[QUOTE="AKGuide, post: 769413, member: 64701"] I noticed .004" of neck clearance has given me the best groups. So if you have a .338" neck like mine I load them to .334". Also if you get vertical or high ES numbers the federal gm210m primers helped lower my ES and SD with the 220 smk bullet so it should work with the lrx also. With the 210 primer you can load about a grain higher to get the velocity back, for a large rifle primer it is pretty warm. The Barnes bullet likes a long jump it seems and likes a certain amount of powder also. I would start at 82 grains and work up to 85 to 86 grains in one grain increments and then find a node than test in between at half grain increments. A half grain higher or lower opened my groups, but once you get it dialed in this bullet shoots and the bc listed is pretty close I haven't done much testing beyond 300 yards but that will change shortly. I forgot to mention that i coat these with HbN to keep the copper fouling down so your max load may be lower than mine. It is almost none existent after twenty rounds a few wet patches of cr-10 is all it needs. Reuben [/QUOTE]
