.308W load development and testing
@ 01:34 pm (GMT) |
Dennis MahonyJust a general question that came to me one evening, from a first time reloader here...I am about to start reloading some .308W for testing and development, in a freshly broken-in rifle (as per the Tikka vimeo clip). The ammo will be for general hunting in open-top country and open bushland. Apart from doing tests in increasing grain increments and finding the most accurate load from these tests, would I then fine-tune my most accurate load even further with seating depth tests afterwards? Is this how load development is done normally anyway? Or should I just "let sleeping dogs lie" and leave an optimally charged load alone? Thanks and regards, Dennis Aus |

Nathan FosterRe: .308W load development and testingHi Dennis, yes, thats all correct.Using U.S made brass (not ADI) and 2206h, coupled with a Hornady 165 to 168gr tipped bullet seated to 71mm, you will want to test from 42.5gr to 43.5gr (3 shot groups / half grain increments). I test to 44 but cannot condone this as it is .5gr over book max. The Tikka sweet spot is normally 43.5gr. Then as you say, if you are not completely on the money, you can play with seating depths and or .2gr increments etc. |

Dennis MahonyRe: .308W load development and testingThanks Nathan, much appreciated. Why U.S brass over ADI out of curiosity? (I do have your reloading book - if the answer is there - but I haven't read/absorbed it all as yet). |

Nathan FosterRe: .308W load development and testingHi Dennis, ADI brass is quite thick, loads can end up compressed. Its easier to work with a U.S brand - apples with apples as far as data goes. If you have a pile of ADI, perhaps just set it aside in an air tight container for safe keeping. |
