300 gr powder coated in 458 SOCOM

[cwtebay]

Not really sure where this upper even came from...... but now I have brass but no loaded ammunition.
I have some 300gr powder coated cast that I am thinking about using. Anyone have experience with using them?
Thank you.

I use a 315 grain PC'd slug in mine. Works a charm under 27 grains of Lil'gun.

WW 296 and H110 are great powders for 458 Socom but really love "Lil Gun" GW

What sort of velocities are you fellas going for with this load?
Are there any changes to be made to your buffer with this cartridge when using a standard off the shelf lower?

This is my first venture into bigger caliber loads for the AR 15 BTW.
