Hi guys,
first email. I'm developing loads for my TRG42 in .338 Lapua Magnum. Close range shots phenomenal accuracy, 500+ still searching. COL is governed by magazine length. I've tried Reloader 22 as well as a number of Australian made powders - AR2225, AR2213sc and a couple of others. I'm using Sierra 250grn HPBT, Remington mag primers. I've been searching for Retumbo but am having problems getting it in Australia. Am looking at Reloader 25 as it's slower than the RL22 but cannot find tables where they specify .338LM loads. Even Alliant cannot help as they haven't developed loads for this calibre.
Can some of you gurus help please?
Max
