Unique powder data.

Post by screenerglenn » Thu Feb 04, 2016 7:01 pm

I have finally run out of my HP-38/win231 . There are two pounds of unique in the safe and I started looking for loads for 9mm. The information I have found from several on-line sites and my reloading manuals can't seem to agree. Hoping to get about 1000/fps with berry's plated 124 gn RN. Recommended loads vary from 4.2 to 5.8. So, fsn brethren, any experience with this powder for 9mms ? Load suggestions ? Thanks, glenn

I have a 1988 Hornady Book that calls for 4.4gr at 1000fps. Max is 5.1gr at 1100fps.

That sounds like a safe start. Strange how some manuals go as high as 5.8. The diversity is scary

A chronograph is your friend.
Trust no one, especially load data that conflicts with other load data.
When in doubt, work up your own loads.

When comparing all those sources, is the exact same bullet being used?
Not just weight, but design and shape, too?
Several types of bullets can have the same general look to them but with very different load data.
For example, a 124 grain hollow point and a 124 grain round nose will have very different load data.

I don't have a chronograph (but my neighbor does) . Just to be safe I'm going to make a dozen of various loads starting at 4.0 and working up to 5.0 in .2 increments. Hopefully I can get to the range this weekend.

Went to the range with loads of 4.2, 4.4, 4.6, 4.8, and 5.0. The speeds were as expected on my neighbor's chronograph (thanks Nick). .Starting at about 880 fps up to 1150. It appears that 4.4 is going g to be the best load. I was surprised at how inconsistently this powder meters. With the HP-38 the drops were very consistent, but the Unique was off as much as .4 gn between drops. I am very redundant in the way I rotate the handle on my powder dispenser so I don't think it's my technique. The rounds felt a bit snappy, maybe a characteristic of this product. As soon as I get my hands on my preferred powder, this will go back in the safe.

If you run across some Winchester AutoComp you might pick it up. It meters as well as HP-38 and seems to burn pretty clean. It is a lot easier to find than HP-38, which is also my preferred powder for 9mm.

I haven't loaded with varget yet, there is a lot of data out there for use in 9mm. Found a pound of auto-comp and titegroup at bass-pro yesterday. Is there a problem with varget for pistol calibers ?

I am not aware of any pistol loading data for Varget. it is a preferred rifle powder for 223 with heavy bullets. AutoComp and Titegroup are both good pistol powders. Be careful with the TG as it is easy to overcharge with it. I would also recommend it only with jacketed bullets as I have seen people have leading issues with TG when not using jacketed bullets.

Thanks for your help. I'll be staying with autocomp for now.
