rainer suggest you either use lead loads or take loads for FMJ and reduce powder by 10%.

Thanks for the help everyone, gonna try the reduced FMJ loads like on the Ranier website and see where I end up.

plated or jacketed lead is a nonissue since the plating or jacket protects the lead from contacting the bore. In essence, if you can shoot jacketed, you can shoot lead. FWIW, Speer Gold Dot bullets are plated bullets. They are not jacketed

Coupla points Adam ........ I had thought Raniers were only ''copper washed'' - which would mean the most minimal of copper deposition? I guess I'd need to use them and recover a fired result to see that engraving did not make it thru the copper layer.

Re Gold Dots ..... plated? I had not realized that but am confused as when looking at test bullets ... see the left example in the pic ... there appears to be actual copper showing at the end of one ''petal''. Not trying to pick holes but somehow can't see these as only plated.

Copper washing is another term for plating. You submerse the lead core into a copper bath and charge it with electricity which forces the copper to adhere to the lead core.

The Gold Dot bullet's jacket is a jacket formed by plating over a core. The bullet core is seated into this jacket in the same manner as any other jacketed bullet, however it is still plated. Because it has a core seated in a jacket, ATK (who owns Speer) calls this a jacketed bullet, but technically speaking it is a plated bullet. The jacket is made by the process of plating and the core is seated in this jacket.

ETA: I've run Rainier plated up to 1450fps from my 10mm and there was no issues. Rainier recommends velocities less than 1200fps.

Gotcha now - I should have tried a scratch test which will usually show plating for what it is. I can see a good saving on not using full thickness pure copper - so what we have is what I think of as a ''guilding'' ....... just the external surface.

Quite a contrast compared with Barne's all solids - they are machined from solid ... spendy, but seemingly very effective.

I would just use data for lead bullets.

Tubby's right . Perfectly safe to shoot plated in a glock. Take a razor knife and cut up a plated bullet. The plating is plenty thick for velocities up to 1300 f.p.s.
