38 Super Reloading Cocktail

Looking at reloading 38 Super using Berrys 124g TMJ copper bullets and Accurate #5 Powder. What minImum grains do I start with? Is it ok to use FMJ grain data for TMJ bullets loads?

This from the Western Powders manual:

Go to the manuf website and they'll have some load data for you. FMJ/TMJ are technically the same thing so use the same load/charge weights and data.

I never use "forum load data" so my suggestions are look in your reloading manual(s). From the pics and links above dependable, published load data is readily available. And before you buy any components find a load, with primer, powder, bullet and load data, preferably right out of your manual. Not being snarky, just an old guy's advise/experience...

Go slow. Double check everything. K.I.S.S. Most important, have fun.

Although Berry's specifically has 2 different types of plated bullets... a "regular" plated, which is not rated to stay together over 1250fps and a "thick plate" which is fine up to 1500fps. Since this is a 38 Super thread, the difference may come into play.

Why start off with plated bullets and a fast powder in .38 Super? Might as well shoot 9x19. For accuracy (obviously not important if using plated bullets), look to Silhouette or AA7. For plinking fun, might as well go with Bullseye—very consistent and well-behaved unlike AA5.
First, get a Western Powder manual for AA powders.

I've shot well over 30K Berry's plated bullets out of .38 Supers and find them no different than jacketed or TMJ bullets. Any data you can use for one type you can use for any...as long as the bullet styles, RB, TC, etc. are the same.

Every bullet is going to have it's own LOA which is going to effect pressure and feeding... All one can do is slowly work up a load for an individual gun....

I've burned up a lotta AA#5 over the years, reloading calibers from .380 ACP up through .45 Colt "+P", and never found it to be terribly inconsistent. I guess it depends on one's definition.
To get the most out of a .38 Super, other propellants may be better. But to merely operate the slide on the pistol and obtain .38 Super-level velocities, and in the absence of other propellant choices, Accurate #5 isn't really misplaced in a .38 Super.
I'm VERY much in agreement about seating depth being a big determinant of chamber pressure. It tends to explain why a (necessarily) longer JHP projectile may be loaded with lower charge weights than an equal weight FMJ loaded to the same overall length.

Plated bullets......

I know some plated bullet mfg's have a thicker plating for higher MV loads....like when shooting USPSA to make Major with 9mm.

Many years ago I tried plated bullets, and was not happy with the accuracy, so I have always purchased JHP bullets, and have had very good and consistent accuracy with Zero and Precision Delta truncated JHP bullet styles.

Unfortunately, with the pandemic, there just isn't a great deal of ammo at retail, so many people have started reloading.....and there is a shortage on bullets and primers...... I think some bullet makers are saying an order may take 6-8 weeks or longer .....

Western Powders lists 2 loads in .38 Super, using AA#5 and 147 gr. bullets, which deliver velocities well into the "Major" zone, but still under the 1250 f/s upper limit for plated bullets.
I realize that 147s are not what the O.P. asked about, but it represents another possible option for them, should the 124/125 gr. projectiles become scarce(r). I can't think of anything a 124gr. bullet can accomplish that a 147 gr. bullet can NOT, and with lower powder utilization.
I guess the exception might be a .38 Super equipped with a muzzle brake, in which case the use of AA#5 is also problematic.

We all have or range loads, and go to rocket fuel. I don’t normally list cocktails but my go to rocket fuel is 115 gr jacketed round nose over 10.0 grs.of Accurate #7. Meters very well & and truly has some legs. Cheers!

Haven't tried AA#5 in 38 Super because I use it for other calibers.
Love the 38 Super and my favorite target loads have been with 115gr
E-xtreme FP and Titegroup powder. Getting 1250fps and the accuracy is wunderbar. Other powders I have tried with Hornady Hap or XTP bullets are AA#7, Power Pistol and VV-N105. The VV-N105 with a 125gr. XTP bullet delivers a consistent 1450fps. out of a DW PM-38 5".
Hope this helps.

Well damn Iíll definitely need to do more homework. So is it fair to say that this is in the ballpark? 124gn/AA5: 6.7-7.6gn.

All I can find is +P data, which lists 7.2-8.0/AA#5/124. Your starting loads may be so light that the slide won't operate fully, so make small batches in which you increase the charge weight 0.1 gr. per batch. Once you get reliable cycling, you might increase the charge weight one more tenth of a grain, just as insurance against random factors.

After that, I'd quit with the work up, if you're just looking for a practice load. Once you have a load combination that works, make a bucket-full and go shooting.

You are the man, thanks for the feedback. Cheers!
