Party-on
In an AR platform Leheigh has some interesting offerings. Need to look to see if any are for lower velocities or maybe you should give them a call.
Of the two you mentioned I think the Partian may actually be softer for initial expansion and as MD pointed out will give the deeper penetration but they are very close and the AccuBond may tear up more critter on it's way through. I am shooting 250-260 grain versions of all three and they all perform well. I have yet to find a bad bullet in 375 caliber. As some one mentioned the 235 Speer is darned good for the price and especially at the lower velocities bear worthy.
