130gr JHP HST load

Midway is having a sale on some blemished bullets. I bought 600 130gr HST bullets. These are the bullets used for 38sp. HST rounds. This bullet seats
flush with the end of the case like a wad cutter. I'm looking for load data
and/or powder recommendations. BTW the cost was only $16.00/100 and free freight it you buy over $50.00
TIA

I don't know the length of the bullet, so I hesitate to recommend anything, though it will probably turn out that something like 231/HP38 or possibly even Power Pistol will work. Too many unknowns, otherwise.

I was having a senior moment.

Thanks for the info. I had it in my mind I needed to load these bullets just like the HST 38spl ammo. The factory bullets are loaded flush with the end of the case. Loading them like that would be the same as making a bomb!
The actual bullet measures 0.610 BTW and they have a cannelure. I just wasn't thinking at all. Sorry to waste your time.

CAUTION: The following post includes load data generated by calculation in QuickLOAD (QL) or Gordon Reloading Tool (GRT) software and is based on particular powder lots, the assumption the primer is as mild as possible, and assumptions about component, chamber and gun geometry that may not correspond well to what you have. Such data should be approached by working up from published starting loads. USE THIS DATA AT YOUR OWN RISK. Neither the writer, The Firing Line, nor the staff of TFL, nor QL's author or distributor nor GRT's author assumes any liability for any damage or injury resulting from the use of this information or information derived from it.

Even loaded flush, they are no worse than a wadcutter and are in that same length range. QuickLOAD thinks Power Pistol is one of the best choices, giving loads a little over 3.5 grains for just under 1000 fps from a 6" barrel. This does not take barrel/cylinder gap loss into consideration.

Thank a lot! I will think a bit more. I can check the vel and see if I'm on the correct track
Again, thanks

Unfortunately I have not loaded up any for 38 special yet. But if you start using them in 357magnum I did work some up for that.

I bought some from midway too. I have a hot 158 gr SWC load that i use. 6.5 grains of HS-6 and a magnum primer in 38 special. I decided with that lighter bullet but being seated deeper in the case it’s probably about the same in terms of pressure. I loaded some of these 130 gr jacketed wad cutters with 6.5 gr of HS-6 and a mag primer in a 38 special case. And will shoot them from a stout 357 mag gun and run them through the chrono. If velocities exceed 1000 fps I’ll back the charge down. If not, I’ll run that load.

This is getting interesting

Radny97, I hope you post the info. I believe the expansion of factory from
https://www.luckygunner.com/labs/rev...cs-test/#38spl
2" barrel gave 13.0" penetration and 824fps and .73" expansion
4" barrel gave 14.1" " " " " 854fps and .71 expansion
I'm going to guess that faster vel. may hurt expansion? Just a guess
but maybe the bullets start shedding pedals if you push them too fast?
It would seem even at low vel. these bullets leave more than a big welt

I think the greater velocity may actually result in greater expansion and less penetration. I’ll keep you posted on this thread, but it may take some time. I’ve got a few loading projects on the bench right now.

Well i went and tested the 6.5 grains of HS6 load today. It’s too hot. From a four inch barrel i got 1170 fps and barely penetrated three water jugs with violent expansion and jacket separation. Sticky extraction. I’ll try 6.0 grains and run it again. Accuracy was great.
With the level of expansion I’m guessing this will be an excellent bullet once i get it down to 1000 fps from a snubnose.

I think the vel. range is on the lower side to work well

The sweet spot must be below 1000fps. I haven't loaded any yet as my
stuff is at work (so the wife doesn't know) and the heat and humidity right now
I think would effect the ammo,s life span. When I do I will post it.
Thank you for the information!
