See if you can scrounge some Swiss #1 to try. It's about 60 quid a kilo which is twice the price of Kranks but a far better powder in my opinion, but with half the charge you are currently using it would work out the same price. I use Kranks in all my larger calibres and revolver but love the Swiss in the 36. I was using a lee .350 ball but moved onto a Jeff Tanner .354 which is very slow to cast and trim (I tumble the balls to finish them off) and this has worked very well for me. I find the 354 quite a tight fit with a ten thou patch so you must have fun with a 360 and 12 thou. Next time down I'll chrono my pistol and see what I'm getting.

I get good accuracy with 13g of Swiss, .350 Hornady ball and 10 thou patch.
not too bad till i get around 7-9 shots then it needs more thump ,yeah it be interesting to see chrono resultsI find the 354 quite a tight fit with a ten thou patch so you must have fun with a 360 and 12 thou. Next time down I'll chrono my pistol and see what I'm getting.
Well I forgot my semolina today so I just whacked a few shots off over the chrono with 8.9gn of swiss #1, ten thou patch and a 354 ball. The average velocity was 1058fps with a few going over 100fps above or below. When I later weighed my remaining vials I found that my powder thrower is not as accurate as I thought with a full grain (by weight) difference from the mean which explains some of the flyers I've been getting lately. (my excuses book is now in the seventh volume).
What I thought was interesting was how close to the speed of sound this light charge is pushing the ball. I would suggest that 12gns would certainly be supersonic and anything in-between in the transonic region which can not be good for accuracy.
I will investigate this further and report back.
