Is faster better?

[74honker]

Uhhh, i would argue with that, and so would others i know.
Yes, there comes a point where higher BC will overtake a bullet having less fired from the same gun.
BUT, at what distance will that take place?
How far have you ever killed an animal?
Velocity always rules, and when coupled with a high BC it can rule even better.
But a higher BC bullet with less velocity than a lighter version is only fooling one person.
At what point does the higher BC bullet in (your) gun, overtake the lighter faster one?
Probably further than you might think.

The point at which all this happens has plauged my brain for quite some time. Is there a "rule of thumb" or special mathmatical equation that's probably over my head that one can use to find this point? Or do you just have to burn rounds to find out for yourself with each combination?

Depends on the range 500 yds versus 1000 I'll take speed any day over bc too a degree maybe past 500 yds but then I would compare the differance in bc and vel too see if giving up vel makes a difference I run em as fast as I can

Smart man

I don't think that you will be displeased with a Berger or eld-m 180 grains & up in that cartridge. With a 26" barrel, I think that you may be able to push a 180 to 3050 fps with that cartridge and a 190 to around 2940. It's highly likely you will find an accuracy node around 3050 fps. There should be one or possibly two accuracy nodes between 2800 to 2940 fps with the 190. Of course the higher B.C. bullet at any of those velocities I mentioned is going to resist wind better than a lower bc bullet. Any way you slice it, a 190, 195 or 180 pushed to those velocities is going to be impressive granted that you have good accuracy along with those velocities. They may all shoot great for you but more than likely, the rifle will prefer one of these bullets over the others even if there's just a small difference in group size among them.

Yes it is but if you don't know what your velocity would be for any said bullet you're still just making a guess. I've had good luck with JBS once I have a load developed for making drop charts. My question is whether there's a way to get and or make an educated guess BEFORE you invest in new bullets and whatnot only to find out it's no better than what you already had running.

To answer your Question,..
IT, "can" be, a "Wash",.. sometimes,..
I shoot,.. a .270 WSM, launching, a 140 Grain, Berger Classic Hunter bullet, W/ a .528 BC at, 3,185 FPS
My son shoots, a lowly, slowpoke, 7mm-08 with, 168 grain HVLD, Bergers, W/ a .618 BC at, 2,760 FPS ( W/ StaBall powder )
Somewhere after, about, 600 yards, the "SloPoke" catches up to,.. "the LAZER" !
Both, our Bullets, EXCEED, 2,000 FPS at, 800 yards and with, the added weight of, his Bullet, it most probably hits, HARDER !
Go to, the Berger Ballistic Calculator to find out exactly, "where" his bullet catches up to, my MUCH Faster Bullet, if, you're really,.. interested.
Both, of us, shoot, 7.5 Pound Tikka's and the recoil, ( both, UN Braked ) feels about,.. the same !

Ill take a hammer bullet traveling faster than the speed of light any day over bc

It's considerably slower, but still, this is from a half-ounce sized bit of plastic at 15,000 mph...


impact..

Yes, but it may be difficult to collect your venison..

I am still new to reloading and long range shooting. The more I learn the more I realize I have a loooooong way to go. So this might be a simple/dumb question. But is shooting at a higher fps better? I understand that the hotter you shoot the shorter your barrel life, more powder means more kick, more powder also means more $$ per shot. So excluding these why wouldn't I want to shooting 3200+?

My current build I am working on is a Sherman Short 7ss (still waiting on my action). I have a Preferred blanks barrel, purchased some berger 190's, can't find any 195 eol's, and have some h1000 that I plan to reload with.

Any and all information/ knowledge is greatly appreciated. Thanks guys.

Whatever charge weight is most accurate with your H1000 and the bullet you select regardless of velocity. What good is a 3250 fps velocity vs a 3020 velocity that shoots 1/2 the size group at ranges past 500 yards? Now I will go out on a limb and say I do not worry about B. C. until I go past 600 yards. If a caliber of hunting rifle does not have the energy past 500 yards to take a Mule Deer then why worry about BC, If your shooting paper way out yonder or truely long range hunting with a big magnum then yes pay attention to B.C.

From what I have read on numerous forums and such......speed is king. What does baffled me, why try to push for greater speed than the round is normally? That " I want 300 mag velocity from my 30/06". Why not just start with the 300 mag? I guess then it turns into " I want 300 rum velocity now".....
