Done some chronograph testing with my home loads at the weekend and was pleasently surprised at the results especially as my 270 has a 20 inch barrel and caused me many a sleepless night ! First loads were 130grn gameking with 57.3 grns of RL19 and averaged 2856 fps. Next up were the 110grn vmax with 52.5grns of Viht N150 and they averaged out at 3196 fps, all fairly consistant as well. Brass used for the 130s was hornady and brass used for the 110s was federal all loads used cci 200 primers. Going to try some norma brass and cci br primers next to see if that improves consistancy.
