just started making loads for 9 mm and am having some problems with them
at first i made 5 to make sure they would feed went out and shot them they all stovepiped then i compared them to factory loads that i had and i had loaded thes bullets to max overall lengthso the next set went in to match factory ammo length i took them out and tried them and they fed fine so i loaded up 150 of them took them out today and only 1 or 2 of them fed properly and didnt stovepipe

the gun is a springfield xd-9 tactical

the load taken directly out of speer # 13
speer 125 gr lead bulk bullets 500pk
4.1 g win 231 powder
cci small pistol primer


the only diff between the test frired rounds and the ones i did today is i had a laser on the gun for the test rounds could the weight of the laser be allowing more recoil to go into working the action instead of moving the frame
like how a limp wristed shooter willhave feed problems
 
Someone might have a bit more insight than I into the question, but I can tell you the only times I've ever stovepiped was when I was first starting to reload, I would start with the minimum charge, which didn't have enough power to fully eject the case, causing a stovepipe.
 
seems like it might be a low charge weight.
Sierra reloading software states this:
231
3.9
4.2
4.5
4.8
5.1

You are loading them way at the bottom end ( I think you are in the 900 fps range). Its rather slow and probably not producing enough energy to cycle the slide.

That is usually the problem.
 
so it sounds like i am going to have to pull them or get a lighter spring i was hesatent to load higher as that is the max loading that speer shows with that powder bullet combination
 
The Hodgdon site shows for 231 powder & 125 grn lead bullet, a minimum powder charger of 3.9 & a maximum of 4.4 grains of 231.

I would not ( IMO ) suggest a lighter spring as long as the gun has a factory one. I would just bump up the powder charge within safe limits, make sure that the overall length is correct & your problems should go away.
 
Your load is exactly what I use for IDPA/IPSC. PF is around 130. I suspect it is your recoil spring. Gun is probably sprung for heavier loads up to +P. Try a lighter recoil spring. Changing recoil springs to lighter ones is quite common amongnst competitive shooters for a variety of reasons. My STI Trojan would not lock to slide lock after the last round until I went to a 11# spring. Gun was set up for full power factory loads using jacketed bullets.

Incidently that load is extremely accurate in all my 9MM guns. It is well within minimum loadings.

Take Care

I noticed on the hodgdon site that bullet type can play a factor.

125gr Sierra FMJ
231 powder
min 4.4grns max 4.8grns

Bullet type does play a factor. A very big factor is lead bullets as compared to copper jacket. FMJ is copper jacketed .
