I need some help with any loads for a 30-338 Lapua (AKA .300 Lapua) please. Mine has a .344 neck and 0.188 freebore. I have to supply the proof house with a moderate top load and then 5% & 10% above this. I am not allowed to shoot the rifle first, so cannot work up a load for it.... Normally they would use a standard and then 'proof' load that is on their books. However they've only ever had 1 rifle in before and for that the smith provided the load for it. There are less than ten 30-338 variants in the whole of the UK (i.e out of 60,000,000 people)! So I haven't got many people over here to ask! Also I have 210 grain Berger's to hand to supply them with. Any loads greatly appreciated.
