[QUOTE="merbeau, post: 995614, member: 38494"] The temperatures are starting to cool off in Texas and my attention is starting to focus on building a load for my 338 RUM configured in a Browning A Bolt with BOSS system. I am planning on starting with Lapua Scenar 250 grain bullets using Nosler brass and Winchester large rifle magnum primers. I am looking for accuracy more than velocity. Problem is powder. I have several pounds of IMR 4831 and 4350 in my reloading room. According to the Hodgdon web site they list both powders for this particular cartridge. I have read where Retumbo, H1000 and IMR 7828 have been used for producing accurate loads, however, trying to find these powders has not been successful. I have read in other forums people claiming 4831 and 4350 are to fast for the RUM, however, if that is the case why publish a recipe for it? Of course Retumbo, H1000 and IMR 7828 use copious amounts of powder which obviously contribute to less barrel life. Has anyone had experience in using IMR 4831 or 4350 in the RUM? Typically I try to find a powder that give the best group with the BOSS set in its optimal setting and then fine tune the setting to obtain the best group. Thanks Robert [/QUOTE]
