I guess I shoot bolts a bit different.

I don't shoot off the shoulder except with my 270 Sako.I can work that bolt pronto.Not so with bigger rifles or big Bores.The Sako scope picture stays the same even on high power.

I use the index finger and the middle finger together to open the bolt and the thumb to close it.The problem is to bing the trigger finger at speed to the right position and maintain the scope picture on target.

For me,heavy recoiling rifles mess with this coordinated action off the shoulder signifigantly and primarily the scope picture.
