9mm 147 gr HP gas check

making it slightly bigger in dia means you could also use it in .38/357 when sized correctly.

I’ve been reluctant to jump in here because I didn’t want to high-jack your thread, but I have to agree with Dragon on the bevel base. The 9mm case has a very limited case capacity, and it’s case walls taper, and get thicker after a very short distance, so a flat base design can bulge the case and make chambering difficult. That’s why almost every 147gr bullet design I know of has a beveled base. I can’t speak for Al, but he seems to be able to make plain base and gas check designs without any problem. I would think he could also do a bevel base on this one as well.

My other question is about the 160 gr bullet weight and length. I think something this long and heavy would eat up a lot of case capacity, and really cut down on the velocity you could achieve without causing excessive pressure. I would really jump in on a design that cast a FP bullet of around 147 grains, with a HP of about 140 grains, something like the Lyman #356637, except at a .358″ diameter with wheel weight alloy. See: http://www.lymanproducts.com/lyman/bullet-casting/mould-details.php?entryID=6 .

If anyone would be interested in something like this with a FP for IPSC, or with a HP for defensive use, I’d be happy to start another thread for that, so I wouldn’t interfere with your thread. What do you think?
