Reviews
I wasn’t happy with the original die set that came with the Presslug system so I contacted Ronnie at GMI engineering to make me a better die set for shooting slugs and did he ever !!! My 30 cal fx sniper now shoots consistently hole in hole results at 50 yards and 3/4 - 1 in groups at 100 yards . Finally a slug die that works. Thanks Ronnie and GMI Engineering
