So those of you with 11gr of bluedot, where you seat your bullet at? Standard 1.25"? or longer?

I just loaded 10.3gr of bluedot with XTP, and seems like there isn't much room left before it becomes compressed load?

Do they make mag extension for 10mm like they do with 45?

I have been contemplating about making some load using Bluedot.
I have crap load of 180gr XTP bullets, so I'm gonna use that.

According to my Lyman 49th edition book, its recommended max load for Bluedot with 180gr jhp is 10.3gr @around 1133fps.

But according to Alliant Powder's website, they list load which is 11gr of BlueDot @ around 1295fps.
SO which is safe limit? Is this mean that 10.3gr on Lyman is like lower end of known limit(just be in safe ide), where as manufacture list more realistic upper limit?
I have done 10gr with 180gr, which worked without any issues. So I'm thinking may be I'll try by starting at 10.5gr and see?
Now, I'm going to be shooting these out of my LW barreled Glock G20, and my Colt DE.

I have shot a few hundred 155 XTPs using Bluedot. Lots of muzzle  blast compared to other powders I have tried.

  Blue Dot is vocal, without question. It does seem to like working with XTPs, though.

No doubt! My only issue with blue dot is that its hard to come by around here

Ramped, cone barrel. Ramp is std. But unusual one. Only source is RIA.

Yes, Its reverse pluged heavy barrel with Para/Clark based feed ramp called Para/Clark/Lissner.
Its radiused corner unlike standard Para/Clark, and frame is cut accommodate it
And you can also get a barrel from Infiniti(for like $250!) in this configuration(Heavy barrel, P/C/L ramp in 10mm).
I was told that standard Para/Clark will work with frame cut for P/C/L feed ramp

I'd get in on it if I can do like 500rounds...

thanks. I wanted CCI300, but no one around here has them, and I found those Winchester Lg pistol primer for $34.99/1000.

Is there any? as far as performance goes?
Can I use them in place of CCI 300?

In the pictures you posted is is clearly evident, why seating and crimping should be done in separate steps.  This one in particular shows the bullet is not completely seated to proper depth, when the crimp was being applied.  The casing started to close up, the casing grabbed the bullet's jacket material and then the casing started to buckle as a result.  While it is possible to make the cartridge in one step, they may not even show things that are happening, grab the bullet and see if it will turn in the casing.  Push (against a strong surface) / pull the bullet looking and feeling and even measure for any movements. The slightest discrepancies can cause you feeding reliability issues.



By seating without crimp being applied you get straighter bullet seating, better casing to bullet tension, then when you apply the closing crimp, it tends to lock the bullet in place better, as the case mouth closes toward the bullet that isn't moving.  Sometimes when you check by pulling cartridges apart, you can see a slight crimp ring on the bullet's surface, this is not a bad thing or too much crimp, because the crimp pushed straight inward to lock it in place.

Ya you pretty much hit the nail in the head.
My friend adjusted the dies. It took him several tries. But I think its running good now.
I loaded another 20 rounds - 10 with 9.3gr blue dot, and another 10 with 9.8gr.
I think it look good.




OAL is 1.255". is that too much?

Well, I loaded up 10 try out rounds.
5 of 8.1gr, and another 5 of 9.0gr(although, it ended up being 8.8gr. I need to work on my powder dropping technics...)
I actually had a issue with not being able to set up my seating dies correctly. And very first 2 rounds I loaded was really bad.
My friend, the reloader had to come over and help me(or more less he did it, and I watched) set up my seating dies.
(something about my taper crimp dies were too low - or screwed in too much, and it was crimping the round before bullet had seated)



So after my friend set up the dies correctly, I made first 5 rounds. He, the reloader felt that the 8.1 was too light. So he adjusted the powder drop and i made another 5 with 9.0gr of Blue dot

OAL was set at 1.255"

It was getting dark. So we just went out to shoot it, just shoot it.
8.1gr IS too light. gun felt like shooting 9mm 1911.
9gr is still not really hot in anyway. Felt like shooting .38Super.

Its a small start. But Im so excited that those 10 rounds functioned.
reloader buddy and I feel that may be I should try somewhere in 9.8gr range next time.

Im gonna do some research and try some more reloading tomorrow.

Oh we didn't chronograph it, or even really aim at anything.
But I bet FPS was low 900 range...

But they all fired, ejected, and loaded the next round

What type of gun, what bullet head/powder/etc ?

The case is mix of Hornady, and Federal Eagle. All fired once.
Gun is RIA 1911 in 10mm with full support(wanted DE for the longest time. And I'll likely get it in future. But I wanted one with full case support).

Recipe for this load.

BlueDot 8.1gr
CCI 300 primer.
Hornady 180gr XTP #40040
OAL 1.250"

According to book, this should give me around 950fps. I know its sort of weaker side of things, but I figured I'd start min suggested starting load. I'll load 5 this. Then slowly increase the charge up to about 9.5gr, and shoot for around 1100fps?
Being that this I first time, I feel like I should start slow...

This is my first time(ever) reloading. So bear with me...

Im attempting to reload 10mm for the first time.
I'm using RCBS 3 dies set on single stage turret press.

and Im having little issue trying to figure out few things.
According to my Lyman 49th edition hand book, SAMMI spec dimension for 10mm is:

Case length:0.992"
Case Mouth:0.423"

My once fired case is uniformly oversized(naturally), and I put 100 empties through resizing die last night(how de-primer "pop"s the spent primer was interesting)
Because its my first time, I measured every single one of resized cases, and none of it matchs the number above.
After resizing, case mouth were 0.416"+.001~.002".
I figured this wouldn't matter, as it will be flared at next station, and once bullet is seated, i'll take the measure again.

But my case length were avg. of 0.986". Its anywhere from smallest of 0.982 to largest of 0.988".
And none came close to 0.992" as my book says.
Is difference of 0.006" something significant that I need to worry about?

Thanks, and sorry for possibly a stupid question

That's funny, as I live in Center County! State College to be exact.
Small world.
Although, 1976 is before I was born...

Yes, I have been reading up many topics in Reloading section.
So much info makes my head spin!

Hi guys. Been lurking for a while, and finally got around to join up.

I got hooked on 10mm recently when gunshop talked me in to buying RIA 10mm Tac.
I now kicking my own butt for passing on buying Colt Delta Elite or Kimber eclipse 10mm in the past.

Anyway, I've joined mainly to get more info on reloading 10mm, as there are pretty much no 10mm ammo around here, unless you pay up to bang hole, or order them online(and still pretty expensive and on the somewhat weaker side of things.

I'm setting up my reloading station right now - I got press, powder measure, and manual. I'm hoping to pick up everything else that I need, and start reloading by the end of month.

It's been way too long since I shot my 10mm(March, May be? There were still snow on ground last time I had 10mm ammo to shoot...

Edit - oops, looks like I posted on wrong place. I didn't see the post where you supposed to do introduction...
