03RN:
Here are a couple of thoughts to ponder.
1. Are you shooting factory ammunition or reloads? If reloads, be sure your rounds are full length sized. Try loaded rounds in the cylinder of your weapon. They should, ideally, drop in and need no additional pressure to seat. The unfired rounds should literally drop free of the charge holes when the muzzle is elevated. One thing I do is check my carry ammunition by loading it into the charge holes of what every revolver I am using. If those rounds fail to seat without effort or fail to drop free , they are relegated to practice ammunition. Even if you are using factory loaded ammunition, you may encounter rounds that are quality control challenged. I have seen this with a variety of brands of ammo. The current high demand contributes to this.
2. During the match did you shoot both 38 Special and 357 magnum ammunition? If you shoot 38 Special rounds then shoot 357 magnum rounds, that may contribute to some seating difficulty but that usually requires quite a bit of 38 Special rounds to affect magnum cases.
3. If you are shooting reloaded ammunition, ideally your fired rounds should require very little force to eject them. I noticed that none of your cases fell out of your cylinder before you initiated the use of the ejector rod. That may be caused by high pressure loads or old brass that has been resized a number of times. Have you used the ammunition you fired in the match in any other revolver and experienced the same issues? If so, I suspect you have an issue with your ammunition. I also tumble my brass between each loading. I reload most of my ammunition. I prefer plated bullets for most of my training.
4. One of my most used accessories is GI bristle brush. When I shoot a revolver, I usually brush the face of the barrel (throat end), the face of the cylinder, and underneath the ejector star about once every one hundred rounds. A couple of unburned flakes of powder under the ejector star can be a vexing problem and I try to stay well ahead of the curve cleaning that area. A clean revolver is a happy revolver. Having a chamber brush handy and giving your chambers a quick brushing out is a good idea.
5. Safariland Comp IIIs are my favorite speed loader. One of the benefits of using Comp IIIs is that I can keep my revolver oriented towards the threat with the muzzle slightly depressed and still get the gun reloaded quickly. This lets me maintain my situational awareness instead of dropping the revolver to my belt line and using gravity fed speed loaders. I don't like taking my eyes off of a threat that I just fired a cylinder's worth of ammo at. Comp IIIs work well in this area.
Anyway, food for thought.
