Is the load below sufficient for an accurate load?
rainier 230gr tcj
5.7-5.8gr of cfe pistol powder
CCI LP primer
COL -1.25/1.26
That's in the lower-middle range of Hodgdon's published charge weights for 230gr projectiles. As for accuracy (and velocity), your mileage will vary depending on other factors you aren't articulating, e.g., your gun. Having loaded and shot a fair quantity of 230gr bullets with CFE pistol, both FMJ and coated, I would expect 5.7-5.8gr loads to be light loads (which says nothing about accuracy per se, which was your question).
Get yourself a CURRENT copy (the 50th anniversary edition is the newest one) of the LYMAN load data book. Nobody has more load data for lead bullets than they do. You can safely use LEAD load data for any copper plated bullets, or (of course) lead bullets.
