Value of trimming 38 special brass for the Model 52

Anyone have any experience in the value or not of trimming 38 special brass for the Model 52?  My thoughts are since the 52 requires a 148 gr HBWC seated flush with the case mouth and then crimped, it seems as though this may contribute to the uniformity of the OAL. Any effect on accuracy and reliability appears to be maybe positive? Your thoughts? 

I realize this adds one more step, but I'd use a dedicated press like a Hollywood single stage or RCBS Rockchucker with a CH power trim die with either a Dillon power trimmer or a Fast and Friendly Bosch Router Carbide Bit set up. The CH power trim die is identical to the Dillon trim dies; .38 special requires a extended shell holder which is the reason I'll use a single stage press. Too bad, the ultimate power trimmer end all is to use a Dillon RL 1000 case processor, but the extended shell holder requirement negates its use.

Thanks in advance.

All cases end up the same length if you roll crimp. All complete rounds end up the same length depending on quality of seating die. Sizing is a step you don't need to do. IMHO

No sizing?

I size all my 38 brass. Unlike rifle brass pistol brass does not grow in length when resized. My experience has been the opposite if any change is noticeable.

My guess is the only real value is that it makes me feel better.
Once I muddled my way thru getting my reloads to work in my 52, I  carved the process into my stone like head.
The only pistol case that gets more attention would be my 7-TCU.

I think you meant "trimming is a step you don't need to do."

Please tell me more about this.

(Against my better judgment, I've recently started reloading .38 Spl. for a semiauto. Pandemic done made me crazy.)

Yes, I meant trimming. Oops

Len is likely right, because he has shot a few rounds out of a M52. I read somewhere if you trim to a certain length they run better? My guess it is a one an done type of operation. 

Once I established a magic load I would order some Remington brass and dedicate that brass after sized for matches and then use scrap brass for practice.

The only way to know for sure is to load trimmed brass and machine rest test the pistol at 50 yards. Everything else is just guessing.

I am not talking about trimming for accuracy but for feeding and reliability.

I trim all my cases for all my guns to a specific length, but then as a 1,000 yard benchrest shooters I am anal about reloading.
