I have no intentions of getting a can for mine but I will say 357 handgun bullets are crazy cheap and 110 XTPs sub sonic are not overly loud and very little recoil (feels like a 22 mag) and plenty accurate at 50 yards. Fun to plink and maybe quasi practical as a small game round in my 16" barrel 358 win.
I couldn't find the post on the cast bullet forum I was looking for but here's some links you might be interested in. Lot's of subsonic loads and talk.
how short is the barrel, Trail Boss Blue Dot just to mention 2 there are a number of powders that will achieve what you are looking for I shoot a 308 win at 1050Fps and a 35 Remington reduced with PC pistol bullets real slow 10" to 15" barrels
if you want change you have to put in your 2 cents, you can't just sit on the sidelines and whine
