http://www.longrangehunting.com/forums/f19/111-long-range-hunter-300-win-mag-67605/index3.html Post # 16 by "liltank" talks about adjusting the firing pin if the bolt jumps left during a dry fire. (I assume he meant rotate left?) This rifle does, but not every time. Also, who makes a good sporter hunting stock for this rifle? What bullet weights are typically producing the best groups with this rifle? It shot it's best group today of 2" with a 200g LRX, 79.5g of Ramshot Magnum, COL of 3.362. All other groups have been randomly spaced 3-5" with both factory and hand loads. Pretty pathetic. There are zero issues with scope/scope mounting. (Nothing is moving). I also read where someone said that his rifle didn't shoot well if it was clean. This rifle hasn't shot over 8 rounds before getting cleaned, so maybe I need to let it build up? Any help will be greatly appreciated. Thanks!
