9mm 147 gr Loads

[roval]

i cant recall where aa#5 and unique is compared to w231 in the burn chart but those are the 2 powders i use for plated and powder coated 147 gr bullets which is what i load for my 9 mms(multiple czs and xdm).

Remington hemispherical base? That's one ugly bullet! Golden Sabers aren't like that are they? Natchez used to carry these, but the page is 404 now. WTH?

Welcome Aboard !

• Be aware that if your gun has a Match Barrel or is a CZ, striker Springfield, or other tight chambered pistol, then not every 147gr bullet offered for sale can be loaded for your gun. That makes 147gr a poor starting choice for a new reloader.

• WST and W231 are not generally shown for 147gr bullets because heavier bullets generally like slower powders. The loading manuals are showing what is preferred by the general population of shooters. Those faster powders can be used, but it's a specialty load generally reserved for competition, not general plinking. And too, the load range will be very narrow. Something like 0.3 to 0.5gr instead of the loads listed in your manual that are 0.8 to 1.5gr. That being the case, most of the people using those specialty loads 1) have generally been loading long enough to greatly refine their load process, 2) have lots of experience with their powder measures, and 3) are generally using high accuracy equipment. So again, your powder/bullet pairing is less than optimal.

► You'd be better advised to start with a 124gr bullet and W231. That's a classic pairing that any pistol can accept, and the load range is super wide so that beginner errors don't mean much. The likelihood of trouble in one or both of these areas is a genuine reality, so I'm just reporting where your education hurdles and safety limits lie.

You may be suffering under the false impression that all 9mm guns are made alike. They are not. There are HUGE variations in auto pistol chamber dimensions between brands. We'd really need to know your exact bullet and exact make/model gun to take you any further.

Hope this helps.

I am glad you mentioned 124 grain 9mm and Win231 as a pairing. I have plenty of components for 9mm including 124gr FMJs and a good bit of Win 231 that I use for .45 acp. Lol, I have a bunch of primed 9mm brass but have yet to load a single round. I also have some Bullseye, Unique, and CFE pistol.

It looks like it will seat deeper in case and increase pressure maybe?

It may or may not. It really depends on what you end up with a COL for your gun(s). Many of us load bullets that aren’t described in the published data. When that happens, we look for a similar bullet technology and similar weight. That’s our starting point. The COL for that bullet in the published data is a guideline in this case, if you can load at that or longer, and your bullet is close to that bullet’s OAL, you’ll be fine. If you need to load shorter, then you need to reduce the starting load.

Load to 1.10. 4.0 grains WSF, or 3.7 grains of 231. I prefer processed brass and CCI primers. Neither load is near max-Both have been proven very accurate in numerous firearms.

YMMV
