Re: Proper bench technique for big bore rifles?
By big bore and kick a little, I take it you mean 338 Win and above.
For my bench shooting which is very much the same a prone w/bipod here is what I do, not in order of importance. This works for me:
a) Ensure the rifle is naturally on target with fudging nothing but the rear bag. That is, with heavy or light cheek pressure the rifle just lays there with the cross hairs on the point of aim.
b) Very light and consistent cheek weld.
c) Firmly pull the rifle STRAIGHT back into the shoulder and lean into it with out moving the rifle. If you lean differently shots may tend to string vertically.
d) I've found that a straight pistol grip with palm swell to be much preferable to what is on the sporter/hunting stocks.
f) Touch the trigger with the center of the first section of the trigger finger. Even with the back of the finger nail. (I'll probably catch flak on this.)
g) Set the fore arm on the pedestal/sand bag right where you would put you hand if shooting off hand.
h) One hand on the trigger/pistol grip pulling straight back. The other hand on the rear bag to squeeze for elevation adjustments. Let the front of the rifle do what it will. However, be careful to not let it jump off of the pedestal rest. That's not a good thing.
