not that they are eldx bullets but midway does have some 140 and 145 barns match burners in stock either way that only a tiny bit off of the 143's . either way good luck finding the exact bullets your looking for .
only bad thing you are limited to only 2 so I went with the 500's or have you ever looked into the solid copper bullets cause cutting edge still showed having the solid copper 143 gr bullets in stock just another option maybe .
They are out there but you have to be on the hunt. I traded off a bunch of powder and bullets the last week and now I have like 300 143gr eldx bullets. It took a lot of trading and communication. But worked out for me. Also, traded 30cal bullets on rokslide for 143eldx. Buddy has some back ordered on optics planet not sure how that will turn out. I still see some that last for about 5 minutes if you can get one of those notification apps.
