Can anyone help my with this. Wanting to build a pistol to take to ILl. for whitetail. It must be at least 30cal with a case length not to exceed 1.4". It must also be as a factory load with published ballistic data. This means not 7.62x39 or 30AR. I have found the 300 whisper but not that impressed with 125gr ballistics out of pistol. There is a 30Bellm but I can not find anywhere that manufactures it. Any help is welcome.
