I would think they would work fine for plinking,plenty large enough at.311 to fill the micro-groove and hard enough basically Lyman #2 alloy to give some good grip without skidding on those shallow lands and grooves,they could have a lower BHN of 12 or 13 and still work just fine for plinking.

Not sure how the bevel base will affect anything maybe not at all I shoot my 170 gr. home cast gas check bullets with the gas check left off at 1250+ fps. with no issues so it's possibly a moot point.

Here is another option basically the same bullet that you can apply a GC to later if you like using a Lee .311 sizer if you want to push the bullet a little faster for large game hunting purposes or you can shoot as is for plinker small game loads,there about $8 per 100 cheaper but you have to buy 500. http://www.laser-cast.com/30Cal.html

I'm guessing you aware of the different loading practices for cast bullets over jacketed bullet?
