9mm reloading help

[hvychev77]

i just started reloading 9mm recently. i am loading hornady xtp jhp 90 grains over top of 5.8 grains of W231. I actually called hornady a while back for a recipe for 9mm, and they were very helpful. However, i am loading to .2 grains past the max, which is 5.6 grains of W231, and when the last round is fired from the magazine, the slide does not stay back. i don't want to keep making the load hotter just for safety reasons of course, and i'm not trying to beat up my glock26. I am loading on this recipe 5.8 grains of W231, c.o.l. @ 1.070. Here's the info. hornady gave me....

90g Hornady xtp jhp
W231 4.7-5.6
c.o.l. 1.070

Any suggestions? or is this normal for the slide to close after last round? thanks guys....hvychev77

does it do it on all your mags?

when i shoot winchester white box, they all function fine with all mags. It's just my reloads that do this.......

Isn't that 90 gr for the 380? Is that the right bullet for the cartridge (assuming you mean 9X19)

^^^^ This. 90gr's are for 380 not 9mm. Use 115, 124 or 147 9mm bullets.

Hmm Guess you can use them. Never heard of anybody doing it though.

You may have found a bad match; i.e. this bullet/powder doesn't work in your gun. It happens. Sometimes it's weight, other times it may have more to do with the shape or the exterior surface/jacket. Your options are simple: try a different powder, get heavier bullets.

i know these bullets are for 9mm. it's on the side of the box, plus i called hornady as well and he gave me some good info on the recipe. i was just concerned about going over the maximum recommended charge for this particular recipe, or if others had experienced this? is it normal to go past the maximum charge amount? thanks guys.....hvychev77

I would stick with the more common weights for the 9MM Luger, like 115, 124, or even 147. I think that may have something to do with your slide issue, but couldn't explain the technical aspects. What is the gun? The over-max loading may also have something to do with that, not that it's too much for the gun, but with semi-autos, it's all about timing. Give the heavier bullet a go and see if that helps.

I have shot the old Remington 88 Gr JHP in 9MM and it cycled guns fine. I was using a more medium burn rate powder in AA #5. Perhaps that weight bullet won't lock the Glock back reliably at that recoil/velocity level. The only thing to do is to try heavier charges of a slower burning powder (following the appropriate data) and see what happens.

 

[hvychev77]

right on guys. i think i'll just load this box up, at the recommended charge, and then just order some heavier bullets. i just wanted to make sure i wasn't doing something wrong since i'm a newbie here. plus, i only have the 1 powder to load with too as of now. i'll just deal with the slide not staying back for these rounds, it shouldn't take too long to shoot 'em up......thanks again for the info.

No, it's not normal or recommended to exceed the Max powder charge. You have reason to be concerned. I highly recommend you stay within the published limits.

i only have the 1 powder to load with too as of now.

There's nothing at all wrong with using W231 in the 9mm. A 90gr bullet however is a little unusual. When I load for the 9mm I like using a 124gr bullet although 115gr bullets are cheaper and will also work well.

Here's my question... Are you crimping these rounds? If you're not I would suggest you do so. If you are I would suggest making sure you are using enough crimp. There is something very strange going on when you are above the Max recommended charge for that recipe and you aren't developing enough pressure to push the slide all the way to the rear.

One thing though, your charge of 5.8gr is not above the Max charge listed in the Hodgdon load data and they are using a much deeper seat but with a Speer Gold Dot bullet. Here is the link for the Hodgdon Load Data Site. It's a very useful site with load data for all Hodgdon, IMR and Winchester powders.

i am crimping my bullet, and thanks for asking. i did see the info. on the hodgon website last night. i had been using the data i got from hornady when i called them. i think hodgon's max charge of W231 is 5.8 grains, with a col of 1.010. I had been setting my col @ 1.070, not sure how much difference that makes as far as the slide not staying back. i know it'll create more pressure though........thanks, hvychev77
