I have just loaded up with 52.5 gr of N560 some hornaday 130 SST in 6.5. I chronographed them at 3070 fps. This seems to me to be factory 270 territory. Does the 270 fire 160 gr bullets,and get down to 85 grain fox rounds?
Is its powder efficiency better than the 6.5 ?
Which will go further and drop less , a 6.5 bullet or a 270 bullet of the same weight going at the same speed?
With gentler loads which is better for throat erosion?
