What would the ballistic coefficient be??

[Win94]

Fellas what would the BC of this bullet be?? Round about guesstimate?? .458 " cal 405 grain????

 

[Levi Garrett]

It would not be of concern , like a freight train, it will still do business And since BC, is for the long flight jobs, one does not need it with that baby.For numbers sake .150-.160 BC. Nice bullet

The 405 gr bullet from a .45 caliber RCBS mould has a BC of about .303.

 

[Win94]

...........................Thats a big diff at 150 yards.


............150 or .303???

 

[Levi Garrett]

I just took a shot in the dark on that Win94, It might be higher than my numbers

Lee lists a similarly shaped bullet at 0.225. At any range you will likely use this bullet, it will hit hard enough to make spotting easy.

i would use about 320 as the BC for that bullet.....I don't want to hijack this thread, but wonder why you are using a, plain bevel base bullet? The bevel base may be o.k. for plinking loads but for heavy loads you will get better accuracy and less leading with a good square base bullet or better still a gas check bullet.The bevel will encourage the hot gases to try to go along side the bullet causing leading, a bullet slightly small in dia. will amplify problem. The hardcast bullet will not bump up to fit the bore, this is why sometimes a softer bullet does not lead as much as hard one. The bevel is really there so that production casting machines will drop the bullet from the mould easier, and help speed production, it is not there for your benefit!

................I am getting 1690fps with no leading and 1.5" at 100 yards so far. I am not a hard cast newbie, i was just wondering what people thought the BC might be.

I think Ben is about right for the BC of about .320. No need to get into the rest because that is not what you asked about

 

[todbartell]

.281

 

[Win94]

281

...............and change???
