Not a group but the first year deer hunting I was hunting with my TC Hawken and I put the sights on a doe at 75 yards and shot high and completely missed her and hit the doe standing behind her right in the side of the head killed her graveyard dead. she didn't make another step. Strangest thing I have ever done since.

2 groups come to mind. The first time I tried BM3 with a 460NE shot a 12+" group at 25 yards, didn't try 100. Another group was an experiment with a 54 Bobcat using 50cal REAL 320's in a .022" patch, I hit the 18" target 2 out of 5 shots at 15 yards, then gave up, bad idea.

At 100 yards with a good bullet and load not tweeked maybe 6" to 8". With a good bullet and tweeked load the best was about .5" for 5 shots.

Oh, i have had some awful groups:Have a tendency to run hot or cold, little inbetween. Bought someones cheap sabots one time and tried them with my 240 grain cheap semi-wad cutter bullets. They would notstay on the Army silhouette target at 50 yards.
