For a 240...
I'd prefer something along the lines of a RFP or WFN for lead, or a JSP for jacketed.
With rifle cartridges, a round nose generally aids expansion of jacketed bullets (rather than a spitzer profile). But, it doesn't help much with handgun cartridges.
I'd rather have a wide meplat flat point, than a round nose. ...But, accuracy isn't affected much, either way.
After their mention in a recent thread, I've really been eye-balling the Cast Performance 255 gr WFN
. It looks like a tasty little treat.
But... I won't pay anything near what Midway wants. I need to find a similar bullet mold, and cast my own.
I suspect that the heavy nose would help maintain stability, but there's no way of knowing, without trying them.
