[QUOTE="Padmi, post: 2014008, member: 109877"] Hi guys! Yesterday I was reloading to check my new loads in the rifle. I got a question, my last rifle barrel was 24inches length 19mm of diameter, 1:8 twist 4140 carbon steel The ridgeback (the new one): 24 inches lenght 21mm of diameter 1:8 twist 416 stainless steel So steel is different and also diameter. I realized in the new one, rifling is further away from the previous one. I always followed saami measures to use the maganize My best recipe to the last rifle: Hornady ELD M 147GR BR 4 primer Lapua shell 41.5 grains of RS 60 powder (european brand) OAL 2.75in Do you guys think that I can start from the old recipe? I will make the following trial Powder charge: 41gr 41.3 and 41.5 OAL: 2.75in, 2.8in and 2.83in My question is, if the diameter and the material of the barrel changes, do you think both barrels will have a similar accuracy with the same load? Thanks so much in advance [/QUOTE]
