I picked these up at a gun show at a decent price. I cannot find load data for these bullets. They will be shot in two .357 mag. A 686 4" and a 640 J-Frame. I have some Win 296 and a lot of H-110 on hand. Anybody have a source or a load they can share?

Bullets are Speer jacketed hollow points. #4205

I'll need O.A.L also.

Thank you!

The only 146 gr. .38 bullet I am aware of that Speer ever made was the semi-jacketed hollow-point semi-wadcutter. A #4205 is not currently listed. Is this the bullet you are asking about? If it is then:

Use 150 gr. loading data.

Forget about LOA, crimp over the front edge of the jacket.

While on the subject, with any handgun cartridge you are going to crimp, simply seat to the cannellure and crimp there, forget about LOA, it doesn't mean anything, especially with revolver cartidges!

I wish I had my Speer #9 handy, but it's in deep storage. It probably had some data that would help.

That is THE bullet I am inquiring about, and it is not listed as it has been out of production for quite a while. Thank you all for your prompt replies. I am now off to the reloading room. Going shootin' in the morning. Thanks again.

The older Speer manuals listed data for the #4205 bullet in the 357
magnum but the current ones don't it seems although they do show
data for 38 spl +P. My Lyman Pistol and Revolver manual lists it for
357 with H110 with 17.0 grs as a maximum charge.

I loaded those in my M19 6" up to 1296 fps with Blue Dot, many years ago.
Ran out of them and only have a few 160 gr bullets left.

The 146 is a very accurate bullet but like the 160.........
once you crimp the bullet it is a done deal. Do NOT try to pull
this bullet..... the lead will come out but the jacket will stay in the case.

My OAL was with the case swallowing all of the copper jacket
with a medium to heavy crimp.

Enjoy those bullets.

I loved those old Speer 3/4 jacketed swc bullets. Found a bunch of them in the 200 gr. HP for .41 mag a few years back and shot 'em up in my 3-screw Ruger .41s.

Speer #10 manual lists 16.2 - 18.2 grs of H-110 with the 146 grain bullet in the .357.

I don't shoot H-110 so not sure if this applies, but burn rates on some powders has changed a bit over the years (2400 as an example - a bit hotter than it used to be), so I'd start at the low end of that and monitor results since this manual was published in 1979.

Just found a half box of the Speer 38sp 146 JHP, but don't have a old Speer manual. The bullet is discontinued and isn't listed in anything that I have. I'd like to use either Unique or Bullseye, and makes no difference if it's 38sp or 357. I read somewhere that there was a minimum velocity with these bullets to prevent core separation. I just want a mid-range recipe. Thank you as always.

Speer Reloading Manual Number Ten

146 GR It just says Hollow Point but the picture indicates SJHP SWC

.357 Magnum Loading Data:

H110 = 16.2 (1361MV) to 18.2 (1465MV)

W296 = 16.5 (1351MV) to 18.5 (1513MV)

Primers for H10 and W296 were specified as CCI 550 Magnum Primers
---------------------------------------------------------

Unique = 8.0 (1279MV) to 8.5 (1363MV)

Bullseye = 6.7 (1166MV) to 7.2 (1353)

There was no primer specification on the Unique or Bullseye.

-------------------------------------------------------------
-------------------------------------------------------------

38 Special Loading Data
(There was no H110 or 296 loading for 38 Special)

Bullseye = 4.5 (902MV) to +P 5.4 (1029MV)

Unique = 5.0 (871MV) to +P 5.9 (1048MV)

There was no primer specification on these 38 Special loads.

A Note at the bottom of the page states that for this bullet the lighter charges listed for the 38 special loadings should be considered minimum due to a risk of the jacket separating from the bullet and lodging in the barrel due to it's straight sided jacket. The same warning applies to the similar 160GR soft point.
(I don't understand the warning as it seems counter-intuitive to me but it's there.)
---------------------------
As previously stated roll crimp over the forward end of the jacket.

Velocities listed in the book were out of a 6" Ruger Security Six.

A 1960's era Lyman manual lists the following with Unique and that bullet.

.38 Spl=4.5-5.6 gr

.357 Mag= 5.5-8.5 gr.

OK, reading back over the thread you DIDN"T ask for middle of the road loads with Bullseye or Unique. My quick recollection is no data for H110 in that manual. Those bullets really weren't intended for max velocity loads.

If you go to the Hodgdon website they have load data for the 146gr Speer bullet.

Thanks everyone for the advice / comments. Helped greatly, and now they can be put to use.

Hodgdon has data for that bullet in their online load data site. Like said above, revolver bullets should be crimped into the manufacturers supplied crimp groove.

I have used those in my model 27 357, I was using what ever the max load in my Speer #9 manual with w296. They shot very accurately but the full house 296 loads are a bit extreme and I can't imagine shooting them in a shorter barreled revolver.

Speer Manual #8 - 1970
146 gr.Speer Hollow Point SWC ( it has a 3/4 jacket)
no bullet # is given and no OAL is listed( in 1970 few of us had calipers to measure with ) .
357 Magnum
H-110 powder
CCI 550 magnum pistol primer

starting load 14.0 grs. = 1151 fps
15.0 grs. = 1381 fps
maximum load 16.0 grs. = 1365 fps

This bullet has no cannelure or crimp groove , we roll crimped just over the front edge of the jacket...where the bullet jacket stops and the lead SWC nose begins. Looking at a loaded round it appears to be a lead bullet, the jacket is inside the case and can't be seen.

Start low and work up . Look for signs of excess pressure.
Some of my best pet loads come from this manual.
In 41 magnum these 3/4 jacketed hollow point SWC's were catastrophic on soft tissue and the 3/4 jacket held together for penetration...still one of my favorite bullets .

I still have a couple of boxes of 357's that I reloaded with those bullets, they are really accurate in my model 27. I used w296 and mag pistol primers with a load listed in the Speer #10 manual. I noticed that in my #12 manual they had reduced the max charge by about 1.5 grains. Accurate but the muzzle blast with 296 is pretty extreme.

Running them at low velocity can cause the jacket to separate and possibly end up in the barrel. I'm sure that's why they were discontinued.

Bonding wasn't nearly as good in those days.

I've been using same style bullet which this is 158gr loaded in 38 special +P cases using 9.0 gr of 2400 powder with very good results. Using load data from the Lyman 50th edition for jacketed bullets.

I liked those old 3/4 jacket bullets. SWC design, soft lead for expansion, jacket prevents leading. All good. I shot these in .357 in both 146 and the 160 (same design but no hollow point) for years till discontinued. I found a few boxes of that same design bullet in 200 gr. .41 and 225 gr. .44 a few years back - in the old yellow hardboard boxes with metal corners. I got to wondering when the transition to plastic boxes happened ( when I started reloading in the mid-70s they were already plastic) so I emailed Speer and asked them. Told them I'd just found a few boxes of those in a sporting goods store. The Speer guy's response was priceless - he said "I think late 60s or early 70s - don't buy any dairy products from that store."

Wow......
Alcan powder !!

How old is that manual ?

That looks like the Speer manual I had in the mid 70s. I used to shoot AL 7&8 back in the day. It was old even then.
