Does anyone have a recipe for this? The bullets are from MBC. Lee doesn’t have any data for this combo, couldn’t find anything on google. Thanks for your help!

Perhaps not a good match? I dunno, the Alliant database only lists the Speer GDHP using Unique.

My Loadbooks lists a Unique load using the Lyman 115gr lead #358345 bullet using Winchester case and primer:

4.5 start gr - 1025fps - 22,200 C.U.P - 5.7 MAX gr - 1210fps - 31,500 C.U.P.

There is also listed a load using RCBS 115gr lead 09-115RN at 5.2-5.7gr of Unique

I make no claim as to the viability or safety of using the data I have just typed. While I DID triple check it, I can't guarantee it.

Thanks for your help, exactly what I needed!

Alliant used to have lots of data; they gutted their database and left only the Speer bullets.

With 9mm, the bullet seating depth is critical. What is the exact length of the bullets, and what overall length are you loading them to? (from that it's easy to get the seating depth) Without that info, 5 to 5.5 grains of Unique still sounds about right. (I prefer Bullseye powder in 9mm)

The Loadbooks data lists a .997 OAL for the Lyman bullet, oddly enough it does NOT show an OAL for the RCBS. I checked my Lyman 49th and there are no 115 gr lead loads shown, only a jacketed HP at that weight.

These are the bullets I have:

They are .54 in legnth, I was going to go for an oal of 1.10 with 4.5 of unique.

Does this sound good?

They are .54 in legnth, I was going to go for an oal of 1.10 with 4.5 of unique. Does this sound good? That sounds a bit low, but it'll work. I would start at 5.0, and if it was a good load I'd stick with it. But I can't fault you for working up cautiously :)
