Need some info

Does anyone out there have the ballistic coefficient's for these 54 cal bullets? The310 grain Buffalo Ballet, and the 410 grain TC Maxiball.

I have the new Lyman ML Manual and I think they are in there. Will look tonight for you. Chap

54 Cal, 338g Buffalo Ball-et has BC= .083 and SD=.164

54 Cal, TC Maxi 430g has BC=.150 and SD=.207

I don't expect that the 310g Ball-et is that much different or that the 410g TC Maxi is that much different. Chap

Thanks for the info. The 310Buffalo Ballet is a round nose like a round ball with short knurled sides and a hollow base and made a good showing in the testing my son did. The 410 Maxi is a home cast that I thought would be 430 but they weigh in at 410 +/- a bit. The numbers should be close enough, thanks.

Yep, that is what the picture shows. I can scan it for you tonight to verify. Chap

Thanks but don't worry about scanning it, these numbers are close enough for what I need. I'm just doing a little extra data crunching of my own on some of the data my son has got from his science fair ballisitcs experiment. I hope to have enough data from him in the next few days to post some of the results. Have a good day.
