Everyone on here has damn good advice. The biggest thing to remember is that it is a mental thing,you have to convince yourself that its not going to be as bad as you think, that it is just an after effect. If you use these steps, you should do fien.. My personal hunting rifle is a 300 win mag, and I stepped up to it from a 243, it was a huge difference. I got advice similar to what you got here, and I can go through a box of shells now before I notice myself flinching, and my group size starts to grow. If you are a sick twisted individual like my dad says I am you can learn to enjoy the recoil, the feel of power I guess LOL. While over here in Iraq, I have got several opportunities, to shoot a Barret 50 cal Sniper Rifle. The felt recoil isnt bad, slightly worse than my 300, but the shockwave from the brake is immpressive to say the least!!!!
