update on keyhole 32-40

[BADUNAME71]

I got new bullets in yesterday from Missouri Bullet Co.
They are 170 gr hard cast .322. I measured them with both digital caliper and0-1 micrometer. They measured just over .321 on both.
I loaded up 4 cartridges with 13 gr. 4227 powder and this is my result I feel a lot of my problem was wear in the bore and not getting a good reading whenI slugged the barrel. If you saw earlier posts, all 4 shots with 165 gr, .321 lead cast were hittlin target sideways and I could only change it by reducing powder charge drastically.
I'm starting to get happier with this rifle.
Thanks again to all who helped walk me thru this issue.

Hopefully it starts working for you

13 gr. of IMR4227 is the start load for a 170 grain jacketed bullet. Not a cast bullet. Where's your data coming from? Isn't dangerous though.
My old Lyman book has data for a 164 grain with gas check cast bullet. That'd be close enough. IMR4227 12.0(1195 fps) to 15.4(1488 fps).

Sunray, actually I got the load data from Lee reloading that came with the die set. Also got some information/suggestions off this forum. I did load 5 with 11.4 gr 4227 which also came in the paperwork with the Lee die set. I am pretty happy with the progress I'm making.
I am going to pull the 165gr lead bullets (dia too small)from the 40 rounds that I ordered from Gad's reloading, dump the powder as I am not sure what is. That will give me 40 more pieces of already primed cases to load with the 4227 or Trail Boss. I am really pleased with the bullets I got from Missouri Bullets.
My next step will be to try to resize 32 special brass into 32-40 cases. Resizing 30-30 brass is pretty tough and not having a carbide die does not help. Thanks for the advice,
