PP Bullet for My New 38-55

[Flash Pan Dan]

Thank you so much for your responses. I am currently using a Utrecht Tracing Paper, 8.0 lb, and when patched dry it adds .00535 to my 40-65 bullets made out of pure lead. I use pure lead in that rifle because it is not a PP chamber but it can hold 1.5 MOA at 200 yards.
Powderburner, would you elaborate on the alloy having a determinate factor on the bullet diameter? I am planning on using a 16:1 or 20:1 alloy to start with.
