243 vs 6mm arc vs 6creed

[Marshfly]

can you recommend a ballistics calculator I can play with to figure this out?

I use Shooter on my iPhone but there's some good online ones.

I use this one at the desk a lot.

ShootersCalculator.com | Ballistic Trajectory Calculator

Calculates the ballistic trajectory of a bullet fired from a rifle, handgun or other firearm. Produces a ballistic trajectory chart and table that shows the drop, velocity, kinetic energy, windage, and trajectory of a bullet.

Federal ballistic calculator is pretty simple to use and pretty accurate

When I am comparing quick numbers and researching cartridges, the federal app is where I turn to as well. Takes seconds to change the data input and is very simple to navigate.

Very very close results to my kestrel 5700

I came across this thread because I'm trying to figure out which of these cartridges I want (with the addition of a .223). My variable is that I live in CA and have to use lead free ammo. I'm looking for this to be primarily for deer. How would this variable affect your decision?

Not sure where you landed but I have the howa mini 6arc and also live in CA. Finding lead free ammo for it isn’t easy if you don’t reload. Limited to custom reloading websites, or the two I found you can get factory ammo from are Fort Scott Munitions tumble upon impact and Gorilla Ammo, they have a fracturing lead free bullet similar to Lehigh.

6mm GT is another possibility -- same case capacity to bore area ratio as 6.5 CM:
