I have been looking for a cartridge that will fire the 70-90 gr .224 caliber bullets at subsonic velocity.The .224 whisper 90/221 cartridge has been recommended by my reamer tool maker.
Dose any one here have any experience tips or helpful comments on this combination or a better one.I have loaded for my 300 whisper for years looking for a small bore companion.

No help but if it were me I would be looking into making a cast (maybe gas check) lead flat nose. Should be able to get a heavier bullet to be stable as the bullets total length would shorter than a BTHP style or the same weight. And much more affordable after you buy the molds and pot. But I don’t shoot suppressed... yet!
