16.5” vs 18” 6 creed

[_MountainBum]

looking for feedback from those that run shorty 6 creeds, and what barrel length is short but optimal for pushing 108’s. I am mostly between 16.5-18” but would entertain up to 20”

Thank you for your input!

Define optimal for yourself:

Ie.

Density Altitude of your primary hunt locations.

Define a max effective range that is realistic for your capabilities.

Work backwards from there to determine what velocity you need to get to that point. That will inform how long of a barrel you will need.

I am 2850 in an 18" tube with hornady 109 eldm if that helps your decision any. At my typical DA that I am hunting, that puts it above 1800 FPS to 800+ yards.

Man for a 6 creed I’d want to take as much advantage as possible, otherwise I’m just shooting my .243.

For 6 creed and high BC heavies, 18” with factory ammo at mid DA gives you an 800ish yard gun.

I personally like to stay closer to 2,000 FPS impact velocity if I can with the bullets I shoot.

Run some calcs with your planned bullet and see what you come up with. DO NOT overestimate your velocities like everyone does.

I have a 20" 6cm currently. 40gr of h4350 behind a 108 eldm puts me at 2920 mv, no can, 2090 @ 600.

Next barrel I'm looking at 16.5. Target mv would be 2800 with a can, have a bit of room to add powder charge if need be. That would put me just under 2000 @ 600. 5kDA.
