Cast vs. plated

I use plated, cast bullets in most of my reloads. However, I have very little data to indicate the best start/max load. The Lyman Manual has good info on jacketed bullets but none on plated. My Lee manual has some data but not much.
I get a general sence that less of a charge should be used for cast bullets of the same weight as a jacketed bullet. Does anyone have a general "rule of thumb" regarding how much less?

If they're plated they aren't cast. I load plated bullets according to jacketed figures with no issues.

Plated should start with the same as cast data. Berrys says theirs can go to the midpoint of jacketed data, and I've had very good luck with Berry's products - more coming in soon. ;)

I use jacketed data for Berry's loads also. The plating is good to up to 1200fps on the thin plated bullets and the thick plated is good for up to 1400 according to Berry's web site.

I don't load my full house magnum loads with the thin plate bullets though, thát's going a to far for me.

Very true but when the manufacture says they get the best results with jacketed data then why would you use cast data? I also use jacketed data with Berry's and Rainier.

You really should stop telling people this. Not all plated bullets should be considered equal. It may have been true years ago, but plating technology has changed and not all plated bullets are the same. Berry's sells some of the thinnest plated bullets on the market. Others such as xtreme and powerbond are almost as thick as speer TMJ. They should be loaded using normal jacketed data. Though I should say that in some revolvers it won't matter what data you use. If the forcing cone doesn't like plated bullets, it will shave plating no matter what.

I will keep saying what has worked for me- if yours doesn't then let the world know. :) Berry's are the only plated bullets I used, and they work very well for me in 9mm and 7.62x39mm.

I am not the worlds greatest shot by any stretch, but that works for me.:cool:

Maybe you should consider telling people to use lead cast data for Berry's bullets instead of for all plated bullets since you don't have experience with other brands of plated bullets.

With the Berry's 9mm 125 gr RN and their .45 cal 230 gr. RN, I have charged them just shy of the published max jacketed load data with great results.

But... I will always check the prices for Zero Bullets at Roze Distributors, as it's not uncommon to find the jacketed Zero bullets for the same or less price than Berry's.
