PowER Of The POWder
i am shooting an xdm 9mm and for a while was using 124g montana gold fmj with 5.8-6g of HS-6 to great success
i loaded some 147g cmj montana gold with 5.3g of HS-6 and it worked very reliably. i started to notice a trend where from looking at my Hornady reloading manual i need to use the maximum powder charge or higher in order to have reliable slide cycling with my handgun so i never get any jams or stovepipes or cases not getting ejected. Then..I ran out of HS-6. I bought some Hodgedon Universal. I look on thier website and it says for 147g 9mm to use 3.3g "maximum" charge to produce a supposed 870fps avg. ok...so i load a few rounds with the recommended maximum charge. I get mouse fart-like shots which fail to cycle the slide hardly at all. Every used case stays stuck in the chamber. This is with a completely cleaned and oiled handgun (xdm9) do they have any websites that have charge recommendations for NON LABRATORY SETTINGS? seriously. i think i might have to bump the charge up quite a bit maybe almost to 4g but frankly i just wonder sometimes. |

Hmm, Hodgdon Universal has a huge pressure jump between minimal and maximal, from 24k to 31k when only going from 3.0 to 3.3 gr. That does not sound like the powder to go to 4 gr with. I'd also pull some bullets at re-weigh the charge to make sure you're not low, it looks like a very charge sensitive powder.

My Lyman manual shows 3.5 as max with a 147TMJ. 3.1 is 19k psi, 3.5 is 29,200. It only pushes it to 924fps though.
It also shows HS-6 as 4.8-5.8gr. |
