Hodgdon says 2.7-3.0 for berrys 124 HBRN TP. Lyman says 3.1-3.6 for 125 JHP. LEE has 3.5-3.7 for 125 JHP. And 2.9-3.3 for 125 LRN.

Anyone shoot 124 xtreme plated RN with clays?
 
Curious to see any replies here. I've just loaded my first batch of these bullets using Unique, but I have a boatload of Clays that I would like to use up for the next batch.

Never used Xtreme bullets before. They sure are pretty coming out of the box.
 
Treat the plated bullets like lead not jacketed and you will be fine. Great plinking ammo.
 
I have shot plenty of Berrys and Xtreme 124 PRN

For me, mid to high jacketed works best as they seem to need more umph than just lead data to cycle and be accurate.

If I were you and I woke up in your shoes tomorrow, I would start at 3.0 and plan to work up from there in 0.2 increments.
 
I use berry's 124gn with W231 using lead data up to mid-range jacketed. Berry's plated is good to 1250 fps so you can extrapolate your charge range.

With a hollow base, you naturally have a bit more chamber volume, so your pressure should be lower. I don't know if the HB helps the bullet obdurate or what the exact purpose is.
 
I love clays in 45 acp and 38 special. It's my go too powder for those calibers. Given that (and the fact I have 14# of it) , I have experimented extensively to get a "go to" load using clays in the 9mm. So far I've fallen short with any bullet under 130gr. I much prefer solo 1000, Tight Group or HP38 for the 115-125 gr application.

That said, I have had acceptable accuracy using 125 gr Berry's plated RN bullets over 3.4 gr of clays. Personally, I would consider this my max load and watch OAL. Clays produces UGLY pressure spikes fast with just a couple of tenths of overage.
 
Ok thanks. Hopefully I can arrive at an accurate and functional load within the safe window. Kinda weird looking powder.

FWIW I've loaded about 10,000 of these pills under 4.6 Unique at 1.15". Great accurate and reliable load in M&P and P226. Brass isn't super clean but nothing I've tried so far is cleaner.
 
Works even better if you put the bullet on top of the powder, yuk yuk.

Clays is awful fast for 9mm.
I would start low and quit immediately I made Minor.
 
Sorry I can't help with Clays in the 9mm, I just don't use it there. I don't like very freeloaders in small high pressure cases, especially fast powders that can spike pressures at the top end like Clays does. When loading range ammo for the 9mm it's W231 for me.
 
Are the OALs different with the different data? That could account for some of the variance in the load ranges. Shorter OAL, higher pressure with the same powder load, so you will hit max sooner. I also use mid-range plated data with Berry's, or other plated bullets. Clays is a very fast powder and I don't generally use it in 9mm. If you have a slower powder you might find you like the results better.
 
Barry Bullets has short OAL recommendations which will have lower charge weight when compared to reloading data with longer OAL.
My loading does not follow any particular book as my OALs are longer to fit my chamber. Barry's OAL of 1.060 shoots good in my glock with 4.1 grains of HP38. When I set OAL at 1.090 with 4.2 grains, I get better accuracy with the same velocity. I did the same thing with Sierra 125gr FMJ. I took a book load at 1.142 OAL and stretched it to my chamber at 1.160. I added .2 grains to get the velocity back and accuracy also improved. I prefer to use faster powers with shorter AOL and slower powders on longer AOL
 
Well so far Clays is proving a bit of a PITA to load. At least in the LCT with PAD. I get light charges maybe one out of 10. Then sometimes it will throw 2 or three light charges in a row. Like 2 grains light. Fortunately due to the light color of the powder it's easy to see but you do have to pay close attention. I wonder if it's due to the slightly Curvy Potatochip shape of the powder or what.

Think Ball powders... W231/HP-38, Zip and AA#5 will do a great job. If for some reason you want a fast powder for loading the 9mm there is also AA#2. Just what I would be doing.

I use W231 for range ammo and with lead bullets and HS-6 or Longshot for more serious work.
 
tried 3.2 and 3.4 clays under 124 xtreme at 1.15". 3.2 obviously way too light. Multiple malfunctions in both P226 and M&P CORE and failed to lock slide back in either. Seemed pretty accurate in both, though. 3.4 was better but still failed to lock the slide and stovepiped once.

May work better under 147s. Tried it in .38 special under 125s with VERY erratic power/recoil and tons of scorching, unburned flakes and crud. So far it's not living up to the "clean" hype. However in 9mm there was very little unburned flakes, despite the very low power.

I'll try maybe one more step up in the 9mm and then save it for other uses I guess if that doesn't work out. I realize there are better powders for 9mm but I've been looking for a very clean load for shooting suppressed.
 
Your talking apples and oranges when talking the same load of clays in 38 and 9mm. Youalso cant just go to a heavier bullet with the same load. This is DANGEROUS territory. Pleas stop and regroup before going further.
 
I started loading 9mm with Clays back in 2014. Xtreme 124gr RN HP CB

3.0 gr was too light OAL 1.16"
3.3 gr was better.
3.4 gr better. Works fine and seems accurate.


These charges all seem to meter well in my Dillon 550b.

I have not loaded any 9mm on my LCT or my single stage.

X-Treme 124gr RN is the only bullet I use in 9mm anymore. I seat them to 1.135". I stick with slower powders that are better suited to the 9mm's pressure range. There's a reason bullet makers don't publish data pairing 9mm and Clays.

I've used Clays in 45 Auto and found that it meters poorly. This is a big concern with such a fast burning powder with a narrow range between start and max. Even more so in 9mm.

I use Power Pistol in 9mm with good results, clean and accurate. If you want really clean try VV 3N37 or N350. Fiddling around with a powder that isn't well suited for a particular cartridge just because you have it on hand for another one has always seemed like a waste of components to me. Better to use a powder that is well suited for it.
