RE: RANDOM..Has it happend to you
Have you shot the 30-06 much before this range session? If not, you probably need to limit yourself to less than 30 rounds (if that is where your flinch started). If I shoot 25-30 rounds of just about any kicking caliber (which I haven't done very many times), I tend to start to anticipate the shot (not so much of a flinch). I bought a Caldwell Lead Sled a couple of years ago mainly for my youngest son, but I love the thing. I can shoot my 375 H&H all day without the usual sore shoulder.
