clip the ejector spring a little. Mine spits brass about 4ft off to the rear right depending on load some hotter loads will still sling it pretty good. When I first bought it, it would spit brass about 15ft from where I was shooting in prone.
Dont cut the extractor spring, but the actual ejector spring.

i clipped 1/4 coil at a time until it was ok. buy a spare just incase you go to much
