Actually, no I have not. I really like shooting conicals and have always been satisfied with the way the maxiball and REAL conicals shoot out of the 1:48 twist rifles. Also since all I hunt is deer, and usually at very close ranges, even the roundball was plenty.

Bull Shop just started making these .54 caliber and wanted them tested. I of course volunteered for the job. It gave me a chance to shoot all of my traditional rifles. All of my .54 caliber barrels except on which is a 1:70 GMB are the stock 1:48 twist barrels. So this is a lot of learning for me.
