Shoot those up and DONT buy any more like that ! Stick with 147 gr, 150 gr, 155gr, 165 gr,168gr, 175 gr and 180gr projectiles which are ballistic tipped, FMJ ,HPBT or plain Jane pointed tip. Flat and rounded bullets don't chamber well in AR's. Also Always go by BOOK numbers and use more than one BOOK ! If the two books are not close get a third book. NO EXCEPTIONS ! There are some manuals in the reloading sections. If you can't find something ... ÀSK ! I have access to about 9 loading manuals.
