Bullet Recommendation - 38 SPL

[Karl]

I am new to the world of .38 special. I just purchased a .357 magnum revolver with 6.5" barrel. I intend to use this for target shooting at 25 yrds. with .38 special. I will likely use Power Pistol or Blue Dot simply because I already have it. I understand that lead bullets are more desirable in revolvers. What are recommended bullets? weight? coated?

Thanks.
