I recently picked up some Berry’s plated bullets, 10mm 210gr flat point (which I can’t even find on their website). As usual, I buy the bullets before looking to see if any reloading data even exists for them. :banghead:
I know I should load them using lead bullet data, but none of my manuals have this particular bullet weight. I’m looking to make some moderate power practice loads, nothing too hot.

Can I use data for 200gr lead bullets, is that ‘close enough’?

Bonus would be someone who has developed a load for this bullet.

Use 200gr data and work up. I have a custom 225gr LSWC I cast and load with 5.5gr WSF in the 10mm just fine.

I know I should load them using lead bullet data,How do you know this?

Berry's website FAQ says:

Plated bullets occupy a position between cast bullets and jacketed bullets. They are soft lead, but have a hard outer shell on them. When loading plated bullets we have found best results using low- to mid-range jacketed data in the load manual. You must use data for a bullet that has the same weight and profile as the one you are loading. Do not exceed mid-range loads. Do not use magnum loads.

Thanks all! I guess I'll just have to experiment a little.

You must use data for a bullet that has the same weight and profile as the one you are loading.

Do you think they're sitting around laughing at me for having purchased a bullet weight for which no data exists? 210 gr indeed!

Anyway, here's the new pistol:

210 gr indeed!Berry does in fact make a 210 grain bullet.
But it is a .410" bullet for the 41 Magnum.
Not a .401" bullet for the .40S&W /10mm.

I'd strongly suggest you double-check the box label, looking for any possibility of dyslexia. :D

And also get out the calipers and measure some of the bullets and make absolutely sure they are in fact .401" bullets, not .410" bullets.

Excellent advise.

Ditto to RC...
They are NOT bullets for the .40/10mm!

(unless I am sadly mistaken, of course.)

That's a falsehood if I've ever seen one.

[rcmodel]

I wouldn't go so far as to call it a falsehood.

Berry's, the load manual publishers, and us on this forum have to assume we are dealing with folks who have never loaded a round in their life before.

You wouldn't want to tell them to just find some load data for something, and use it with whatever bullet weight & profile they have laying around.

Would you?

The way the statement is written is inferring that is the only option in the world and OMG if you are trying to load 190gr Sierra JHP instead of 180gr Hornady XTP it will cause the world to end.

If you "must" something, that is a totalitarian statement to where there is no other option. In this case there are other options and to ignore them is ridiculous.

I have the current Berry's wholesale price list and catalog here in front of me. They don't list a 210 grain bullet in .40/10mm, and to the best of my knowledge, never have. Only in .41 caliber do they list a 210 grain plated bullet.

I've been loading Berry's plated bullets for over 10 years, and I've never seen a .40/10mm plated bullet from them in the 210 grain weight. The new list doesn't even show any 200 grain bullets in .40/10mm, though I have a couple thousand of them in stock.

As for the loading advice, I would rather have new reloaders err on the side of safety, rather than just going off willy-nilly into reloading land. I experiment all the time with different loads, but I've been at this since 1963, and have loaded over 3/4 million rounds (as close as I can figure). For a new reloader to just dive in and start exchanging components, without considering the cause and effect of doing so, would be unwise and possibly unsafe. The key words are "cause and effect". Without an understanding of that, then a new reloader should stick pretty close to published data. An experienced reloader, who understands cause and effect, will be able to vary components, within reason.

Hope this helps.

Throw Barnes solid copper bullets, Nosler Partition-HG bullets, jacketed bullets, and plated bullets in the pot and shake it and the idea of interchangable data doesn't sound so hot to me..

I'm almost too embarrassed to admit it, but they're actually 41s not 40s. I went back to Cabelas and, yup, someone put the 41s where the 40s go. I looked at the shelf, saw 40 cal, then at the box and saw 210gr, and dropped them in the cart. I don't know why they use such tiny print, but I also can't blame them for my mistake. So now I have to unload these 41 cal bullets or buy another handgun.

[ReloaderFred]

I'm glad you discovered the problem. I didn't think they were the right bullets for .40 caliber, since I'm pretty familiar with the Berry's line of bullets.

I've used either bullets or ammunition as an excuse to buy several firearms, so getting a .41 sounds like a viable alternative to me...........

This could be a win-win proposition!

so getting a .41 sounds like a viable alternative to me...........Yep, nice caliber. :D
