Rifles only....correct? Not pistol rounds in rifles?
1. .444
2. .375
3. .45-70 Gov't
4. .30-30
5. .356
Also, I enjoy utilizing my .405, .348, .307, .300WM(a little), .30-06, .308, .30 Cal M1, .32Wspl, and if I could classify it as a cartridge, my all time favorite....50 cal round ball ML in a Lyman Great Plains Hunter.
If I could use a pistol round in a rifle, the .44 Mag wins hands down. I shoot a coouple of hundred rounds a week in my Trapper and Legend, but it is not a rifle cartridge.
Notice I did NOT mention any of those foreign measured girly, girly stuff.
