Is the Hornady Interlock in the same class as the power point and federal soft point which I'm guessing is a speer bullet? Can you buy the Interlock preloaded?
I don't have the correct answers to any of your questions...sorry.
As for the premium factory loads you mentioned in an earlier post...my suggestion...try them but shoot what works best in your gun. I tried a box of Federal Premium loads from a Striker .243 several years ago and the bullets keyholed at 100yds.
At half the price per box...and if the only accuracy diff is .5" at 100yds...I can tell you that I'd be shooting the cheaper stuff. Half the price means twice the amount of shooting you can do.
rigger...I also shot a LOT of 130gr bullets from my .30 cal handguns...32-20, 30 Herrett, 30-30 and 30-30AI. Once they get above the .308 level of performance though I jump to the .150gr offerings.
