Has anyone tried Barnes X bullets or O bullets in the spitzer or semi spitzer types? I am huntinig KS this year and stubbornly want to use my favorite No 1. The 300 X bullet has a BC of 340 which isn't bad. Wonder if it will chamer ok in teh short throated ruger, probably desigened for 458 mag. A long shot of 200 yards is a probablity in the open country I hunt. I have more appropriate rifles for this but I really just like my 45/70. My Bear Tooth 405 LFNs shoot awsome, as do 300 grn jacketed, but the trajectory is a rainbow.
