I'm switching from 231 to unique loading 124grain berrys round nose and 3 different books call for 6.0 grains for a 9mm,but it doesn't look right.It almost fills the case.It looks like if I seat the bullet it will compress the powder to some extent.On 231 it called for 4.5 grains and still had plenty of room.So what gives on the unique?I
I'm afraid to load any without checking with more experienced loaders.Thanks. sj

I'm not sure which manuals your looking in but 6 grs. of Unique is a pretty stout load in 9mm with a plated bullet. Alliant's lists 5.8 gr. as max with a 124gr. Speer Gold Dot.

Better off to start around 4.5gr. and work up slow. I user 5 grs. of unique with Berry's 124gr. H-P with good results.

After doing more reading I found out I should start out around 4.5 to 5.0.I was way off,I'm glad I checked first before I started loading.Thanks. sj

No problem sj glad to help. I think you will enjoy Unique, it doesn't meter as great as other powders but like you found out it is hard to overcharge and it gives great accuracy.

I'd start at 4.8 grains and work up. At 5.0-5.1 it makes a nice load for 124 gr. bullets.

I load Montana Gold 124gr FMJ's with 4.7gr's of Unique at 1.150 OAL. Its a soft and accurate load. It functions 100% in my 3 9mm's.

Edit:
I should also add that this is a VERY clean burning load.

I started out at 5 grains and 1.150,I'll see how that works out.I've always used 231 before.This is my first try with unique.I couldn't find any more 231.

Not to hack on you, but theses "liitle mistakes", can cost you a gun or a hand. PAY attention to your load dat a7 componets used. There are few little mistakes in loading handgun rounds. Plated bullets load closer to lead data, so 6gr is running well into +P range of pressures. Check more than one data source, average the data if it is confliciting or use the lower charge wt & work up. Finally, yes, Unique is a bit bulkier than W231 for the same charge wt. Unique is also a slower powder & you will need slightly more to get the same vel/pressures as the W231 or a faster powder.

I just loaded some Berry's 124gr RN with Unique at 4.5gr and OAL at 1.150. Great and accurate load for my guns. I loaded some at 5.0 before and had some jacket separation so I toned it down some.

Berry's are plated, so if you are getting plating esparation, you are crimping too hard. I view 5.1gr as about max for a 124grTC plated or lead bullet @ 1.1060"OAL, running about 1200fps in a G17/LW bbl.

Fred,Thats why I was leery.It didn't look right.When I don't think something is right I question it.I double check all my charges.But thanks for the advice. sj

Instead of starting out at 5 gr's why not take the advice others have given you. 5gr's at an OAL of 1.150 puts you above a mid level load.

4.5gr's-4.7gr's is a great starting point for 124gr plated or jacketed round nose bullets at 1.150 OAL.

Many of us have proven these loads. My suggestion, start at 4.5gr's of Unique at 1.150 OAL. Then slowly work your way up. You'll find that you'll be very pleased with a 4.7gr load.

I'll take your advice and drop to 4.5 to start out and see how it goes.Thanks. sj

I load 124gnTC Berrys with 4.7gns Unique. Oal 1.045. Will punch out a silver dollar hole at 25 yards from a rest and is very accurate. Went up to 5.0gns but was getting signs of cratered primers. Primers look normal at 4.7gns.

I've loaded over 1000 of Berry's 124gr plated with Unique @ 4.8 gr. Works great. Yeah, the case is pretty full. Makes is easy to see you have a good charge!
