A little problem with my 9mm loads in my XD9.

Hi, all. I've been reloading for most of this year, both 9mm and .45acp. The loads are now consistent and accurate. Unfortunately, my 9's cause an occasional problem with my XD9. About once or twice out of 100 rounds fired, the slide fails to go into battery. I don't mean the kind where a gentle push on the slide seats it. I mean where I have to "thwack" the rear of the slide on a hard object (pointing downrange, of course!). Thus, I really don't think it's a recoil spring issue. If I remove that round before whacking it into place, and put it into another mag (or even the same mag), it goes without a hitch. My 9mm rounds are loaded to 1.165", with a 0.344" crimp (same as WWB, which works fine). I'm using 124gr. fmj over 6.0gr. of Power Pistol. The rounds drop into the chamber. Any thoughts?:confused:

Try using a Lee Factory Crimp Die, the built in carbide sizing ring gives that extra resize to ensure positive feeding. Sounds like you have a tight chamber. Just my thought.

Take the barrel out of the gun and use it to "chamber-check" all your ammo when you load it.

When you do find one that won't fit, you will be able to find the problem and correct it.

Everyone has a great idea...Me? I only have one. I had the same problem with my Kimber using AA #7. Even at higher pressures it would leave granuals in the chamber as the case was extracted. The in coming fresh round would jam on the unburned granuals and not go to battery. I don't know what powder you are using, but you might try W-231 or WSF or any other clean burning powder. My Kimber UCC II does a fine job with WSF...

This works for any round in any chamber. If you've got an issue, the first thing to do is test fit them all.

Some Bullseye shooters will take every round and test fit before an important match. No matter that they already visually inspected every round.

Of those that did fail to allow the slide to go to full battery, did you take notice of the differences of the brass/loaded cartridge? Or just shove the slide home and make it fire?

Bushmaster, been using AA#7 for a few years in my CZ pistols, hadn't noticed that with any Accurate powder, will look more carefully. Never a jam due to that - only bad COAL...oops.

Armeredman...I took a measurment of my Kimber chamber and compared it with my Colt series 80 with a Wilson S/S barrel and bushing. The Kimber seems to have a tighter chamber. AA #7 works quite well in the Colt. Of course the Colt has a 5" barrel compared with the Kimber's 3". Which may make a difference.

It was just a thought that ChuckB could look at...

He could try gauging (http://www.midwayusa.com/eproductpage.exe/showproduct?saleitemid=888465) all his sized brass before loading it. There is some real junk lying around at the range that will not size down properly, even with an "undersized" (http://egw-guns.com/store/index.php?main_page=product_info&cPath=40&products_id=40&zenid=8f1a2afb3145e989536c3b1b8cc2221f) die from EGW.

It can jam up a tight chamber gun in a heartbeat. Also, XD's are known for short leades. he may just need to seat his bullets a tad deeper. Easy to check with the barrel out.

Yup- that's what I use. My mind is still open to suggestions. The ones posted so far are great.
