[QUOTE="ohnomrbillk, post: 1374070, member: 2985"] I won't claims on BC of anything I produce. I will, however, give you all the information you would need to plug the numbers into JBM and determine what it thinks. The boat tail specs of mine are standard Corbin [URL]http://www.corbins.com/specs.htm#rbt[/URL] Using Corbin's diagram and specs A: 0.375" B: 0.345" D: 0.279" L: 0.234" Caliber: 0.375" Meplat diameter: its as sharp as a thumb tack. I used zero, but it has to be something Ogive type: I used Secant for the software, because hybrid isn't an option Base diameter: 0.744 calibers Rotating band diameter: 1.000 calibers Bullet weight: 435gr Nose length: 2.903 calibers Ogive radius: 14.000 Boat tail length: 0.620 calibers Total length: 5.680 calibers Specific Gravity: (it defaults to 10.70, but I have no idea if it is correct) I don't have any Chinchaga's in front of me, but just eyeballing it, their boat tail is significantly longer. With the same lack of precision, it appears the nose is very similar to mine. I would guess the only difference is they have a longer boat tail with with proportionally shorter bearing surface. This is only a guess based on pictures posted online. As for watching me make some bullets, I'd be happy to. I recently moved to NW Missouri and am not set up to swage yet, but I'll let you know when I get settled in. I'm just a hobby swage guy that hasnt been into it very long, but i'm happy to share what little I know. That said, I can PM you some online links that guided me, if interested. [/QUOTE]
