    lenth or powder

    if this is I the wrong place then please move it I am looking at loading .308 for a 1.10 twist barrel and have a coal and have measured to the lands. even giving 20 thou off the lands a sammi spec GGG round is 60 thou off. I am using Swiss reload and have data sheets from them regarding the nominal weight of propellant to the weight of the head should I 1 load the rounds in .5 of a grain to find the best for the rifle leaving the head 80 thou off the lands or 2 start with the nominal load and set the distance from the lands? I don't know whether to set the distance from the lands or sort out the charge first any thoughts or help will the greatly appreciated this is the first time I am reloading .308 and don't want to bugger it up many thanks

    ​thanks for all your replies my rifle is a Bergra B14 HMR with a 20”/1:10"Twist in .308 I have Zeroed at 100 yards and it hits out to 1000 yards with GGG 155gn rounds from Bisley armoury out of the box. I am looking a reloading to tune the round to the rifle and to tighten the groups. and was advised to get 155gn sierra heads and lapua brass as well as RS60. this is a very steep learning curve for me and I will be honest am nervous as hell. I reload .38s and have just bought a Gen 6 Lyman powder dispenser to better load to the 1/10gn. again thanks for all your advice thus far.
