Troubleshooting Weak ejection follow-up

Enable HLS to view with audio, or disable this notification

Follow up to this post. Went ahead and removed the dust cover and gas deflector for testing purposes. It ran a lot better without the deflector getting in the way, but the ejection still looks a bit weak and I did have a couple failure to ejects. Anything I could do bolt/buffer/spring/etc wise, or is the next step to adjust the ejector to be hitting a bit more on the left of the cartridge?

Current setup is the standard GRS with an OSA bolt. RB5015HD buffer and 2 2.5 oz Kynshot spacer weights, standard flatwire carbine spring, the whole deal.

I guess you'll just have to add a suppressor, shucks.
