Need help with 9mm load!


September 23, 2008, 02:37 PM
Ok, this is my first post. I have been lurking for a while and am impressed with the no nonsense, very informative info, even a new guy like me can get.
I have been loading shotgun shells for many(15) years and think I have got that down pretty good. I have, in the past loaded .380 and 9mm pistol for plinking on a couple of Dillon (450 and 550) presses and I just received all the goodies to start reloading .45acp.
Now, to my problem. I was given a bunch of reloading STUFF from a friend wich included several boxes of Remington 38 caliber 115 grn. .355 dia. jacketed hollow points. Thought that would be good to use for the 9mm.
Problem is the loaded shell will not load and lock in my 9mm. The case is proud and the slide will not fully close. I have to bring the col down to 1.053 before it fits in the barrel. All my other loads (115 fmj) work fine around 1.135.
What am I missing?
Is this not the right bullet?
Mixed cases
Winn sp primer
4.5grn 700X

Thanks in advance for your help

Remington 38 caliber 115 grn. .355 dia. jacketed hollow points.Assuming these are not .38 cal. revolver bullets, since you say they are .355", and that makes them 9mm bullets.

SO, bullet shape & rifling leade in a specific gun dictates seating depth.

If you take the barrel out of the gun and use it for a guage, they need to drop in the chamber flush with the barrel hood of thier own weight.

Whatever seating depth that is, is the seating depth you need to use with that bullet design, in that gun.

Thanks rc
I did take the barrel out and worked down to 1.053 before it fit right.
Is this ok to shoot? I hear so much about short col.
Thanks again

Short OAL will increase chamber pressure if it is quite a bunch, but a few thousands won't raise the pressure that much and won't be a problem unless you are loading at maximum powder charge then it becomes critical...

Deliberately loaded 50 rounds of 185 grain plated flat point Rainier .45 ACP with a light load of WSF and set the first 25 at 1.175 OAL and the second 25 at 1.250. The diference in fps was a grand 75 fps on average. The longer (1.250) rounds failed to completely cycle my Colt Series 80 about 5 times (stove piped the cases)...

What model is the pistol? How far a loaded round seats into a barrel can be a million different ways and still be A-OK. After some practice, you will gain the ability to feel/hear the right sound when you drop a round into the barrel with the bullet not touching the leade, and the mouth fully headspaced properly.

FWIW, CZ pistols have notoriously "short" chambers/short leades and many bullets, especially cast TC styles will require what seems a very short OAL. Here are my two nines w/o barrel hoods (M9 and P1), and both rounds are seated properly and fully.

Thanks. I have a Daewoo DP51. My bullet looks about like that, but in my gun that is not right. At least not consistant with factory rounds.
Also the bullet tends to stick in the barrel even when dropping it in.

Assuming that you've belled the case mouths to seat bullets have you given the loaded rounds a slight taper crimp to remove the belling? A loaded round gauge (Dillon and others sell them) is helpful for loading for autoloaders. A short chamber or throat could also cause these problems.

September 23, 2008, 03:58 PM
Yes to crimp.
It fits my dillon case gauge fine, just not my gun.

Thanks again. Need all the help I can get.

Hope I don't self-elect as the stupidest guy here, but...

You definitely checked the bullets yourself with a caliper to make sure they're not .357 diameter 38-cal bullets, which most are? I know it's two thousandths and I'd honestly expect it to chamber in my CZ 9mm anyhow since that's pretty picky, but too fat a bullet would explain the problems you're having.
Otherwise it's simply a matter of nose profile, certain ones don't work in certain pistols at all, while others have to be seated a certain depth to work. Have a buddy whose P-345 simply will NOT cycle TC-nosed bullets until they're seated so deep it'd make your backside pucker in fear.

Personally my guess is they're .357 diamater slugs.

4.5 Grs 700X is not going to be a problem with those 115 Gr bullets even at a short O.A.L. (assuming their .355)

I shoot 4.7 Grs 700X with Hornady 115 Gr FMJ encapsulated bullets and Ranier 115 Gr Plated RN bullets @ 1.130 to 1.135 O.A.L. with absolutely no pressure signs.

Gives around 1100 FPS in a 3" XD barrel, around 1150 FPS in a 4 1/2" TX 75 barrel, and around 1300 FPS from a 16" AR barrel.

I tried 4.5 Grs 700X with a Berry's 124 Gr HP @ 1.030 O.A.L. the other day and it was a mouse fart load that needed more powder.

Thanks depoloni, But I checked that first.It is .355. Box does says 38 caliber .355 thats what has got me confused.
Thanks Walkalong.

I alluded to that in the 2nd. post.

They can't be .38 and .355" at the same time.

But Remington doesn't make a 115 grain .357" JHP revolver bullet, so I didn't press the issue too far.

But I agree he should measure the bullets and make sure they are .355".

Bullets in a free box of "STUFF" don't always come in the right boxes!


September 23, 2008, 05:36 PM
Sorry guys.
The box says 38 Caliber 115 grain .355 dia. jacketed hollow pt.
It has what i'm guessing to be a part # B23564. They do measure with dial caliper .355.
BTW These boxes were sealed from factory.

I would love a .357" 115 grain JHP for my "generously" dimensioned barrels.

September 23, 2008, 09:13 PM
I hope I added a PIC of the box.

September 23, 2008, 09:15 PM
I will go to test area. Sorry.

Very interesting, very interesting indeed. Nice score!

I'll play along with it's modern day brother, atop my ancient DUPONT loading guide. These Rem 115 JHP's are nice, and the one shown was stripped from one of my SD/HD mags backed by 7 grains of HS-6. Gets about 1200 fps, and seems accurate

September 24, 2008, 04:07 PM
Hehehe... see? I warned us!

No idea what that could be. I saw you said they were .355 and RC restated the concept, but didn't see specifically that you literally checked yourself. I'm slow sometimes. That's the damndest thing though, can't figure why they wouldn't chamber. The modern Rem 115's work "jest fine" for me.

September 24, 2008, 10:25 PM
UPDATE: Just wanted to let all of you know the bullets shoot fine at 1.053. Low recoil, knocked the plates down hard.
Will repost when I get the old PACT out.
Thank you gentlemen for all your knowledge and help.
