Here's one of the best low velocity impact pills I've used but i don't think they make anymore

Don't have any of the woodleigh left that magnum maniac talks of as they were a touch better ( this is in design a round nose is a better design terminally but range dependable for impact velocity )
The coppers on this if I was to go that way i would be extremely careful in following minimum recommendations on them but the subsonic variety should work well for this application as surely they would open to a big enough meplat % plus sub velocities
250 weight class is where I'd limit my weight choices but lower I'd be in this situation & choose wisely on pill preformance capabilities
Watch the velocity impacts people are using when giving advice as this is extremely critical for you
