I don't know if there's enough room in there or not, but could you possibly glue some thin rubber (like a piece of inner tube rubber or similar just to give a little "cushion") to the front magazine wall?
Might work, might not... but it might be worth a try if your OAL will allow it.
I know it's been proven that damaged bullet meplats have little to no effect on accuracy, but if you're like me, they sure do have an effect on your confidence in that bullet.
