Unique in 9mm

ECLIPSE45ACP · April 18, 2007, 09:04 AM

Anyone notice that unique practically fills a 9mm case? is this compressing the chargewhen seating it at 1.160? it is a ranier 124 gn FP any input would be appreciated.

Best way to know for sure is to do some measurements and be sure...

start with a charged case of your load in question. Take your calipers and use the end opposute of the calipers as a depth gage to see how much free case is left (the end of calipers have a rod that slides out the middle and this is used to check depths from a zeroed set of calipers). Now take the bullet overall length plus the case overall length and subtract that from the cartridge overall length. If the difference is greater than your depth measurement (of free space above powder), you have a compressed load.

That's my engineer hat for ya. Let me know if ????

it looks like other people say unique is compressed, but since it is such a low density powder it is ok

I've used 6 gr of unique in 115 and 124 grain without problems.It definitely fills the case.For practice rounds in 124 gr I use about 4.7.I've started using power pistol in all of my 9mm stuff-it measures better for me.

For some soft shooting 9mm,try some clays-not the universal clays.What surprised me,was that some of most accurate loads came with red dot.

Reloading 9MM. I have been using Unique as follows:
1. 5.5 gr with a 115 gr Rainier rd nose.
2. 5.0 gr with a 125 gr lead rd nose.

Both these loads shoot well for me.
