Bought some off gun broker. Wood powder you guys think would work best?

That is a lite round for 10mm.  I'd try universal or tightgroup. Starting about 7gn.  Why those bullets?

I got them cheap ($51/k shipped).

What is the length of the bullet?  Yes it is light but it is the length that will occupy case capacity.  You will likely be between the 135 grain and 155 grain for most loading data...

Shadow nailed it.  Figure out what length goes in the case and use the load data for a standard copper/lead projectile that is a similar depth into the case.  Work up from there.

When they arrive I'll get some measurements and update. I was thinking of starting at 8 gr of Long Shot. Not sure that would be enough to cycle my G29. I've bought 9mm plated bullets from this outfit before and ended running all 2k through a Lee sizer to get them all down to 0.356". Some measured 0.3575" and I loaded them with max charges of Titegroup...

Hoping the advertised diameters are true on these. Not certain how much margin for error to expect on a monolithic bullet without relief bands cut.

You will likely find 10.0 grains of LongShot to put you at 1500 fps, based on 155 grain bullets being pushed at that charge weight.
That will probably be a great load based on the lighter 105 grain weight of the Monolithics...
Just to get a better understanding I have seen some data with 155's using 10.5 of LS but some did report Smiles in some chambers at that level...

Those are supposed to be made from Copper, Nickel, and Tin. I wonder if they would wear the barrel faster than regular bullets.

Well, I got my order in today. Their diameter is spot on and the overall length is approximately the same as 165 gr FMJ... as far as hardness goes, they smash down with a hammer about the same as hard cast lead. Doesnt look like the vendor is selling anymore 10mm or 9mm, but still has some 45, might bid on 2k of those.
