Just in from the shooting range.
I have to say that after all I've seen, heard, and read about heavy recoil on these 2 rifles: HUH....the .458 Win Mag was first up....was going go start with my 30-06 and work up.....screw it....lets just jump into the deep end and get it over with....BOOM....okay there was recoil....comparatively to shooting a 12 gauge 3 1/2 inch mag waterfowl load. Try again.....Try it again.....okay felt that one, didn't get the rifle seated into my should just right, still 3 1/2 inch 12 ga.
Bullets hit the target 2 inches left hit low do high....shooter problem ( I have trouble using eyeglasses and getting good sight alignment with iron sights. Easy fix with a good scope.
Next up is the .375 H&H. Need do lengthen the trigger pull with spacers or a thick "wimpy pad".
First shot into the quarter size black dot I marked on the target, next 4 rounds joined the .458 holes left side. Iron sights, eyeglasses....know the problem and the fix. My 30-06 has a wee bit more recoil.
