28-32g 6-7.5 what powers/data are people using????

[vmobiler1]

Hi,

 

I have bought some reloading bits and made some cartridges as per the load data given buy the shop that sold me the gear.

 

12 Gauge

70mm case

26grains PSB2

CX2000 primer

32 gram No 6s

Gualandi V-Zero 23 wads

 

After firing and opening the gun it gives off lots of smoke when the carts are ejected it also leaves a lots of unburnt powder in the barrels.

 

I was informed to up the powder, so I have gone from 26grains to 27grains and it has mad no noticable difference.

 

I dont really want to keep upping the powder to get a clean burn so was thinking of changing powders.

 

What powder is everyone else using with good results??

 

I am looking to make 28gram 7.5s and 32/34gram 6s, if i need to I will but seperate powder for the two loads.

 

Any help or advice would be greatly appriciated as I am new ish to this and its not going to be a hobby for long if I keep buying gear that is just not doing the job.

 

Thanks in advance.

cannot find data for psb2 for 28gram.

first of all GREAT, you did some research got some credible data, and loaded it. that is good.

 

however, that powder looks like it will struggle with 28 grams of shot, the 32gram data looks like it has a little more scope, but as you have been told, upping the powder may have cleaned up the load. but in reality you just upped the powder only 3.8%. thats not ideal as it costs more.

 

personally i`m using ba10 and getting 1300fps at only 15grains. with 28 grams of leadshot. also i still use AS, because its value and i`m still loading subsonic 32g loads. where i have it excell in that application.

 

just use it for 36g loads and use those 36g loads for whatever, you`ll be getting better value out of that powder.

Hi,

 

Thanks Andy H, that is the same as I have but it does leave lots of unburnt power, this is not due to damp powder as it is stored in the house in a cupboard near the airing cupboard.

 

I was informed by the place of purchase to up the powder to help burn the powder by upping the pressure.

 

I was looking more for people that have tried different powder or have experience with this loads to see what they have tried and how they got on, maybe they changed power to a cleaner burning power or just put up with the dirty one???

 

PSB2 will not do data for 28gram loads as it is a slow burning powder and it needs to be faster for the 28gram loads.

Have you tried increasing the wad seating pressure?

 

What type of crimp are you using?

Maybe increasing the crimp depth a little will be beneficial.

Here is a small bit of Maxam data for 36 gram.

I use the Clay & Game data for PSB2 powder loading 34 & 36 gram lead loads and seems to work fine, cleaner than Blue Dot powder that's really dirty.

Not sure but from what you say you are using different case and wad from that listed in the data, I and a lot of others on here follow the data to the letter with shot shell reloads. Anyway just my thoughts but can confirm as I said above 34 & 36 gram lead loads in a 12 gauge work ok with PSB2.

Psb2 is not a 28 gram powder use Vectan AS express do

I use psb2 in a 32g fibre load and find it quite a nice load.

[Underdog]

Green dot is a bit dirty when using fibre wads, plastic wads and it burns clean as a whistle. Red dot is similar but better with 28g loads.

 

I did some experimenting today with an old can of Nobels 80 I got cheap. 25grains under a nitro card and fibre plus 32g of #2 shot, it too is a bit dirty so pressure is down a little but two crows were not impressed with it and at fair distance so I am fine with it. It just leaves a few flakes, not much really otherwise I would up the charge. It don't matter as it come cheap but it is not a favourite of mine as it is bulky and needs a heavy dose. To be honest it would of been better used in the 357!

 

If I was you upping two grains is what I would test next just to see if it will work and then next time get a slightly faster powder. Don't get worried about it being dangerous, you sound like airing on the cautious side of things, dangerous would be upping it by 5grains at a time!

Now UD, green dot is dirty when there is no pressure. You should know that.

Red dot was designed for 32g loads. In this app it excells.

 

Just because a load is dirty or clean does not indicate if it is safe.

 

A1 would be a better choice for 32 and 36 loads.

 

Psb2 can even handle Bigger loads. So makes me think it is Ill suited to 28 grams.

 

Psb2 can run 32 loads. But is powder heavy

[super sharp shooter]

To true cook at 32g you need 30grn of powder.

I just didn't have the data to hand.

Pressure is the key.

 

Pressure is always the key.

Not ideal pressure bud, there IS pressure or the load would not leave the barrel!

G,dot favours a plas wad evertime for a clean burn and it always struggles to clean burn even when pushing it to much with fibre wads.

Greendot just needs pressure to burn clean. Get a 32g load burning at 11500psi, and I'll be sweet.

Fullstop. Plaswad or not.

What cases do clay game recommend for 23/34gram loads as it says on my data sheet 70mm? I will be using different wads from the load data you gave as the loads I gave was for 32 gram also from clay and game. I did exactly what they told me and I done other searches on the net and found it is not only me getting dirty loads. I presume the larger loads will be cleaner as they will have the larger amounts of powder and pressure to burn cleaner.

 

What I was asking was what experience people have with the load I am trying to make, I didnt want to keep making bigger cartridges than I wanted.

Hi,

 

No I havent tried increasing the wad pressure... I will look into it.

 

the crimp is the one my mec 9000 came with.... sorry for my lack on knowledge.... I am knew ish to this.

Hi,

 

I will look into trying some Vectan AS for the 28 gram loads then, thanks.

Yes I am airing on the side of causion as I am new to reloading and dont want to overdo it and do damage to the gun or myself.

 

I will try upping it to 28grains and making some 34gram shell see how that goes.

 

Thanks

I was getting some unburnt powder when i had less powder in the load. So i decided to increase the powder charge and get the load tested and found the pressure was quite low with 26grn,but with 30grn now burns clean..

I was looking to make 32gram loads maybe 34 .... looks like that decision has been made for me. 34 it is then.

 

I need to find a nice one to try in the 28gram now.

As I am new to this .... does upping the powder that much not seem a little strange when the load data recommends 26grains? would it be better to find a more efficient powder.... I am asking this, not looking for an argument... I may be missing something thats all.

I like what your saying about better value for money ....

 

What I could do with is someone packing up and me buying lots of bits n bobs of them to try!

 

Oh and a few lessons in reloading data... as in how much can you safely change fro the recomended load??

[Guest cookoff013]

regardless of how experienced reloader you are, changing anything can and will affect the end result.

i would consider a primer change like for like, but only where the original data has the hotter type primer (hot type, not magnum)

 

the lead shot i`d change upto BB. but shot is measured volumetric in a re loader and by mass by a set of scales.

 

if you read the whole data set, it will pretty much tell you how good a load is. to do that i collect all the data i can for that gauge / powder / shotweight.
