 The powder to beat for the 358 Winchester.

By Frederick R. on Feb 21, 2026
I have had several 358 Winchester riflers over many years.
Years ago I settled on the Sierra 225 Gr Gameking as it has proven to be the most accurate bullet in any rifle of .358 caliber I've tried it in. In the 358Winchester, it is ideal.
I had developed an excellent load for my 358 years ago with this bullet and this powder.
it has since proven to be the load to beat in any 358 rifle I've tried it in, including my current one. I have yet to better it with any powder.
It is usually available and although an older powder, is still viable.
