The 22 creedmoor thread

Graphite never worked for me. It dosnt stick to annealed necks like you would think, and not consistently. I havnt touched one since I tried the above method.

Fresh brass gets imperial lube in the neck, a carbide turning mandrel, and a one hour dry tumble in semi dirty media. Chamfer as normal and it loads like fired carbon covered necks.

You can dip the bullets in graphite instead, but I haven’t had issues with tight alpha brass using a 2 thou mandrel and ceramic beads with graphite…

I much prefer the simple loading methods Form has described, messing w my mojo. This is a PITA.

Run it over a mandrel or through a sizing die with expander ball. Tumble in well used media. Go forth.

Or just shoot it with large deformations, 2nd firing will be better.

I tried that too. Wasn’t happy with the results. I havnt used the beads or graphite in years.

Alpha is pretty good out of the box when it comes to physical dimensions. Much better the lapua or Peterson in that regard.

I had the same thing happen to me with 2 boxes of alpha 6dasher. For whatever reason that lot gave me problems until I tried neolube given to me by a mechanic at work. It seems like very fine graphite suspended in alcohol that dries with a very nice slippery coating when applied with qtip.

Spray all the insides of the necks with Hornady one shot.

This is what I do, with a q-tip sprayed with one shot, wipe the inside of the neck. Works well on new Alpha brass when loading 22 Creed, but I do with all new brass, regardless, .223, etc, on first loading.

We are in for double digit big game kills with the 80 ELDX. My wife made an excellent shot on this doe at 208 yards. Neck shot and she dropped like she was hit by lightning. DRT.

Now I get to build another 22 Creedmoor as she wants trade her trusty old 243 in for one.

My alpha brass did they same thing - super tight neck tension to the point of deforming projectiles. Once I ran a mandrel through it, I was able to seat projectiles just fine. No issues after the first firing.

Is anyone using the 77 LRX in the 22cm? I’ve searched but haven’t found much info. I know non lead isn’t the preferred projectile around here but I’m trying to play by the rules.

I see Barnes lists a minimum of 1:7 twist for the LRX. Has anyone tried them in a 1:8? I would like to not limit myself to the LRX, would a 7 twist limit my ability to use 77tmk, 80eldx, or 88eldm?

Is there any reason why you couldn't do a 22CM barrel with an outside diameter of 0.5"? Is that a bad idea?

I want to buy a PVA Taperless barrel, but I'm wondering if I could get it thinner than the 0.68". My UL AR has a Shaw barrel that is 0.5" for the last 9".

I have a 270 that is .565 at the muzzle. The walls are only .144 at that point.
With .500 at the muzzle, you'd have .138 walls from a 22 centerfire. .512 at the muzzle would give you that same .144
