plated bullets for 10mm

[smle-man]

A friend gave me several thousand .40 plated bullets 155 gr FP. I have a SW 1006 10mm which I will use them in. Reload with them as if they were lead as far as powder charges go?

Yup.

Note the listed velocity on the load data though. Berry's for example, lists 1250 fps as max for their regular plated and 1500 fps for their thick plated. With 155s in a 10mm you can easily hit at least that first number. If you know the manufacturer, they typically have a FAQ entry on their site with recommended maximum velocity.

Have been using Rainier plated 180Gr bullets at 1200fps in G20 with 6 inch KKM barrel (fully supported chamber) with good results. I think these are the thicker plated bullets.

The new Lee manual has data for copper plated bullets, including plenty of choices for 155gr 10 mm and .40 cal. Gitcha one! :-)

p.s. Nice friend!

Actually no . It does depend on who makes them . For what ever reason Rainier says use lead data while Berry's say any jacketed data is fine and in fact suggest starting in the middle of the min/max of jacketed data .

Lots of theory's as to why . One is to use lead data because plated bullets are softer then jacketed bullets and more like lead in that respect . Also by using lead data you will tend to keep the velocities down as recommended by most plated bullet manufactures . While others say pretty much the opposite and that plated bullets are harder then lead but softer then jacketed . So you can start them at higher charges then jacketed bullets because they swage down into the rifling easier reducing start pressures that jacketed bullet create as they are forced into the rifling . Then there's the possibility that Rainier and Berry's have very different bullets in how hard there lead is and thickness of the plating resulting in different recommendations in load data .

I've found it interesting to research it a little but have not came to any concrete conclusions . Likely because this type of thing is a bit above my pay grade . So I just stick to what the individual manufactures recommend .

I'd agree with others that say using that light a bullet in this cartridge will get you to the platted bullets general max 1200fps pretty fast so keep an eye on that . This will also make these loads some nice plinking rounds IMO.

Experimented heavily with Xtreme 180 grn. While I couldn't get to full house loads without picking copper out of my teeth, I safely went well beyond lead projectile data. feel free to work up slowly, most plated Bullets are supposed to survive past 1200 fps but I found that was about the point where the plating started to disintegrate. On a curious note the accuracy didn't seem to suffer at pistol range.

Dark mod, did you mess with the heavy plated made specifically for 10mm? I've loaded a shot a bunch and accuracy was always fine, but I didn't do any REALLY hot loads, just standard higher end 10mm loads.
