At last I got out and shot with my 4.5x14 Leupold vxIII with Boone and Crocket Reticle.
I was shooting an H-S Precision .300 win mag with 165gr ballistic tips at 3400fps.
I measured all the ranges with my Leica 1200 scan rangefinder.
I zero'd the rifle at 250 yards then shot 3 shots at each aim point on the rifle. I figured them out to be
250 on the crosshairs
350 at the first aim point
500 at the second aim point
550 third aim point
600 for the bottom post
After shooting 3 shots from each position I measured the group for all 15 shots and it was 6".
Maximum verticle dispersion was 4".
So for my rifle with my load the reticle works great!
Of course it helps when the rifle shoots a 1" group at 250 2" group at 350 and a 4" group at 500 and a 5" group at 600.
I second the B&C reticle. I returned last week from my 1st antelope hunt. Me and my father went to Raton, NM. My leupold VX3 4.5-14X50mm w/ the B&C reticle helped me to take a 15 3/8" long antelpe @ 452 measured yards. I just put the 450 yards crosshair on him and squeezed. For me that is the 3rd one down. I was using a Tikka T3 in .300wsm w/ 150 gr Sierra BTSP loaded w/ 58 grs of IMR 4320 that averages 3,044fps. With this load the scope works wondeful! My Dad also took a 14 1/4" long antelpe @ 355 yards w/ his .308 win.
