The computer results seems somewhat flawed. .30-.30 is a cartridge, not a caliber. A caliber is a diameter of the bore or bullet. Also, an ideal cartridge for a whitetail deer in brush country in the northeast may not be best for whitetail deer in an open farmland in the Midwest. Did the study call for any deer, or whitetail deer specifically?
I’ll pass and just go by my own experience. YMMV
The author is also deficient in basic grammar skills.
Yes, it is. The moniker is ".30-30" and represents .30 caliber and 30 grains of smokeless powder. It is also known as .30WCF which is the round my 1894 rifle fires.
