RE: Heavy or light?
I find it interesting how many people think theres such a big difference in the trajectories of a 250 and 300 grain bullet. In comparing a 250 and 300 Shockwave shooting 130gr of pellets there is only about 1.5" difference in them at 200 yards, around 2" at 250 yards. That works out to about 8 yards difference in 6" point blank range, 194 vs 186. The 300 has a better BC and retains velocity and energy longer even though it is close to 150fps slower. With this load at 200 aim a few inches high, at 225 put crosshair on the back, 250 a couple of inches above the back. With either one you'll be in the kill zone.
At 100 grains of powder theyare closerwith the 300 down about .75"more at 200 and 1" moreat 250. 6"PBR's are 176/250 and 173/300. Not enough to worry about.
