I am looking for a long range rifle in a smaller caliber. I shoot several guns on the AR Platfrom, but I want a caliber with more oomph than the .223. I really want to shoot a bullet with a high b.c. I have shot the 75gr and 77gr bullets in the .223, but I feel more velocity will stretch out the effective range. Plus I have a nice Rem 700 V in .22/250 that I want to modify.
