How was your accuracy?

How was your accuracy?
Good, I need to do some more testing, as i was pressed for time. But the 5.8 load from 25 feet , one ragged hole. The others I didnt try any slow fire accuracy testing, just chrono and functioning

Here is some 9mm comparisons. I did a dead comparison to CSB-1 from Hi-tech and a friend had a can of NR485.. they looked alike visual wise.

125 RN, Mixed brass, Lone Wolf Glock Barrel, Winchester SPP's.

NR485 - 4.1 - avg 1083
NR485 - 4.3 - avg 1108
NR485 - 4.5 - avg 1144

CSB-1 - 4.1 - avg 1073
CSB-1 - 4.3 - avg 1101
CSB-1 - 4.5 - avg 1129

Does a volumetric powder measure throw identical weights at the same volume settings?
The results are close enough to be slightly different batches of the same powder or just tested at a little different temperature.

[sargenv]

I don't have a answer to that question since I dialed in these weights on my Dillon measure to throw to those specific weights.. I have no idea if the volumes were exactly the same and really have no way of telling in an easy way.

[tazman]

Were the settings different for the same weight of the different powders?
Do you have a stand alone type powder measure? If so, set a volume and measure it using both powders.
I have never worked with a Dillon. I have no idea how hard it would be to change powder in the measure and throw a couple of charges without changing the setting.

[sargenv]

Since I no longer have any more NR485, it wouldn't exactly work for me.. I did the research on this last spring/summer. By the time I'd aquired the CSB-1, I'd given the NR485 back to it's owner.

I didn't think at the time to do things volumetrically since I only go by weight.. I don't make settings on my measures to repeat them later. Sorry :(

[tazman]

I was just trying to determine if the 2 powders were physically identical as well as the results being so nearly the same.
Thanks for your information though. I may need to invest in some of that powder in the future.

So is it safe to say that you could use NR 485 starting data for CSB 1 powder? I know where I can get csb 1 locally but he does not have much load data on it.

thanks tazman. A guy at my local sportsman's club claims he is loading it in 20 and 12 gauge. I have found in the past it is hard to find a powder that works in both gauges well. I have saved that data, just wondering if this could be a good all around powder it seams very versatile.

[tazman]

I don't have shotgun data for CSB-1 but it wouldn't surprise me that it works. Look at Red dot, Green Dot, and Unique just to name a couple. They work in shotgun as well.
Most of the powder I have been using this last year was originally designed for shotgun.

This thread, and post #28 gives a lot of data I worked up with CSB-1.. It had some NR485 comparison data in there also.

Thanks for posting that. I remembered the data, but couldn't remember which thread it was in.

I posted this before but this thread seems newer:
Hello, brand new here, brand new Glock 19 owner and Brand new to reloading. Anyway I thought I might contribute a little and also gather feedback as appropriate. With lack of powder in the area I ended up buying 8 pounds of CSB-1 from American Reloading.

I worked up the following loads for my 9mm.
Xtreme Plated 115gr, 3.8gn, oal 1.13....I couldn't get it to cylcle.
Xtreme Plated 115gr, 4.0gn, oal 1.14....Seemed to work nicely with less recoil than my regular ammo.
Xtreme Plated 115gr, 4.2gn, oal 1.15....I couldn't tell much of difference between this load and the previous.

Since I don't have a Chrono I may just stick to the 4.2gn for a while and just adjust the OAL. I wasn't sure what to use for OAL so I went long just to be safe.

Open to any advice or criticism. Its the only powder I have ever used so I don't have much of a baseline.

1/2gr window on most of those charges is pretty tight. Be careful with that stuff seems to be the word

[tazman]

It isn't uncommon to have half grain windows in 9mm. It is a small volume case at high pressure. Small changes in seating depth have a large effect on pressure. It can be tricky so you need to be careful.

[anoroc751]

tazman, thanks for the warning on seating depth. Since I am new to all this perhaps I will just leave it at 1.15 OAL until others can provide more information. I saw someone post somewhere else that they were at 1.13. I emailed the seller to see if they had anything on seat depth as well. Thank You.

[tazman]

In 9mm, seating depth is often controlled by what depth the boolit will feed properly through your pistol. If the seating depth you are using works, then you have no need to seat deeper.
Each gun makes it's own rules about what works best. Experimenting with small changes in OAL can sometimes show a particular length is more accurate. If you are working with midrange charges, playing with the OAL should be safe as long as you don't go crazy with it.

Indeed and with 380. I was just pointing it out to the OP and others that may not load for the smaller calibers often

Hello all, ive been eyeing this powder for my 9mm loads. I use the lee .356-120tc standard lube groove with pc. My oal is at 1.080 to pass the plunk test. W231 works great but since this powder is rather bulky, im wondering if enuff will fit in the case to get velocities of 1100fps. I really dont want to buy a powder that wont work in that caliber as i have plenty for my others. Anyone here have any chrono data with a similar boolit, caliber combo? Id appreciate any feedback i can get. Thx
