Ha, Ha  How old is it? Well I bought two 10 pound containers of 452 when I was shooting IPSC, IDPA, Plates, Pins and B Cup. I used it in all of my 45s including the 25-2. At 4-5.1 gr it lasts a long time. But, I had a 100, 50 and 25 yard practice range in my back yard and between matches every weekend and practice, went through 15k per quarter and is how I bought my componets, in 15K lots. But I did find that 452 worked with every gun and every bullet weight, from 200s to my 252gr pin bullet and it gave you a nice push recoil rather than a slap.
Thanks for the info on the HS powders.
