Reloading 9mm with SJHP question

[Julian537]

I need to know if these can be reloaded in a semi automatic pistol?
I read somewhere that these semi jacketed hollow points are not for use in semi autos. They are 115gr bullets. They are longer than my lead round nose bullets. To get them into the rounds I am making and an OAL of 1.145.

They will probably compress the powder. (is this a bad thing?)

4.7 gr of Unique fills the case about three fourths of the way.

First Julian; Are you sure those bullets weigh 115 grains? Sure look like Remington ".38" caliber SJHP bullets of at least 140 grains and a diameter of .357". Now, I will say I have loaded 125 grain Hornady XTP-HP bullets sized .357" in my Beretta pistol that has a groove diameter of .3572". Works very well despite the bullets configuration and is super accurate.

Weigh those puppies.

 

[Julian537]

They are .355-.356. in diameter.
My scale only goes up to 110 grains..... argh.

I got 1500 of these at a garage sale, for a good price. They are in ziplock bags. I have 115gr Jhp written on the bags. That is all I know. I agree that they look like Remingtons. I looked all over the net, and the remingtons, were the only ones I could find that look even remotely like these.

Julian -
In reloading, knowledge is safety. Your safety.

Set those bullets back in a corner and save them for a time when you have a better scale and a micrometer. Otherwise you are trusting your safety to what someone wrote on a bag 15 (?) years ago. That's no way to reload, brother.

Think about it. They won't melt or disappear if you wait a year yourself.

Those look like 158's to me.

RFwobbly,

Thank you for the words of Safety. That is the reason I am posting this and learning. I will not reload these until I know for sure what they are. They did mic. at .355-5 to .356. I will get a scale that weighs more before I load these into anything. They are longer than my hard cast lead bullets of 125gr.

Thanks again.

Julian537, you have the right response to the advice given. Most of these guys here that have been doing it right for so many years will have your best interest in mind, safety!
I bought a bag of 7mm rem. mag. brass at a gun show a couple of years ago and all of them were primed, and supposed to have been resized and trimmed to. But because I don't ever use anything based on someone elses verbal claim I tossed the primers and resized all of them, just because I won;t take unnecessary risks. As it turned out, the brass was not trimmed, and not all the brass had been resized.

Bolt Cutters.

They look like 158's, and if so, are unsuitable for 9MM.

I shot some Powerbond 125 Gr HP .38 Spl/.357 Mag bullets in 9MM cases this weekend just to see how they would do. They shot just fine. Although some tight chambers may have trouble with the bigger bullet diameter, they chambered easily in my nines, including my tight chambered EMP.

Bolt Cutters.

Good call. I was wondering last night how I could cut one of these in half and measure the two halves. I knew it might be a struggle with a knife, but I did not think of bolts cutters. I have a set of them.

I tried some semi jacketed hollowpoint bullets in a 38 Super. The lead nose was so soft that it deformed badly and jammed on the feed ramp. If I only load one in the mag, that would feed, but if I loaded five, they would deform the nose and jam. I guess the extra spring pressure from the mag with 5 slowed the feeding just enough to jam. Normal lead bullets shapes, round nose, truncated, and SWCs all feed fine from the same mags, but the exposed lead on my semi jacketed bullets was way soft (hollowpoints).

Where are you located? I'll gladly weigh them for you. If your close to another member, I'm sure they will do the same .

I cut one in half and measured both halves. 159 grains.
It looks like these will not work in my 9mm ever.

To answer the original question, back before the mid-80s, it was common to use jacketed .357" bullets in 9x19 as .355" bullets were not readily available at the store.
I have shot lots of semi-jacketed remington .38 bullets out of various 9x19s and they performed very well.
You simply start, as always, with the starting load for that weight bullet and work your way up.
Anything in a plastic bag must be checked to verify.
