The only time I regretted it I had a .30-30 with a 4 X scope in my hands and saw an honest 32" mule deer buck a tad over 300 yards away...out of my comfort zone with that rifle, and he walked out of my life forever...
The owner of a deer camp I used to go to called the 30-30 a "sharp stick". When I asked him why, he replied that if you were looking over a large clear cut with one in hand and there was a nice deer on the far side at 300yds, you might as well be standing there with a sharp stick in you hands.
He was right.
