Ballistic Coefficient
Anybody got a clue as to the BC of the .457 slugs? Google isn't giving me much info. I picked up my Texan today and included in the deal were a bunch of slugs. Most were from Hunters Supply, the 350 mostly. I'm looking to get an idea of the trajectory of these as well as ones from Mr HP in the 255-280 range.
There were also some BT's, 415g I think Thanks |
Hm, think its hard to tell without know exactly which slug it is. Are you casting them, or are they pre bought ?
|
Oh duh, just realized you mentioned they are HS. Let me see what I can find

Within Chairgun pro app there is a BC calculator. If you know the velocity and the drop at a given yardage it will calculate BC.
Chairgun pro is a free app on Itunes I would also recomend a paid app called StrelokPro. By far the best ballistic app I have tried it also has a BC calulator. |

I personaly like the 200gr HP from Hunter supply. First 3 shots average 980 fps 430 ftlbs. Aprox BC of .14
I think it is a good ballance of Power and shot count. 5 shot string 997,984,968,952,945. With this bullet I was able to hit a milk jug at 300yrds. |

I was figuring 2 shots with a follow-up a bit lower, but 5 w/i 5% would be fantastic |
Yes 3000 fill.
