Pulling hair out. Power pistol and Berrys 155gr .40

Does anyone have a good starting load for Berrys 155gr bullets with Power Pistol.

Lymans lists 7.0 Starting, 7.8 Max with 155g jacketed Silvertip
Alliant lists 9.0 Max with 155g GDHP
Berry's says "When loading plated bullets we have found best results using low- to mid-range jacketed data in the load manual."

Two questions:

Does anyone have any published starting loads for plated bullets?
Is it possible to get into a low powder/high pressure situation with Power Pistol?

Thanks

Data for Berry's bullets can be hard to find. Sometimes you just hafta find a comparable bullet and work your way up slowly.

I use them in my 10mm, but not the 155gr... I have data on the 180gr, but it is very limited.

Check this 2005 Alliant Reloading Guide (before they only list data for Gold Dot bullets which they don't even try to keep available for handloaders):
http://www.castpics.net/LoadData/Fre.../Alliant05.pdf
While they don't list data for 155 grain plated bullets they do list data for Power Pistol and 155 gr. Lazer Cast lead bullets. They list 7.0 grains of PP for their lead bullet which should be a safe level for plated. Only load I use with Power Pistol and 155 grain bullets is for Hornady's 155 XTP jacketed bullet. I load it at 8.0 grains of PP and get 1140's fps in a Glock 23. Don't go near Alliant's maximum data for GD's at 9.0 grains. Much too hot for plated and probably too hot for the GD's. I'd try staying in Lyman's range for PP data with your Berry 155's and would start with their start charge and work up. Scroll down past all the shotgun data to get to the pistol data and rifle. Alliant's old data guides were more useful before the switch to all Gold Dot bullets which as I mentioned, they won't keep in stock for reloaders.

Thanks.

I loaded 20 rounds with 6.8 grains. I will give those a try on Wednesday.

Actually Berry's states to either use lead data or mid range FMJ data as max. It wouldn't hurt to work a few up with 7.0 and 7.2 GR. I all to often had made one charge to find it too light and had to go back and work up so making a few more rounds incrementally might save you a trip or two.

Also it is best to have access to a Chronograph. They can tell you a lot about how hot the load is or isn't.

The only manufacturer that I'm aware of that specifically lists data for
Berry's bullets is Hodgdon. They have 155 gr 40 data for 14 different
powders in the IMR/Winchester/Hodgdon lines.

You might be able to find a load there, and cross it to a manual that shows
both that powder and Power Pistol.

The new Western Powder's #5 load guide has pressure tested data for both Berry's and Ranier plated bullets. I can also recommend one of the best powders for .40 S&W accuracy, Ramshot True Blue and it can be used to load any handgun cartridge. Often times exceptionally. www.ramshot.com

Thanks!

I should also add that these 2 loads both shot great, very accurate, light recoil, and clean.

Looks like you have successfully attained the data needed for a good load. Congratulations! Now let the hair grow back!

You might add a bit more powder and see if it shoots better at about 1050 to 1100 fps...
