Doesn't matter, aluminum is far easier to machine. Experiment, replicate other designs and try'em. Don't bother with anodizing, VHT paint and a toaster oven. Aluminum will burn out faster than steel, depending on load. Full house 223 maybe 1500/2000 rds.

How long is the ejector?

Mag and rifle primers have more brisance, harder cup and equal to .1-.3gr of powder.

Thx zzt, more info the better!!

CWA conversions only work with GSG mags.

Use what you have, learn how to do a trigger job (fairly easy without $$$ parts). RimfireCentral has info. If you're hard over on a compensator, look into Scheuman style barrel porting.

used dillon presses are still under the life time warrantee

There are some fumble fingers out there. As much as I like nasty COF's, I've toned them down for new shooters.

Get some Lego's they're even better on bare feet.

May be possible to salvage the sear if you have a sear jig and stones. I suspect you are new to 1911's. So was I at one time, and I'm still learning. If you want to learn how to do a trigger job, use GI parts from SARCO or similar sources. Expect to trash some parts, that's the idea. Besides the sear jig and stones, a jeweler's loupe is handy. Today's hammer and sears are a drop in compared to 20 years ago. Most I do is de arc the 3 finger spring and tweak for trigger pull and a safe hammer. (sear finger).. Once you have a grasp of the operation, experiment. Any time you do a trigger job, rack the slide on an empty gun 20 times. If the hammer follows or drops to half cock, repeat test but hold the trigger forward. If it doesn't follow, disconnector finger tension is too low or the trigger itself is too heavy. Don't be afraid to ask knowledgeable people on your squad, they are usually willing to share.

Hammer half cock has been hitting the sear face. Back out the trigger over travel screw until sear clears hammer. Once there is clearance, give a 1/4-1/2 turn more. There is one more test. Hold the trigger back and ensure slide cycles smoothly. If there is a hitch or the slide is held back, the problem is your disconnector is binding. Disconnector i binding is caused by trigger bow over travel. Inspect your parts for peening, at the least a new sear. Wish you'd mention that tick before.

Generally, 22lr conversions don't like 17lb main springs for consistent ignition. No sure why you need parts after 3K rds. What is the problem, ignition, hammer follow?

These guns are dirt simple, so are the solutions. I suspect dried out lube of some sort.

Does the hammer cock and release easily? Either gummy pins or hammer spring. After cleaning, try Brian's slide glide on the hammer face

On Target in Mission Viejo used to have indoor IPSC, RO'd a guy with a laser. Fun to watch the Lissajous patterns on the ceiling

Certainly the ammo is cheaper, real benefit is watching your sight picture during the shot. It will tell you how well your grip works and if your trigger finger pulls the gun down. Local indoor range had weekly rimfire steel challenge. Took 12 seconds off overall time. Mind you, I was the only rimfire shooter drawing from a holster. You have a 1911, 22lr top ends I've tried are CWA, Marvel and Nelson. All are very good and similar pricing. CWA uses GSG mags. Nic Taylor has a 16rd mag kit for GSG's. Try a reddot, been using Vortex Viper and Venom. Have 3 and 6 MOA, honestly I like the 3MOA (indoor ipsc) https://www.youtube.com/watch?v=li0rGtXh23I

Powder likes moisture, causes clumping. Do you leave your powder out in the powder measure?

Every part is a consumable, how far you go depends on your wallet and gun bag size. Barrel links, no. Mine are married to bbl / frame / slide. Mag springs maybe, spare FP and spring yes. Extractor and maybe an ejector.

ROs' are volunteers, they are lucky to get a tee shirt at a big match. ROs' enforce the 180 rule you can't duck fast enough.

CLR has phosphoric acid, good bye anodizing

Good catch, I should clarify the Nelson wide mags won't work. The follower gets stuck under the feed ramp. Milling the feed ramp doesn't help. Entry angle too severe. edit: GSG mags with the Nic Taylor mag kit works very nice (not available in some blue states).

Outer Limits has a plate at 40yds, Speed Option 35yds.

Marvel Precision, Nelson Custom and CWA are all very good 1911 uppers. CWA only works with single stack, will not work with a 2011 frame.. CWA can use GSG mags. Nelson Custom has the best price for double stack frame mags, no feed probs.

Good reason to get a rimfire BCG conversion for your AR, CMMG or M-261. Black Dog has mags for both. 1/7 twist will work, or the dusty 1/12 bbl is even better. Dedicated upper is the way to go. Don't worry about rimfire fouling the gas tube, the first .223 will take care of it. We are shooting indoor IPSC/Steel Challenge in Torrance, Ca. FYI, RTB.com has had the best prices for CMMG BCG's
