Brent

Load from-a-disk said about .86 BC for that bullet.

Caution that is just the best guess I have, I pluged in 2778 muzzle with a .30 cal bullet 1.5" long and keep changing the BC untill the 1K Velocity was at 1808 FPS.

Buy the way I never thanked you for the 30-378 data you e-mailed me THANKS CAM [img]images/icons/grin.gif[/img]

Re: Denser core material?

Cam,

In theory, they said it's .91 BC but, I'd take an .86 BC and somehow try to find a way to make it work out. [img]images/icons/grin.gif[/img]

30/378 Wby data, no sweat, anytime. Want a copy of the PRL TC article I have here?

Jerry,

Why light bullets for target work? Recoil?

Brent, are you back now? I think everyone should read that article.

I printed a copy and I saved it in my e-mail so I'll always have it. [img]images/icons/grin.gif[/img] [img]images/icons/grin.gif[/img]

Re: Denser core material?

Brent, thanks for the article email. Really appreciate that. The fog begins to rise... [img]images/icons/wink.gif[/img]

Jerry, thanks to you for your comments. Question for you, not intended to create chaos: Why do you like the 'long light' for target work? The philosophy seems to favor form over mass in search of BC/lower Cd. Does that not compound yaw of repose issues? BTW, to my surprise, according the web site linked above, tungsten is denser than uranium by a minor amount. I gather it is more problematic to work with due to characteristics however.

Thanks to all.

Re: Denser core material?

Max,

You want to make your own TC bullets?

corbins.com/powder.htm

Here's the equipment you want. I'm going to contact them to see who's geared up and making them right now, and selling them. Powell River Laboratories is now Brown Dog Ent. from what I've found out, can't find anything on the net for them tho. I do have a ph# for them in California tho. It seems PRL was several thousand dollars behind on rent for their building for a few years, and finally lost it last year, about all I found on them.

Corbin has some great info in their site concerning bullet design, shape, stability and accuracy vs. high BC forms...
