I loaded 10 rounds  with 175 Gr of 5010 under my spotter tracer.  Ran them through my single shot  zeal custom

No issue with ejection  of empty case recoil  was about same as my normal rounds or any pressure  signs.

I was only shooting  at a 100 yards range. Into a earth backstop.  
Accuracy was not bad most of my shots where about touching. But they hit about 2" lower then normal rounds at 100 yards.  I had 100% of them to light off but not a single one went bang at the 100 yard back stop.  I could see the bullet burning in the dirt back stop for a few seconds  after it hit.

50 bmg

It was a lot of smoke. I thought maybe been the tracer still burning. I thought the s/t went bang like the api.  Guess I was wrong.

I've done exactly the same. Just whisps of smoke out of the dirt. You need to hit rocks or something with them to get the full effect.

This is the one thing I like about this range.  The soft dirt is safe to shoot tracers into. But lacks the resistance to set them off
