Hi all again. This may have been answered somewhere but my search fu is kinda weak. I have bought the speer 14 reloading manual and was wondering if their max 10mm is the watered down 10mm. 180 grain 11 grain blue dot? I want to make sure this is right info for what I'm wanting to do. I'm working up from 10 grains

I am not sure if you are asking if the Speer numbers are anemic. If so, then no. 11.0 gr of Blue Dot is pretty warm. Note that it exceeds the Hornady max. I don't know what type of bullet that you are loading. If it is an XTP, they seem to run with higher pressuress and slower speeds than Speer bullets. So it would be best to stick with the Hornady max for an XTP.

If you are looking for a modest pressure and accurate load, an XTP loaded to the low 10s.

The speer 180grains yeah I have noticed that even though 180 seem the same every book I have lists different powder loads for the same blue dot powder. So here's the next question. 180 grain winchester jhp which info do I use? I load 12 gauge but this is first pistol

I would go with Hornady data. Max is 10.7 gr of Blue Dot. No mag primers please. Start charge around 9.0 gr and work up in 0.2 grain increments until you reach excess pressure signs or desired results. Whatever comes first.

Every input will change pressure readings. Hence the varying max loads published. Bullet shape and construction is meaningful. As are the firearm, primer, and brass.

If you are new to loading pistol, it would be extremely advisable to shy away from loading toward max charges. 10- 10.3 gr of Blue Dot is a nice firm load with some margin for error. Excess pressure signs can be subtle (and not-so-subtle). It is the subtle stuff that is hard to decipher. Get a couple thousand loads through your setup before trying to max out. That ia my suggestion.

Have fun and stay safe.

So I should go get the horandy book and junk the speer. Does winchester not do any data for thier components. Everything I have is win cause that's what lgs carries and the gave me enough for 200rds when I bought press and gun

The Speer is a good manual. I would not junk it. The reloading instructions are pretty good. For recipe data, there is a copier quality manual that is called "one Book One Caliber". Pick that up and you will get all of the recipes. I understand that a 2011 version will be out soon that corrects some dangerous errors in the current edition. It is about 8 bucks. You might wait for that. In the Alliant powder sticky thread, someone took a photo of the Hornady recipes. That may be helpful in the meantime.

Also, the powder manufacturers will have load data online. Alliant Powder data will be the same as what is in the Speer manual because they are both part of the ATK company.

Sorry for so many questions but what would the win 180 gr jhp notched be equivelent to loading wise since no book seemed to list them? I have loaded 10 at each level from 9.4 to 10.8 in .2 incriments in new brass just to have a sure idea of pressure signs? Good idea or bad idea?

When in doubt check on line with the manufacturer. Most if not all post reloading info.

Blue Dot works well as listed in the Speer manual's, 11.0 grains is listed as max with the 180 gr. They are not consided watered down in that loading. 10.4 grains is an excellent target loading.

I personally use 10.5 grains of Blue Dot to shove the Hornady 200 XTP's between 1180 - 1200 fps from my S&W1006 5". All the normal cautions apply!

You have done well.

Sweet I figured it was better to have a larger sample to look for pressure signs. Already been blown up once don't want to do it to myself. Tried contacting win for info on bullet but no such intelligent life on other end of phone

Good news I didn't kaboom myself. Worked my way up to 10.8 grains. Checking brass after every 5 rounds. Started minor glock smiles around 10.4 10.6 started fte . only 1 in 10 had that issue. 10.8 was my fav but 2 fte out of 10

Look for left over BDot flakes when there's much powder but not enough time and barrel length to burn them all. Depending on how the wind blows, I got a lot of residue on my forearm once, perfect blackened circles.

Your charges will be fine. You SHOULD be fine with almost any jacketed 180gr bullet up to 11.0gr of Blue Dot (CCI 300 primers, 1.260"). I would take your run out and fire them. Make sure to KEEP THE BRASS SEPARATE!!! Keep the fired brass sorted, so you know which is which. When you get home, measure the maximum brass expansion of each load (maximum diameter of each case). If you're using a stock barrel, you should see a max of about .4335-.434" with the 10.8gr load, and less expansion with the lighter loads. If you're using an aftermarket barrel, this is pointless, and you'll see no difference in any load. Use that hot load as a good maximum expansion point. Later, when working up new loads, you will know you are nearing maximum pressure when you hit that brass expansion figure (whatever yours was). Mine in my G29 is about .4345". If I see that brass expansion figure, I know over-pressure and Glocksmiles are about to happen. That number is not for your gun, your barrel is different.

I've been loading Zero 180gr bullets with 10.7gr of Blue Dot with a 1.250 COAL for a Kimber Eclipse and like it very much. Very close to the feel of a Winchester Silvertip. I've also loaded some with 8.5gr of Power Pistol for an impressive looking and sounding load but the muzzle flash was too distracting for IDPA.

I'm backing down to 10.5 for the majority of my Target loads. I'm only doing the 10.8 grain in new brass for my Washington machine killing loads. something started gougeing the base of my brass real bad and up the side of it. Is this a normal glock phenomenon?

Definately normal. The Glock extractor is pretty violent, especially with 10mm.
