My reloads don't fit into my Bar-Sto Chamber.

[Desert_Rat]

I just put a Bar-Sto barrel in my Glock 22. I noticed that only 1/2 of my reloads fit into the chamber.

All of them drop right into my Glock chamber.

I know that the Bar-Sto is a much tighter chamber than Glock. So I need to get tighter with my reloads.

I'm loading on a 650xl using Hornady Dies in .40
I'm using Bear Creek moly coated 180gr.bullets and mostly just range brass I get after the local pistol matches.
I'm loading 3.2 grains of Titegroup. So I know it's not a too much powder
problem.

I suspect that the problem lies in the brass, but could it be the sizing die?Which die would be considered higher quality for more precise FL sizing?

I've had a Wilson chamber gauge for a while and all of my ammo fits in there, just not the Bar-Sto. Factory ammo fits into the new barrel perfectly and functions flawlessly.

BTW I really like this barrel, it's pretty rad.

excessive throat bulge area unaffected by sizing die maybe?

Might be the shape of the bullet. I've had that problem with a CZ. Take an empty casing, place the bullet your using in the case. Place it in the barrel chamber & push it in by hand till the casing is flush with the chamber of the barrel. Get the cartridge out and see what the OAL is at that point. Then load a few .010 less than what the OAL was originally. See if that helps.

I'd bet the key lies in your crimping. Are you using a separate taper crimp die, or are you using the crimping feature on your seating die? (I believe Hornady seating dies, even in .40, use a roll crimp instead of a taper crimp).

[eaglemike]

Is it a "drop-in" barrel, or a "semi drop-in"? Do you have a headspace gauge? Sometimes the chamber is a little undersize, designed to be finish reamed after the barrel is fit.

What is your overall length? Depending on which 180 you are using, your loads might be a little long for the chamber and throat as supplied.

The amount of powder in the charge is unlikely to affect the fit of your round if you are using anything close to a suggest load.

Try dropping in some empty, resized cases first. If they fit than your sizer die is okay. If they do not you may need to adjust your sizer die, get an undersized sizer die from EGW or you have "Glocked" brass that needs to be fixed. Highly likely you have Glocked brass since you are working with a Glock.

Once the empty cases fit in the chamber, drop in and drop out, then you can move on to adding a bullet to a few and move on from there with bullet type and OAL.

Glock bulge. Very common.

Here is the link for the EGW die that deals with the problem:

If you were closer, you'd be welcome to use my CasePro to roll size your brass. Nothing like 1k pieces of perfect brass in like 20-30 minutes.

We don't really have enough to properly diagnose the issue, but I really doubt this is a "glock bulge" problem. He says 50% of his reloads drop into the new barrel, which indicates that his sizing die is properly sizing in terms of diameter and length (how far down the brass his die is sizing). I could be wrong, but this sure sounds like a crimping problem--the flare isn't being ironed out completely causing a headspacing issue. The 50% success/failure rate could be explained by non-uniformity of brass length.

To the OP, could you be a little more descriptive about your problem? How far do the rounds that DON'T FIT go into the chamber, 25%, 50%, 80%? Does it seem like a diameter problem or length problem--is it fit definitely too tight or does the round just not enter deep enough into the chamber? Pictures would be great, too.

He says 50% of his reloads drop into the new barrel, which indicates that his sizing die is properly sizing in terms of diameter and length (how far down the brass his die is sizing).

I disagree, unless he is using unused brass. If he is using reused brass, then a 50% success rate definitely doesn't rule out the sizing die.

I disagree, unless he is using unused brass. If he is using reused brass, then a 50% success rate definitely doesn't rule out the sizing die.

I agree, it doesn't rule out the sizing die, but it does indicate that the sizing die is working properly. Since he's having, at least, a statistically siginificant number of his brass being sized to within the diameter specs of the chamber, we know that the sizing die's diameter isn't the issue--if it's a diameter issue, it has to be that some of the brass rebounding back towards the pre-sized diameter.

Based on my experience, it would be very rare that 50% of the reused brass is rebounding to beyond the diameter limit of the chamber while the other 50% are "holding" their sizing to within the diameter limit. I guess that's certainly possible, I just don't assign it a very high probability.

That coupled with the fact that he is using Hornady seating dies with a roll crimp (which are notoriously troublesome for semi-auto rounds--google "hornady seating die roll crimp" for countless similar problems being reported on many forums), leads me to believe this is a crimp issue.

BarSto barrels have to be finished reamed to fit your particular load, has nothing to do with fitting a case gage or factory barrel.

[sammy]

I had to get a Lee factory crimp die to get my 9mm reloads to work in my KKM barrel. $15.00 is a cheap enough fix.

[Snoopy47]

I agree, it doesn't rule out the sizing die, but it does indicate that the sizing die is working properly.

I thought it indicated that 50% of the brass was used in a Glock and the other 50% wasn't.

1) Be sure to resize each case as part of the reload process.
2) OAL may be a little too long, shorten it up a touch.
3) Give it a little more crimp
4) Maybe even go as far to rezise the actual bullets after they are complete.

[Desert_Rat]

OK everybody, thanks for looking at this with me.

Here are some pics. Albeit Blackberry phone pics.

The brass is .842"
The OAL is 1.125"
If I drop a freshly sized brass into the chamber, it drops right in there...about 50 of them and all drop right in there.

Starting to think it's in the crimp now. Hornady=Roll crimp...
Disregard the one you can see in the tray lid with the huge dent, it's gone.
Here is one that fits all the way down into the chamber.


Thanks for the link Gryff.

Here is one that does not fit.


Here are the two side by side.
