RCBS 243 Specialty Bullet?

[Casting Timmy]

I just got a midway catalog in the mail and have been looking it over. It looks like there is a 243 Flat nose gas check @ 100gr in the RCBS specialty rifle bullet molds section. Has anybody shot these or seen them?

Just really curious of what they are.

I have this mold, just got it last month have not had a chance to cast any yet. Have found a couple of recipes for it in the forums. I looks like a .243 bullet that has had to tip cut off, radius tapers a little slower. Only place that I can find gas checks is at Buffalo Arms Company.
