40cal 165g using hp-38 Load Question

[PatC415]

Anyone use Precision Delta 40cal Bullets? I just received 1K of the 165g FMJ, FN. Just started loading 40cal. Heard about kabooms....
Load data is hard to find for this app, let alone 165g pills. Lots of 180g info.
I was going to try 1.125OAL, 5g of HP-38, CCI SPP.
Any thoughts?

Is Precision Delta a plated bullet or a jacketed bullet?

EDIT: I see they're jacketed. I'll get you some data.

I've been going over a lot of loading manuals the last week looking for 10mm load data on Xtreme 165gr plated RNFP (round nose flat point). I can look up some data for you and scan/ocr the document for reference.

AFAIK, plated bullets can't be push beyond a certain velocity (fps). The plating will separate prematurely and you'll get lousy accuracy.

Interchanging the JHP with your FMJ effects ballistics but start low and build up your load. Don't exceed maximum, which is 5.3gr. Your starting load from your OP is 5.0gr. Don't do that if you've never tested that round from your gun.

From what I've read, fast powder with a heavy bullet can cause some scary stuff. The powder is igniting fast and so gas is building too quickly to push a heavy round. Maybe not a KaBoom, but a very loud Bang.

I had one incident which I KNOW wasn't a double charge on a Glock 22. The round went off like a Magnum! Scared the poop out of me. The recoil was stout and violent enough that it dislodge the recoil rod. Good thing it was the stock plastic one because we had to flex it back into position to move the slide. I think it was a 180gr FMJ with WIN231. But I was within load limits. A double charge would have overfilled the case.

I load a lot of different rounds. I'm in your area.

I load all my .40 to 1.135. It gives a safety margin, and functions reliably in my gun. Im around 5k very safe .40 loads fired!

HP 38 is good to go for 40 cal and 9mm in an XD pistol. I don't count the number of rounds through my guns, but I must be somewhere around 20k to 30k (combined 9mm and 40 cal) rounds on my 2005 XD Service bitone.

My favorite two bullets are a 155 lswc and a 160 lrn powder coated over 4.6 grains of HP 38. The 155 is right at 1,000 fps. I have not chronoed the 160 yet. I load around 1.125"-1.130". The gun will dictate the length. My brother's XD 40 will not take a round quite as long as mine will.

Load as long as possible and do a ladder test and work up your load. Most of the time, I make the load just strong enough to work the slide when I shoot weak hand only. The 155/4.6 load is a couple tenths hotter because it seemed to be a tad more accurate/consistent.

I have run up to 200 grain copper plated bullets in the XD 40. I don't recall if that was with 231 or a different powder. Hp 38 is a bit cheaper than 231 and more available, in the past, although they are the same. 231/hp38 is my go to pistol powder in a number of cartridges. It works for light rifle loads as well. Lately I have been using red dot for other cartridges, and it is similar to hp38. I have not heard of any issues with hp38. I have loaded it under 230-250 grain bullets for 44 mag and 45 colt, but only for light loads. If I want a hotter load, I will go to a slower powder and use the starting load. Like others said, stay away from the top end loads for any powder if possible and load long, for safety. I am not afraid to load shorter if the bullet profile requires it, but I keep the load at min and work up. A short COAL and a max load could be risky.

Many people believe HP38 (and 231) to be fast burning powders.. I discovered recently that it is actually in the medium burn rate range similar to Unique.. So HP38 is actually not as fast as say... Bullseye, Solo 1000, or Clays.. and less likely to kaboom if you are careful and load according to loading data.

Shotgun powder is pistol powder, really. And vise versa. Usually the powder bottles state shotgun and pistol on the label. Shotguns just happen to work with faster pistol type powders.
