243 Winchester

The 100gr hornady btsp bullet is to long for that short barrel/twist. Velocity is not high enough. H4350 is a perfect choice or IMR 4350. . Try a Sierra 85gr HPBT # 1530 for deer. Work up a load to about 42 or 43 gr in Win or Rem brass. CCI Br 2 primer. Or use a flat base bullet that is not as long.
