My go to lightweight bullet for regular shooting with my SOCOM is the NOE HTC 354 FN. With the PC coating and a GC they come out to 360 grs. and they shoot great and function great out of my RRA SOCOM upper. I was looking for a more pointed bullet for the SOCOM but wanted a flat tip for magazine loading. It has a crimp groove for loading in a 45-70 but it works great in the SOCOM. I also do load it in the 45-70 and it is awesome in that cartridge also.
Below is the bullet coated in HiTek with the GC applied.
I started liking PC better with my rifle bullets so the bullet with PC and a GC a sized. Also the bullet loaded on both the 45-70 and the .458 SOCOM.
