[QUOTE="swampratt, post: 3562005, member: 15054"] I thought you had a good hunting load for those? Now lets get into brass prep since you are chasing that tighter group. Without good brass prep you are limiting the rifle. Yea 1" to 1.25" will work fine and you need to check that at 200. My tight at 200 and 300 are 1.25 @ 300 and under 1" at 200 but only shoot .75" at 100. Now without annealing the necks each time my groups are larger. Brushing necks is a must do for me before and after resizing. Same head stamp is a must. NO Crimp! Even bullet seating pressures are a must have. I measure neck ID and Neck OD they can NOT vary more than 1/4 of a thousandths of an inch. If you have an OD on one case that is .001" larger the group will show it. .001" different on ID is unacceptable. VLD chamfer case mouths always even if you did not trim the case. Neck brush the cases after all prepping is finished and clean inside neck with a QTip. You want tight groups you must work for it. Look into the cases and notice the primer hole inside the case..some have a Burr I deburr that hole. Oily fingers need to stay away from bullets that you are going to seat into a case. Wash your fingers. Some bullets have a wax on them..Those I clean off with a paper towel. Sizing die wax on outside of case when you pick it up and then you pick up a bullet is a NO GO. Sizing die wax or spray lube in the case to me is another NO GO. Then there is the shooting part. You must have the front bag in the same spot as we know and same hold on the gun. same amount of pressure applied to the butt/shoulder area. Lay your thumb on the barrel when you shoot NO GO. If you can't hold on exactly the same spot on the target at 100 then do not fire the round off. Work on your steady. My 30-30 shoots and kills everything inside of 250 yards and it is slow 2200fps and groups 1.5 some days and .75 on other days. Neck turning really tightened the groups in it. Lapua cases shot horribly in my .223 and .243 until I neck turned them. I like neck turning for accuracy and to eliminate pesky unexplained fliers [/QUOTE]
