and now they have it covered every other from .243-338....ie...
243 257
260 270
7mm-08 no gap here
308 323
338

Well then,I guess there should be no .257rbts since theres only .007 difference between the 257 and 264(260)? Theres actually a big difference between a 130gn .284 and 130rg .277, in sectional density.
IMO we have no need for anything besides 22lr, 223, 243, 30-06 and 375hh, but I just find it odd that there is no 308based .277
