Anyone here able to help with Speer data on the .357 147gn. gdhp? My latest Speer manual is the #12. I picked five boxes of these at closeout, dealer stated they were discontinued. Data probably in the 13 or 14 issues.
Thanks for any help you may be able to provide.

That bullet is designed for the 9mm or 357 SIG and has no cannalure to crimp into. There is no data in any of the Speer manuals for it in the 357 mag, and I doubt it is a very good choice for your cartridge.
Also it is still in production or at least is listed on the Speer web site.

Speer once made a 146gr Speer Hollow point it was a SWC design, haven't seen any of those for while.
Like Ol' Joe said, you have the wrong bullet for your cartridge :(
If they measure .355" dia. that would confirm they are not for .357 mag.

The bullets I have are labeled .38 spl 147 gn .357 gold dot hollow point, thelabel also says Uni core and they do have a cannelure. They are not the old, now regretfully discontinued hpswc that you crimp over the jacket, used those for many years and now down to my last three boxes. I believe the Speer product number is #4016, as that is printed at the bottem left part of the label next to "100". I have quite a number of Speer manuels up to and including the #12, but they must have been listed and discontinued during the era of the #13 and #14 manuels, as none of the manuals I have list them.

When I get home tonight (will be late) I'll see if I have that bullet listed in my database.

AA#7 should be a good powder. It's just like Blue Dot without the drama.

I have Speer #4002, .355" 147 grain GDHP. Also #4205, .357" 146 grain JHP. They are only .010" different in length.

These are just predictions not necessarily based on good assumptions (so be careful), but the Bullseye, Unique, Herco, and AA#7 all look pretty good to me:

Cartridge : .357 Magnum (SAAMI)
Bullet : .355, 147, Speer HP GD 4002
Cartridge O.A.L. L6: 1.590 inch or 40.39 mm
Barrel Length : 5.5 inch or 139.7 mm

Predicted Data for Indicated Charges of the Following Powders.

Matching Maximum Pressure: 32000 psi, or 220 MPa

or a maximum loading ratio or filling of 105 %

These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

Thanks for the data. Not the same bullet as the 4016 is .357 not .355, but it will give me a starting place. Will also call this morning and see what Speer has to say.

mystery solved.

Finally got Speer tech support today (called two other days, left messages, no return call).
A very nice lady informed me that Speer had a load sheet developed for this bullet, but it had been introduced and then the decision made to drop it in such short order that it never made it into any Speer manual. She offered to email me the data for the 357 mag. so if anyone else runs into any of these bullets (product #4016) I would be glad to send a copy on to you or you can get it from Speer (if you can get ahold of them).
Thanks to those who attempted to help,
Olevern
