Hi folks, I took my Model 52 to the range today and some reloads which were very accurate but would not cycle the slide and eject the spent casing. The load is 3.0 gr of HP38 with a 148 gr LHBWC bullet, minimal crimp. Est FPS = 770. Ideas? Does anyone use HP38 and if so, how much are you using? Thanks for your help.
Reload does not cycle slide... seeking advice

Sounds like that is a light load. It may not have the energy to cycle the slide.
Two choices: change to a lighter spring or put more powder in it. You are using a minimum load, which is fine in my revolver, but in a semi-auto, you have to have enough energy to work the "machine."
I don't know how you are estimating the MV, but I load 3.0 HP38 and measure the MV from a 4" Model 66 with a chronograph, more like 690.

Kind of a no brainer, you need more energy. Your current load should be enough so first, double check how you are measuring to get that 3.0. If you are confident it is correct then move up til it functions properly.

Yes, bump the charge up a bit, that's all it needs.
Hodgdon says 3.5-4.0 HP 38 for a 148 gr. LHBWC. Perhaps 3.0 is too light to cycle the action...

Make sure it is clean. That load should work. If the slide is nice and smooth try a lighter spring. Have you had it long? That is a top load unless the slide is heaver than factory. Bullseye powder has a little more punch. I don't think many 52 owners load that hot. It was designed for 2.7 of Bullseye. A small roll crimp or a tighter crimp will bring the pressure up a little. Try a bullet without the magazine to see if it will eject. With the right load the cases will eject 3 to 5 feet. 700x is a good powder for the 52 also. Data for a 52 is different from a revolver on powder charges.

I second above. A tighter crimp would help. If you are shooting a load that is too light then that is another problem With a semi-auto you should not need a tight crimp but, couldn't hurt unless you do both.
A heavier crimp should up the fps of a load but it will also decrease the life
of the cases, over working them.
One of my manuals shows 3.0 grs of w231 at 700 fps for a starting load for the 148 lead wc bullet.
Another manual shows 725 fps as a starting fps for the M52.
Match the load to your spring, until the cases land 3 feet or more from you, for a starting load. A chrony is not needed with a factory stock spring, in a well used pistol.
w231 powder does not have as much energy as some of the other faster burning powders and usually needs a little more to get the job done, in 38 loads.
Even in my small 9mm cases, my lowest amount of w231 used is 3.5 grs of powder for a 147gr bullet.
Good loading.

3.0 gr of HP-38 is too light a charge for a Model 52. My best/most accurate load for "my" Model 52-2 is 3.6 gr of HP-38 for the 148 gr HBWC. About 870 fps. Trim the cases and load the bullet flush with the case mouth with a slight roll crimp to eliminate any feeding problems.

Mod 52 Load
My 52-1 ran fine on 3.0 of HP38 and a 148 gr WC. But I bought it used and don’t know if any modifications were made. Willyboy

I had the same problem with the first 9mm rounds I loaded with AA#2 not cycling my P94DC. Bumped the charge up a tenth and no more problem. 
I don't have a model 52 but do have a 1911 in .38 special. My go to load is 2.8 gr Bullseye (2.7 wasn't quite enough to cycle 100% reliably). When I experimented with W231, I settled on 3.2 gr. That seemed about equivalent to 2.8 gr Bullseye.
I personally wouldn't mess with crimp. I don't crimp mine, or more specifically I have the crimp die set to take out the case flare but not apply a roll crimp. If I had a taper crimp die for .357 I would use that.

Thanks for all the advise folks. I will try 3.5 grains of HP38 after double checking the measurement of the 3.0 grains I used in the initial loads. I'll also check the crimp just to be sure everything is ok there. Have lots of yard work to do before the snow flies here in Ohio so I may not get back with results any time soon but I promise to let you know how the increased amt of powder works out. Thanks again and stay safe.
My Model 52-2 likes hollow base wadcutters seated flush, with barely a crimp and 2.7 grains of Bullseye. Any less than that it won't cycle reliably

It may just be me, but...
I would think using enough powder to insure the slide always cycles reliably would be almost as important in a firearm designed to shoot (for the most part) a single design of a bullet (wadcutter) @ a medium velocity, primarilly in a target environment, as it would be in a more general usage, i.e., plinking, carry, home defense, small game, etc?
That said, has anyone had any experience in using the Federal 130gr JHPWC Micro HST +P in either the factory loading or reloaded (as per quite a few threads on this forum) in their Model 52?
Cheers!

The 52 runs at 700- 780 fps. Wad cutters is all they will shoot.

Uh, that bullet...
That bullet is a wadcutter: I was not aware that there was a fps limit on the Model 52. Thought that HST might be a pretty good SD or HD choice for it...?
Are the medium to MAX loads for the18 powders listed in Hodgdons all too hot for a Model 52?
Cheers!
P.S. 3.0 grains of Bullseye might be a "top load" for a148gr lead wadcutter but it is not for the HP-38 (WIN231?) load the O/P initially inquired about.

I use 3.1 to 3.2 HP38 depending on powder lot burning rate . Remington or Zero 148 HBWC , Fed 100 primer , seated flush with case mouth & taper crimped to .369 .
