Hi all
I just loaded 400 .45 ACP and about 80 were too fat for the case guage checker. I have a Dillon 650 and the resizer die is as low as it can go. The brass is mixed but does not seem to matter as to name on brass. Some wont even go 2/3rds into the checker.

I hear glocked brass will expand due to unsupported chamber. Not sure if my brass was through a Glcok but should not the resizer die fix this?

What can I do to prevent this with the setup I am using?

Cheers
 
Thanks for replies fellas

The rounds do not fit into the barrel. Most stop with about 2 mm too far out. Some can be jammed into barrel but I am sure this will lead to a FTF in a course of fire.

I am using .451 Aim CMJ projectiles

So the Lee die just fits into where my Dillon crimper die sits? What does it do differently?

Cheers
 
It resizes the round to be exactly the same as factory and the crimp is about the best in the industry.

I had the same problem when I first started loading my 10mm's in 1988 Dlask Arms told me to get the lee die...
 
The Lee FCD replaces the Dillon crimp die. It is essentially two dies in one. It is a tungsten carbide sizing die. It's sizing ring will make sure your completed round is not too fat for the chamber. Because you are using it last, the radius at the opening of the die and taper leading in to the die can be smaller and tighter. It sizes the case down further than the standard sizing die. It also crimps the case.

With the plated AIM bullets, you want a very light crimp. Essentially just remove the belling and a tiny bit more.
 
X1 for the Lee FCD.My STI has a very tight chamber,and if Im using lead,I will get an occasional failure to chamber.This doesnt seem such a problem with FMJ bullets as their diameter is a bit less than lead bullets.The Lee die taper crimps the case,and there is a carbide ring at the bottom of the die that irons out any bulges in the case.Ive found that its made a big difference in the reliability of my reloads in my 45.Some will say that accuracy is affected,but off the bench(at least for me),I cant see much difference.I think that Lee also make a "bulge buster" die for "glocked" brass,check their site.Lee also makes the 'U" die(available thru EGW)which sizes slightly tighter and lower down the case than a regular die,getting rid of any bulges lower down.I use one for my 38 super and I (think) that they make a 45 one as well.Glocked brass has a characteristic half moon bulge at the web of the case

Your round failing to chamber fully in your barrel,suggest that your round is loaded a bit long and is hitting the rifling which is stopping it chambering fully.Perhaps seat the bullet a bit deeper and see if this helps

Finally,some of the case checkers seem really tight.I have a EGW checker for my 38 super that rejects a good 30% of my reloads,but when I use my barrel as a checker ,they all pass and fire just fine.
 
OK, just chamber checked rounds. 60 out of 80 fit with some snugness. Should function.
About 10 could be fit into barrel and had to be removed with wood squib rod. Other 10 need to be recycled. Weird how even ones that fit OK were still sticking out of guage about 2 - 4 mm.

(Lesson learned - check before posting :))
 
I am loading to 1.22 OAL. This seemed to work well with ones I chronoed yesterday, I think the length is OK, at least the ones that fit into barrel.
 
+1 for the Lee FCD. And it that doesn't do the trick, you should maybe take a look at this:

OK so I purchased and installed the Lee fCD and then ran through the 80 rounds that were too fat. After going through the Lee die, all but two were able to fit into the case gauge. I am sold! Made another 100 rnds and all fit into gauge. I will definitely pick one up in 9mm.

Thanks for help on issue guys. Gun nutz came through again!

Cheers
