9mm reloading

[GReilly]

I bought Berry's 124 gr. hollow base round nose thick plate bullets to reload.
I'm using Bullseye to reload I need to know how much powder to use for the right load? Also is it general for 124 bullets to use the same amount powder if you are using hollow points or FMJ?
Thank you for any help!!

Get Thee To a gun store and BUY AT LEAST TWO RELOADING MANUALS and they have all the info you could ever ask for. Sorry about the caps but this is a safety issue and should not be taken lightly.

What Xfyrfiter said.....

You can also post in the "hand loading and reloading" section of the forum, but you're going to get pretty much the same answer.

I bought a Lyman T-Mag press and the 49th reloading edition came with it,I know they did different tests on different grain bullets but I'm not sure if 124 grain FMJ and a 124 hollow base bullet would take the same load information when using Bullseye powder. Does anybody know?

Bullet shape doesn't matter other than for the OAL. Jacket material (or lack thereof) does in terms of pressure. You need to confirm if you should be using jacked bullet data or lead for those particular plated bullets.

I always use at least 2 sources, preferably 3 when developing a new load as sometimes the starting load in one manual can be at or near the listed max in another for the exact same bullet/powder. The 3rd source is like a tie breaker. Can go online to the powder manf. or the bullet manf. to get a 3rd source for free a lot of times.

Edit: From Berry's website

We recommend using hard cast load data or start with mid-range jacketed data. Make sure data is below 1250fps unless you are using a Thick-Plated bullet that we list a higher max velocity for like the 9mm 124gr HBRN-TP that can be shot to 1500fps in open class guns like a .38 Super. Keep in mind that since our plated bullet has the same pressure curve as a hard cast bullet, the published cast data will be very close to what you will get with our plated bullets. If you use Jacketed data with our plated bullets you can get from 5% - 8% increase in velocity using that data.

Berry's 124 gr. hollow base round nose thick plate bullets to reload ... I'm using Bullseye

When you can't find plated load data for Berry's plated bullets, they suggest we use low to mid range jacketed load data. I have used lead load data with Berry's regular plated bullets and experienced good results. With thicker plated HBRN-TP bullets, I have used low to high range jacketed load data with good results.

Current Alliant load data lists 4.4 gr max charge for 124 gr Gold Dot plated HP at 1.120" and Lyman #49 lists 3.4/4.2 gr for start/max charges for 120 gr lead RN at 1.065" OAL/COL - http://www.alliantpowder.com/reload...owderlist.aspx&type=1&powderid=1&cartridge=23

I tested Berry's 124 gr HBRN-TP using 1.135" and 3.6-3.8 gr Bullseye. Both powder charges reliably cycled the Glock slide and 3.8 gr produced more accurate shot groups. I would use 3.6 gr as start charge and make 10 rounds at 3.6/3.8/4.0/4.2 gr and see which loads produce greater accuracy. You can stop the range test anytime the load reliably cycles the slide and produces acceptable accuracy. 3.8 gr may work for your pistol and 4.0 gr load may produce greater accuracy.

Also is it general for 124 bullets to use the same amount powder if you are using hollow points or FMJ?

No, often it depends on the bullet seating depth. In general, since the hollow cavity in the HP bullet nose increases the length of bullet base, HP bullet base will get seated deeper in the case neck than same weight FMJ/RN bullet base and will use less powder charge. BTW, 2004 Alliant load data lists 4.9 gr Bullseye as max powder charge for 125 gr FMJ at 1.150" while Lyman #49 lists 4.5 gr as max charge for 125 gr JHP at 1.075" - http://www.thehighroad.org/attachment.php?attachmentid=182147&d=1364769070

Since Berry's hollow base also increases the bullet base, I used more conservative load data for my testing and decreased the powder charges by .2 gr (I used 3.6-3.8 instead of 3.8-4.0 gr). If you cannot find load data for the same reloading components and OAL/COL that works with your pistol/barrel, it's a good idea to start low as you can always work up.

The Berry's 124gr HBRN bullet is a "Thick Plated Bullet Rated to 1500 FPS for 38 Super Loads". This statement is available on the Berry's site.

Jacketted 124gr RN data works best for this bullet. I only load it to 1170'/sec to use as a simulator for my S.D. Gold Dot loads.

An excellent bullet, can be loaded long in any 9mm pistol, bevelled base seats easily.

As already said, get at least 2 good/current manuals and read them cover to cover 3X. The start slow on a single stage press and ask a lot of questions.

9mm can be difficult for beginners. Welcome to the best place on the Internet to learn/practice reloading.

The Berry's 124gr HBRN bullet is a "Thick Plated Bullet Rated to 1500 FPS for 38 Super Loads".

And it works well for that. You cannot hurt this bullet at 9MM pressure or velocity. When I tried it in 9MM I loaded it at 1.140 to 1.145 and ran it around 1075ish FPS. I am saving them for .38 Super now that they proved themselves in it at 1300+ FPS.
