but it's 490 ft lbs. 
Mag Safe has sold this load for a decade. Anyone who "thinks' that the .100" longer, stronger case of the 356 TSW can't get a 55 gr bullet, with a HUGE hollowbase, to 2200 fps in a 3" barrel is an ignorant fool. The cast bullet and lube,and sizing-diameter let you set up the optimal match of bore friction with pressure and velocity. Much of the problem with attaining really high speeds, in short barrels, is NOT high pressure,it's having the bullet leave the bore before you can GET enough pressure to get high velocity. You can overcome this tendency by using .001-003" "oversize" bullets. The large hollow cavity inthe basemakes more room for powder, it seals the bore better for the powder gases, it makes the bullet "nose heavy" for better accuracy and penetration, and it lets the bullet "swage down" in the bore, as need be,to reduce pressures. Too bad none of you <font color=red>*</font><font color=red>*</font><font color=red>*</font><font color=red>*</font><font color=red>*</font><font color=red>*</font><font color=red>*</font> thought of this, hmm?
