Since you want too shoot GSSF go with the Berry 200gr bullet. I use 200gr X-treme bullets. Also since you want too use WST try 4.4gr at 1.120-5. I have not tried this load yet but I got it from Ed that also shoots GSSF. This is the starting load for a lead bullet and 5.1 is max.
You do not need a 230 gr. Bullet. For one they cost more.
Welcome too reloading and GSSF.

Shooting is merely a byproduct of reloading.
