Rather than start a whole new thread, I'll try here first. Anyone calculate the trajectory of this caliber? I've googled but never found much.

^ that's gonna depend completely on the load.... Find which bullet you're interested in and then google "free ballistics calculator".

The 55gr NBT will be very different from a 100gr SP...


Venatic- thanks for the info!

Just plug in your bullet of choice and all other data and it will tell you what you want to know.

This looks like the round I've been looking for. 75 gr bullets @3000 fps and the 85 gr TSX@2750-2800 fps.

By the way I have some limited data for the 6X45 with the new AR Comp powder that I worked up if someone is interested.


Very interested in your data as I am a big fan of AR Comp in my 223. Currently considering the 6mmx45

I have now!
I loaded up to 29.5 gr with two different 75gr Bullets and fired in two guns.
The first was a DTech 18 inch barreled 1/12 twist and the speed averaged 2938fps and it shot 5 shots into .968 with 3 shots under 1/2 inch with a hornady hp.

The next load was the same but with the 75gr Vmax and the gun was a 24 inch barreled Cooper. Speed averaged 3093fps and the 5 shots was .605.

These loads looked like lower pressure than my current loads for each gun but with equal or better velocity.
Looks very promising and I would suggest using BLC-2 data and work up.

I used 25.0 gr and the load was mild and pretty slow 2700fps with 70gr bullets but shot very well.

Here is the process I used for the HBN coating of the bullets in the version 5 guide:

Step 1: Wash the bullets (about 250 6mm bullets) in acetone.


Step 2: Place the bullets and impact media (1.5 lbs #B steel shot) in metal pan.


Step 3: Heat the bullets and impact media @ 240°F for 20 min.


Step 4: Plate the bullets for 2 hours (1 hour 15 min. for Sierra Blitz), adding approximately 250mg 7 micron HBN directly to the tumbler.


Step 5: Remove the bullets from the media.


Step 6: Give the bullets a quick polish with a towel or old T-shirt. You can also place the bullets back in the tumbler with old newspaper or cloth strips for a real shine. Personally, I don't think the prairie dogs can tell how shiny the bullets are.

What is an HBN coating, and why is it of benefit?
