9mm 115gr plated recipe

[MoreIsLess]

I have been using 124gr lead and plated for a while now with 3.8 gr Bullseye. I finally decided to try 115 gr xtreme plated. Can someone suggest a recipe using Bullseye (something not to snappy) for 115 gr plated.

I don't wanna sound mean, but why would you trust???
What if they make a mistake? It's your equipment that suffers.

I own 7 manuals plus the 9 mm One Book/One Caliber deal. (not bragging!)
But everyone of them has data for 115gr bullets.
I'll bet you can't find a recent manual w/o data for 115.

If you can't find or afford a manual, look on the powder mfg's websites.
They offer data for free.

Please stay safe my friends.

I have Lymans 49th and it does not have an entry for 9mm 115gr lead, only FMJ. Alliants website has 115 gr FMJ | 115 gr JHP | 115 gr Speer GDHP and that is all they have for 115gr

Lyman #49 does have 120 grain lead data using Bullseye in two different bullet shapes.

Use that data for the 115, except for the OAL, which is different in every bullet design.

You can't get in trouble with 120 grain data using a 115.

BUt you will have to figure out your own OAL / seating depth which has to be determined with the bullet design you are using anyway.

Current Alliant load data lists 4.7 gr max but that's for Speer Gold Dot HP bullet that's different bullet type with different nose shape for different bullet seating depth - http://www.alliantpowder.com/reload...owderlist.aspx&type=1&powderid=1&cartridge=23

2004 Alliant load data lists 5.0 gr max for 115 gr FMJ but that's for a jacketed bullet - http://www.thehighroad.org/attachment.php?attachmentid=182147&d=1364769070

I would follow rcmodel's recommendation referencing Lyman #49's lead load data for heavier 120 gr bullet with 4.2 gr max. I would use 3.8 gr Bullseye as start charge for 115 gr plated RN and test 4.0/4.1/4.2/4.3/4.4 gr. I use 1.135" OAL with 115 gr RN bullets and that length works in various pistols I use. If your working OAL is longer at 1.150"-1.160", I would start at 4.0 gr and test 4.2/4.3/4.4/4.5/4.6 gr and see which produced best accuracy.

9mm with smaller case volume is more sensitive to small changes in powder charge/bullet seating depth/neck tension variations. With lower powder charges and 115 gr RN with shorter bullet base, I found using shorter 1.135" OAL helped with neck tension to produce more consistent chamber pressure build for more accurate loads.

Bullseye (something not to snappy) for 115 gr plated

Bullseye will produce more snappy recoil as you increase the powder charge. As you conduct your powder work up, once you have reliable slide cycling and spent case extraction/ejection, you can stop the powder work up as soon as you attain desired felt recoil and acceptable accuracy.

RC,
Wouldn't the charge be a bit different than he would need since he's using plated? Or is that one of the data options with plated, using the high end (I presume the high end) of lead data?
