Hello
Just picked up my first Glock pistol and it's chambered in 10mm..
And just joined this forum and am enjoying all the experience posted here.
When reloading a new cartridge for the first time, one should gleen as much info as possible..

I'll starting out with stock barrel and spring and see what happens. I have a 22# spring and rod ordered just in case.

I'll start out with 180 and 200gr XTPs and hard cast bullets.
Looks like about 9.0grs with the 200gr and up to about 9.8grs with 180gr with 800X at a length of 1.26" has been good in everyone's experience. 'Course I will work up to that very carefully.
I'll be working with other powders as well..

The only thing that puzzles me about what I have read is the fascination with magnum primers with 800X..

I've loaded just about every handgun round there is over the years for one reason or another and I have never needed to use magnum primers with anything except H-110/296 which is a must..
Even full charges of 2400 in magnum revolver guns behave quite well with standard primers.

800X, in my experience, is not hard to ignite.. It's just a ***** to work with. It's like pouring Wheaties in a powder measure. Hand weighing is a must.
At 11.0grs, it makes a dandy 110gr JHP plinkin load in .357 Mag L-Frame at 1300fps out of a 4" barrel. And is quite useful in the .40S&W.. all with standard primers.

So.. I was just wondering why mag primers are necessary in the 10mm using 800X?

Thanks much

Not sure where you're getting that info, but 800X and magnum primers is NOT advised. In my experience, this powder can be very unpredictable at higher pressures with some calibers (generally larger, .365 and up), which may be attributed to charge-column diameter and/or depth, and a (relatively) very loose stack. Adding magnum primers increased the pressure and velocity inconsistencies in every larger caliber load I have tried (extensively, albeit years ago). It does work well with smaller calibers, .357 and smaller, and is excellent in .32 Mag and 9mm. I've since dumped 800X from my inventory, as there are several equally effective powder options that actually flow, unlike the corn flakes.

Despite this, there are some handloaders who swear by it. If you're a big 800X fan, give it a shot and judge for yourself.

Thanks.. That confirms my suspicions..

I was just reading through the IMR load data here, starting from page 1, and noticed that a number of 800X loads listed were using CCI350 primers. That's where I got that information. So I was wondering why that was..

Because I enjoy doing research I'll try it in 10mm to see what it does..

Thanks

RDub01, welcome to the 10mm. I echo what DM1906 said about mag primers. I have noticed big differences. I can pushed to faster velocities with standard primers since pressure symptoms have appeared earlier with mag primers. It is a good idea to start at Hodgdon's starting charges. One lot I was working with gave some pretty nasty excessive pressure indications at 9.6 grains. Smiles were evident at 9.1. This was under a 180 XTP. There is some indication of lot-to-lot inconsistencies.

Good luck. Stay safe, and I look forward to your results.

Thanks Tater..
Yes, Been working with 800X for quite a while..
800X is kinda like that dog you never really trust.. Never know when it's gonna bite ya.. There is lot to lot variations for sure..

Anyway really looking forward to load development with this new pistol.. I'll post what I come up with.

Some fresh 800x data in today. Figured I'd give the 10mm a spin after playing around with the 45 Super. This is from a stock Gen4 Glock 20. Brass is 1x Midway (Starline) and CCI LP primers were used. About 80 degrees outside, shooting through a Chrony F1 (tripod mounted and leveled).

180gr XTP, 10.0gr 800x @ 1.260": 1,281 fps (27 fps ES)

200gr XTP, 9.2gr 800x @ 1.260": 1,195 fps (51 fps ES)

220gr SNS, 8.4gr 800x @ 1.270": 1,144 fps (18 fps ES)

Brass looked good all the way around in the stock barrel. The 200gr load wasn't as consistent as I like, but I'm still going to play around with it some more. Thinking of 9.5gr loaded out to 1.270" with either the 200gr XTP or Nosler JHP. The 220gr TCFP hardcast is from SNS casting. It did lead the barrel a little, nothing terrible, but it was noticeable. I'll post up more soon.

You may want to consider coal of 1.2500" to tighten things up...this will increase the pressures slightly by decreasing case capacity and better case to bullet tension. Using a magnum primer may also improve the ignition properties.

Yes there is a little more room for the powder charge (9.4gr of 800X is what Underwood was using) with the 200 XTP.

Thanks Shadow, I usually do run a 1.250" OAL in my 10mm loads, I just figured on trying something a little different. However, I will load some up and try them at 1.250" and see what happens.

A few more:

Gen4 Glock 20 10mm (stock gun, 1x Midway brass, CCI LP primers):

180gr XTP, 10.5gr 800x @ 1.270": 1,315 fps (51 fps ES)
200gr XTP, 9.5gr 800x@ 1.270": 1,227 fps (35 fps ES)
200gr Nosler JHP, 9.5gr 800x @ 1.270": 1,233 fps (26 fps ES)

Not too bad. Next up I'm going to shorten the OAL a little bit to see if it will help out the consistency. I know from past experience that 800x can be very consistent, and while the above isn't terrible, it's not where I want it.

I only went higher than 9.5gr 800x with 200gr XTP one time, but it was with a 200gr WFNGC bullet. I don't recommend going any higher than 9.5gr or so.... after all, you've got plenty of velocity at that charge, anyways.

A safe load would be 9.3gr 800X with 200gr XTP from new brass only.

Have fun, be safe!

Sorry I just saw your reply nickE10mm, yes I feel that 9.5gr is as high as I want to got with an XTP. Yet today I ran 9.7gr of 800x behind a 200gr Beartooth WFNGC, here's my IMR data for today:

Gen4 Glock 20 bone stock

180gr XTP, 10.5gr 800x @ 1.250" (1x Midway, CCI LP): 1,363 fps (15 fps ES)

180gr LaserCast RNFP, 10.5gr 800x @ 1.250"( 1x Midway, CCI LP): 1,384 fps (3 FPS ES!!)

200gr Beartooth WFNGC, 9.7gr 800x @ 1.250" (1x Midway, CCI LP): 1,272 fps (30 fps ES)

Brass look just fine out of the stock barrel. The 200gr BT didn't lead the barrel, but the LaserCast 180gr RNFP did and then some, so I now have some Kroil in the barrel loosening the leading up so when I clean it later tonight it will come out nice and clean.

Hey SD...

Don't bother with Kroil soaking for that severe leading. The tried and true way to clean lead out of a bore (yes, even heavy leading) is with the copper "Chore-Boy" pads... That should read: PURE COPPER (which won't harm your barrel in the slightest), **NOT** copper-coated steel (which will ruin your barrel)

Pick up a pack of Chore-Boy copper pads at the drug store or grocery mart ... Wrap the pad a few turns tightly around a slightly undersized used copper bore brush (I use an old 9mm brush) and cut off the excess with scissors.

Now, cram that copper "lead-cutting-bob" down your bore with your cleaning rod ***DRY, no solvent*** and make about 5-10 passes back and forth they your barrel and VOILA! No more lead. Presto - severe, caked on crusted up leading removed in 10 seconds. (If you hold your barrel over a white sheet of paper when you do it, you will see what I mean about lead pouring out).

Us heavy cast big bore shooters been doing it for years!

That's sound advice nickE, I've seen these around before. I'll try it out running it dry next time I get some lead buildup and see how it works>
