YOUR SIZE DOESN'T MATTER TOO MUCH WITH RECOIL IF YOU GET IN SOME GOOD QUALITY SHOOTING PRACTICE.
I HAVE A FREIND WHO IS 6' 3" TALL AND WEIGHS 177 POUNDS. HE HAS BEEN ON HUNTS TO ALASKA AND AFRICA. HIS GUN OF CHOICE IS A .416 RIGBY, THEN THE .375 H&H MAG. HE HANDLES BOTH OF THESE GUNS BETTER THAN GUYS THAT ARE SHORT AND STOCKY OR TALL AND BROAD SHOULDERED. THE KEY HERE WAS HIS SEASONED SHOOTING EXPERIENCE.

NOW DONT GET ME WRONG, I DONT RECOMMEND GOING OUT AND BUYING A 450 DAKOTA FOR YOUR FIRST GUN. CHANCES ARE YOU MIGHT NOT EVER WANT TO SHOOT ANYTHING LARGER THAN A .338, AND THIS IS FINE, TRUST ME.

I WOULD RECOMMEND GETTING YOURSELF A GOOD 22 CALIBER RIFLE. LEARN THE FEEL OF TRIGGER PULLS. THE 22 IS THE PERFECT GUN TO GET USED TO PROPER GUN CONTROL AND SQUEEZING OF TRIGGER WITHOUT FEAR OF RECOILS. ONCE YOU ESTABLISH YOUR PROPER HANDLING, YOU MIGHT WANT TO CONSIDER A LIGHT RIFLE LIKE A .243 OR 7MM-08, OR MAYBE 30-30....(THERE ARE OTHERS BUT THESE ARE JUST SUGGESTIONS) IF YOU PLAN ON SHOTGUNS, YOU MIGHT WANT TO START OUT WITH A NICE 20 GAUGE EITHER IN PUMP OR SEMI AUTO.

AFTER YOU HAVE SHOT ANYONE OF THESE KINDS OF GUNS AND GET SEASONED WITH SHOOTING THEM, YOU WILL REALIZE THE NEXT LEVEL YOU MIGHT WANT TO GO TO.

WHO KNOWS, YOU MIGHT END UP ONE OF THOSE GUYS SHOOTING HUGE MAGNUM LOADS......YOU JUST NEVER KNOW.

MY BEST ADVISE IS PRACTICE, PRACTICE, PRACTICE.....AND LEARN PROPER HANDLING AND SHOOTING MECHANICS BEFORE YOU JUMP UP TO THE MAGNUM CARTRIDGES.
