I recently acquired a Weatherby Vanguard in .300 WBY. It is going to be used as a back up rifle to my 7 RM. Anyways, never loaded for WBY before. Just seeing if I need to watch anything inparticular and maybe some favorite 180-200g loads. Am leaning towards the 200g AB. I've run a few loads through it with 180g SST's with some IMR-7828 and was getting 2-3" groups at 100 yards. Had a few 180g NBT's laying around and some RL-22 as well so I tried a couple loads. 81g of RL-22 shot .7" 3 shot group at 100 yards. Figured that was decent enough considering my rest, it was windy, and the trigger and stock absolutely suck on that vanguard. Did I mention it kicks the snot out of ya every time you squeeze the trigger!! Haven't cronoed the RL-22 loads, but the 7828 were shooting between 3150-3250fps. Need to crono the RL-22/180g NBT load as it shoots decent enough for back up work. Hoping its around 3200fps.
