Shorty 6 Creeds

[hereinaz]

Looks like chatgpt loads to 90k psi.

You’re getting in the weeds. Get a br, gt or a dasher, reap the benefits of accuracy and ease of loading. Put 3k rounds through it in the next year and you won’t need to ask us our opinion, you will know what you want.

This is true, you are slicing the differences off so thin that in practical terms performance is so similar to be identical for the ranges you are talking about.

The benefit of the short fat cartridges are super easy loading for consistent accuracy and low ES for long range work.

I waste a lot of time screwing around with this just because, and, it’s fun.

Bottom line, the differences at the range keep showing me that much of the hand wringing is irrelevant when it comes to lead on steel and flesh. It’s trade offs that don’t end up being material when it comes to results.

I have a 16" in 6 Creedmoor running at 2675 with 108 elms. I see pressure signs when going hotter towards 2750.
I have tried several powders (N555, H4350, Varget) and landed on N150. I also saw the exo guys talk about using H4350 which is what I tried first but if you plug all this into something like GRT or Quickload you'll see these slower powders do not get full burn in a 16" barrel which is a problem to me. Unburnt powder results in wild ES and SDs and can also hurt accuracy
This probably the biggest consideration for me when thinking about using a shorter barrel.
There is a balance between optimal case fill and burn rate that has to be achieved to get consistent shooting ammo.
Extreme spreads of 50 fps + might be acceptable for you or others and if so then this will make load development easier for you.
It's true that will probably be easier to do load dev for other cartridges like GT or BRA, that are know for being very easy to find a good shooting load but that's also in the context of usually a 24" -28" barrel length in the competitive world, which is very very different than a 16".

Roger that. I'll get roll with the 22 GT and call it a day. Just for the fact that when the kid rolls an elk with it this fall it'll make the Fudds cry

Yeah haha I definitely don't trust the AI for load data. If I ask it for data I'll verify it with other sources from published.

I have two sig cross’s both have proof 6CM barrels. -20” & -16”


They both shoot the same load very well (alpha srp brass, mag primer, 47.2gr 4831sc, 108 Berger EH.) 8000ft elevation

20” shoots - 3118fps

16”shoots -2881fps

The 16” is a cross stx, it’s a sweet little gun! 5” nosler can (loud but better than a bare muzzle) and a 2-20 Nx8 - weighs 8.4pounds.



Also I have a 26” comp build 6gt- that one is impressive. Alpha brass, 35gr varget 108 Berger 2996fps.

16” 22GT will be nice. I have a 16” ruger G2 22arc now running 80eldms at 2970fps stuffed deep in the case. The GT will give you another ~150fps with 4-5gr more powder. I also run a 16” 243win, 87gr at 3150 w handloads. But at 16” its much more pleasant to shoot arc/Br/GT sized cases with low recoil and less noise suppressed.

Looked up 22 GT data on hodg's site. They're doing about 3000'ish in a 24" with an 88 grainer. 108 and a 6 is about the same.
Plugged the numbers into 4DoF after taking about 240 fps off for a shorter barrel.

They're basically identical out to 7-800 yards

Scheels has 88 grain eldms for 22 bucks a box vs 42 for 108's.

So there might be a small percentage difference in the size of the wound channel with a 6 but I doubt it'll be noticeable.

I believe it’s Ernie on here that runs a 16” 22GT pistol. He was pushing 88s at 2940 with rl26 and 3073 out of his 18”.
I’ve been buying 75eld arc ammo for $22/box also if you buy in bulk. It’s certainly a big plus for the cartridge and guys that shoot factory ammo.

Just an FYI, the general consensus is that the 75 ELDM and the 80 ELDX give better wound channels than the 80 and 88 ELDM for most shooters. Not that the 80 and 88 ELDM are poor, just not as big or consistent as the 77tmk, 75 ELDM, and 80 ELDX. This is based on guys shooting the 22CM for hunting.

If your building a 22 cal id be building it around the 80eldx.

Personally I don’t feel the barrel life loss is worth it going to 22 cal. On paper my 22 creed had less recoil. But the reality was that my even lighter dasher is easier to shoot, and has similar gun number. Plus the fast 22s do too much damage at close range ime
