I had a problem with reloads chambering. They all fed and fired fine in my 1911. The LWD barrel has tigher tolerences and lead bullets are larger than jacketed bullets by .001" to .002". I eventually learned to adjust my loading procedure to get cartridges to chamber properly. I was using a roll crimp die which worked 90% of the time. Since then, I've moved to a taper crimp die and have had no issues.LWD barrels are stainless so you won't have to worry about rust. I'd check to make sure your ammo of choice will chamber properly in the barrel before you try to rack a round into the barrel. You can do this one of two ways, either just drop a round into the barrel while it's off of the gun and check to make sure it's going to clear the barrel hood by laying a flat edge across the barrel hood or you can put the barrel into the slide and as you drop it in have a dummy round that you can let slip under the extractor and into the chamber as you seat the barrel into the slide. Either way will let you know if you'll have enough throat in the barrel to work with your ammo of if you'll have to open up the throat area of the barrel(like I had to) in order to work properly.
I plunk/drop test every round now just to be sure.
