (using Barnes solid copper projos) are now restricted to LE/MIL only, listed with ‘ban by ATF’. Not surprising, but ridiculous. They haven’t banned solids in bolt/double rifle calibers…but that wouldn’t surprise me either.
Any standard .458SC load is a practical threat to various types of armor, as is a majority of popular centerfire rifle ammo. I recall a similar restriction was issued against Barnes .22cal solids (marketed to varminters as low-damage rounds when going for pelts), ostensibly due to it’s adaptation as a pill for the 5.7x28mm cartridge.
Sorry for the diversion but I thought it was worth noting in an SBR thread.
