Does anyone know of a load for 40cal 155FP rainier ballistics with power pistol? :banghead:

Loading Data

We, at Rainier Ballistics, recommend using lead bullet load data when loading our bullets. There is no need for adjustment when using lead bullet load data. Our bullets are jacketed using an electroplating process and are softer than traditionally jacketed bullets; hence the recommendation to use lead bullet load data.

If you only have access to traditionally jacketed load data, we recommend a starting powder charge directly between the listed minimum and maximum load, and you may use published load data found in reputable reloading manuals.

A slight roll or taper crimp may be used with our bullets;

Overcrimping plated bullets may result in decreased accuracy, and fragmentation of copper plating.

LSWC 155 6.7 gr Alliant Power Pistol 1,084 fps 1.125" Fed SPM

Alliant only lists 155gr jacketed data (9.0gr @ 1.120") and does over 1250 fps from the G23. However since you're using plated bullets, I'd back off to around 8.0gr and go from there. At the same time, it depends on what kind of load you're looking for, whether you're wanting a more normal power level load or just something to mild to punch holes in paper.

Speer 14th ed. lists 8.0 grains of PP as a starting load for 155 g fmj. Hornady 7th ed lists 6.7 g as a starting load for their 155 g XTP bullet. So if it were me I would start with a 6.7 grain load and work up.

I shoot a lot of 40 smith and use power pistol powder. I've never shot Rainer bullets, but I have used Berrys plated bullets and they will lead the barrel if you try to use a heavy load.

I dont no how they put 8 at a starting load I have loaded that and it is very very snappy ejections where going outa site.Primers where showing bad signs I do not recommend the 8 load to anyone.I load that all the way down to 6.4 and found it is the a very nice in my gun.Talking about target loads here.

Rainier Ballistics, recommend using lead bullet load data

2004 Alliant load data has lead load data for 155/180 gr lead bullets. For 155 gr lead bullet, 10% reduction of 7.0 gr max would be 6.3 gr as start charge.

Hornady 8th edition

Power Pistol Hornady XTP 155gr

5.8-8.9 grains.

Lyman 49th

Winchester Silvertip 155gr -- Power Pistol
7.0-7.8gr

I have loaded many of those from 6.4 to 7.7 only use the 7.7s for home defence use the 6.4 for target and they work well in my px4f.I use the book on aol.

For Rainier bullets I cross reference Lee and Lyman manuals with the powder manufacturers website, Alliant in the case of Power Pistol, and start with a charge weight right in the middle of jacketed data. I've found that 90% of the time it produces a great load, other times I bump the charge up 0.1-0.3gr (depending on max listed) and find my great load. I'm not saying you should do that or that it will work for you. But it is a process that hasn't let me down yet.

FWIW, I load 155 precision black bullets with 6.5 PP @ 1..120 and get 1050 FPS from my XD

I have gotten excellent results with 8.5 Grs. of PP with 155 XTP. I do not use or recommend PP for plated or lead bullets.
