Well the first Creedmoor match was black powder.Have you considered a .45 smokeless muzzleloader? Capable of 1000 yds+!
500 and beyond?What is long range?
Yea, but what is it for the OP? Often in OH, I find the cutoff for normal to long range to be 100-500 yds. In other areas. Short is 0-400, mid is 400-800, long is over 800. Other people push those to 0-6, 6-12, 12+.500 and beyond?
