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.

I only have 18" but I really like that length. Enough velocity, not too unwieldly with a 6-7" can. It's already on the verge of being ass heavy so no desire to go shorter for open country hunting. Wouldn't hate a little less length for treestand/blind hunting.

For an 18” with a 5-6” can to be ass heavy, are you using a heavier chassis and titanium can?

Most of mine that are suppressed, even with shorter barrels, with wood and carbon Sporter stocks, still lean a bit nose heavy. I don’t have the lightest suppressors in the world tho.

My 16” 6 creed pushed 109s at 2900 and 115 DTACS at 2860. If I recall correctly, I was shooting the factory 108s around 2760.

Probably a bit biased by recollections of shooting in a krg bravo. But IIRC even in a rokstok with a Scythe, flat cap, no cover, putting it on a bag in front of the mag it wanted to teeter towards the back end. I mount my scopes further back than most as well which likely plays a part. Not an issue by any means with rokstok and probably not a factor worth considering much if a suppressor will be used.

I’m debating this same thing with myself, how far to cut my 23 inch barrel to accommodate 6 inch suppressor.
I’m planning to actually take a day and chronograph my load that day, cut it to 20 inches, chronograph again, depending on that keep cutting and checking fps until it’s within 1/4 inch of what will work for me.
Then take it to have that last bit cut properly and threaded.
I really hope I can end up with 16-17 inches so the total length the same or slightly shorter than my current 23 inch barrel.

I went 18” on mine. Happy with the balance. Factory 108 ammo is just shy of 2800 out of my rifle. Could probably get a little more with handloads.
